Beyond the Bitcoin Bubble Yes, it’s driven by greed — but the mania for cryptocurrency could wind up building something much more important than wealth. In the lingo of cryptography, they’re known as my seed phrase.
They might read like an incoherent stream of consciousness, but these words can be transformed into a key that unlocks a digital bank account, or even an online identity. It just takes a few more steps. On the screen, I’m instructed to keep my seed phrase secure: Write it down, or keep it in a secure place on your computer. That string is my address on the Ethereum blockchain. Ethereum belongs to the same family as the cryptocurrency Bitcoin, whose value has increased more than 1,000 percent in just the past year.
Ethereum has its own currencies, most notably Ether, but the platform has a wider scope than just money. You can think of my Ethereum address as having elements of a bank account, an email address and a Social Security number. The whole exchange takes no more than a few minutes to complete. From my perspective, the experience barely differs from the usual routines of online life. But on a technical level, something miraculous is happening — something that would have been unimaginable just a decade ago. I’ve managed to complete a secure transaction without any of the traditional institutions that we rely on to establish trust. And the platform that makes all this possible?

There are no venture investors backing Ethereum Inc. As an organizational form, Ethereum is far closer to a democracy than a private corporation. No imperial chief executive calls the shots. You may be inclined to dismiss these transformations.
After all, Bitcoin and Ether’s runaway valuation looks like a case study in irrational exuberance. And why should you care about an arcane technical breakthrough that right now doesn’t feel all that different from signing in to a website to make a credit card payment? But that dismissal would be shortsighted. If there’s one thing we’ve learned from the recent history of the internet, it’s that seemingly esoteric decisions about software architecture can unleash profound global forces once the technology moves into wider circulation. The true believers behind blockchain platforms like Ethereum argue that a network of distributed trust is one of those advances in software architecture that will prove, in the long run, to have historic significance. That promise has helped fuel the huge jump in cryptocurrency valuations.
But in a way, the Bitcoin bubble may ultimately turn out to be a distraction from the true significance of the blockchain. Once the inspiration for utopian dreams of infinite libraries and global connectivity, the internet has seemingly become, over the past year, a universal scapegoat: the cause of almost every social ill that confronts us. Last year marked the point at which that narrative finally collapsed. Walter Isaacson, Steve Jobs’s biographer, wrote in an essay published a few weeks after Donald Trump was elected president. That remedy is not yet visible in any product that would be intelligible to an ordinary tech consumer. The only blockchain project that has crossed over into mainstream recognition so far is Bitcoin, which is in the middle of a speculative bubble that makes the 1990s internet I.
To some students of modern technological history, the internet’s fall from grace follows an inevitable historical script. Blockchain advocates don’t accept the inevitability of the Cycle. The roots of the internet were in fact more radically open and decentralized than previous information technologies, they argue, and had we managed to stay true to those roots, it could have remained that way. To understand why, it helps to think of the internet as two fundamentally different kinds of systems stacked on top of each other, like layers in an archaeological dig.
One layer is composed of the software protocols that were developed in the 1970s and 1980s and hit critical mass, at least in terms of audience, in the 1990s. In fact, that original openness continues to be all around us, in ways we probably don’t appreciate enough. To see how enormous but also invisible the benefits of such protocols have been, imagine that one of those key standards had not been developed: for instance, the open standard we use for defining our geographic location, GPS. But what if the military had kept GPS out of the public domain? Presumably, sometime in the 1990s, a market signal would have gone out to the innovators of Silicon Valley and other tech hubs, suggesting that consumers were interested in establishing their exact geographic coordinates so that those locations could be projected onto digital maps.
But none of that happened, for a simple reason. Geolocation, like the location of web pages and email addresses and domain names, is a problem we solved with an open protocol. And because it’s a problem we don’t have, we rarely think about how beautifully GPS does work and how many different applications have been built on its foundation. But since we settled on the World Wide Web in the mid-’90s, we’ve adopted very few new open-standard protocols. The biggest problems that technologists tackled after 1995 — many of which revolved around identity, community and payment mechanisms — were left to the private sector to solve. For all their brilliance, the inventors of the open protocols that shaped the internet failed to include some key elements that would later prove critical to the future of online culture.
Perhaps most important, they did not create a secure open standard that established human identity on the network. This turns out to have been a major oversight, because identity is the sort of problem that benefits from one universally recognized solution. Myspace and Friendster, the market settled on what is essentially a proprietary standard for establishing who you are and whom you know. But the thing about the master’s house, in this analogy, is that it’s a duplex. The upper floor has indeed been built with tools that cannot be used to dismantle it. But the open protocols beneath them still have the potential to build something better. One of the most persuasive advocates of an open-protocol revival is Juan Benet, a Mexican-born programmer now living on a suburban side street in Palo Alto, Calif.
That initial flowering was in many ways a logical outgrowth of the internet’s decentralized, open-protocol roots. And partly because the peer-to-peer business models were piracy-driven. Protocol Labs is Benet’s attempt to take up that baton, and its first project is a radical overhaul of the internet’s file system, including the basic scheme we use to address the location of pages on the web. Why did the internet follow the path from open to closed? And yet — as the venture capitalist Chris Dixon points out — there was another factor, too, one that was more technical than financial in nature. Dixon explained while sitting in a conference room at the New York offices of Andreessen Horowitz, where he is a general partner.

From Facebook’s point of view, they’re providing a valuable service to humanity: creating a common social graph for almost everyone on earth. So how can you get meaningful adoption of base-layer protocols in an age when the big tech companies have already attracted billions of users and collectively sit on hundreds of billions of dollars in cash? The first hint of a meaningful challenge to the closed-protocol era arrived in 2008, not long after Zuckerberg opened the first international headquarters for his growing company. Satoshi Nakamoto circulated a paper on a cryptography mailing list.
The paradox about Bitcoin is that it may well turn out to be a genuinely revolutionary breakthrough and at the same time a colossal failure as a currency. As I write, Bitcoin has increased in value by nearly 100,000 percent over the past five years, making a fortune for its early investors but also branding it as a spectacularly unstable payment mechanism. History is replete with stories of new technologies whose initial applications end up having little to do with their eventual use. All the focus on Bitcoin as a payment system may similarly prove to be a distraction, a technological red herring. First, Bitcoin offered a kind of proof that you could create a secure database — the blockchain — scattered across hundreds or thousands of computers, with no single authority controlling and verifying the authenticity of the data.
Second, Nakamoto designed Bitcoin so that the work of maintaining that distributed ledger was itself rewarded with small, increasingly scarce Bitcoin payments. If you dedicated half your computer’s processing cycles to helping the Bitcoin network get its math right — and thus fend off the hackers and scam artists — you received a small sliver of the currency. These two features have now been replicated in dozens of new systems inspired by Bitcoin. One of those systems is Ethereum, proposed in a white paper by Vitalik Buterin when he was just 19. Ethereum does have its currencies, but at its heart Ethereum was designed less to facilitate electronic payments than to allow people to run applications on top of the Ethereum blockchain.
These currencies can be used in clever ways. Juan Benet’s Filecoin system will rely on Ethereum technology and reward users and developers who adopt its IPFS protocol or help maintain the shared database it requires. Protocol Labs is creating its own cryptocurrency, also called Filecoin, and has plans to sell some of those coins on the open market in the coming months. But there is a crucial difference between the two. Speculators can buy in during an I. You go to the arcade, and in the arcade you can use these tokens.
Pseudo or not, the idea of an I. DJ Khaled, Paris Hilton and Floyd Mayweather. In a blog post published in October 2017, Fred Wilson, a founder of Union Square Ventures and an early advocate of the blockchain revolution, thundered against the spread of I. Let’s say, for the sake of argument, that the hype is warranted, and blockchain platforms like Ethereum become a fundamental part of our digital infrastructure. How would a distributed ledger and a token economy somehow challenge one of the tech giants?
The blockchain world proposes something different. Just as GPS gave us a way of discovering and sharing our location, this new protocol would define a simple request: I am here and would like to go there. How would Transit reach critical mass when Uber and Lyft already dominate the ride-sharing market? This is where the tokens come in. Early adopters of Transit would be rewarded with Transit tokens, which could themselves be used to purchase Transit services or be traded on exchanges for traditional currency. As in the Bitcoin model, tokens would be doled out less generously as Transit grew more popular.
As Transit began to take off, it would attract speculators, who would put a monetary price on the token and drive even more interest in the protocol by inflating its value, which in turn would attract more developers, drivers and customers. If the whole system ends up working as its advocates believe, the result is a more competitive but at the same time more equitable marketplace. You’re basically taking that effect and shrinking it down to the size of an application. Even decentralized cryptomovements have their key nodes. The true test of the blockchain will revolve — like so many of the online crises of the past few years — around the problem of identity.
The blockchain evangelists think this entire approach is backward. You should own your digital identity — which could include everything from your date of birth to your friend networks to your purchasing history — and you should be free to lend parts of that identity out to services as you see fit. What would prevent a new blockchain-based identity standard from following Tim Wu’s Cycle, the same one that brought Facebook to such a dominant position? But imagine how that sequence would play out in practice. Someone creates a new protocol to define your social network via Ethereum. Gutterman suggests that the same kind of system could be applied to even more critical forms of identity, like health care data.
The token architecture would give a blockchain-based identity standard an additional edge over closed standards like Facebook’s. As many critics have observed, ordinary users on social-media platforms create almost all the content without compensation, while the companies capture all the economic value from that content through advertising sales. Would that information be more secure in a distributed blockchain than behind the elaborate firewalls of giant corporations like Google or Facebook? In this one respect, the Bitcoin story is actually instructive: It may never be stable enough to function as a currency, but it does offer convincing proof of just how secure a distributed ledger can be. Additional security would come from the decentralized nature of these new identity protocols. In the identity system proposed by Blockstack, the actual information about your identity — your social connections, your purchasing history — could be stored anywhere online. The blockchain would simply provide cryptographically secure keys to unlock that information and share it with other trusted providers.
So much of the blockchain’s architecture is shaped by predictions about how that architecture might be abused once it finds a wider audience. That is part of its charm and its power. The blockchain channels the energy of speculative bubbles by allowing tokens to be shared widely among true supporters of the platform. The blockchain worldview can also sound libertarian in the sense that it proposes nonstate solutions to capitalist excesses like information monopolies. But to believe in the blockchain is not necessarily to oppose regulation, if that regulation is designed with complementary aims. Like the original internet itself, the blockchain is an idea with radical — almost communitarian — possibilities that at the same time has attracted some of the most frivolous and regressive appetites of capitalism.

Yes, the blockchain may seem like the very worst of speculative capitalism right now, and yes, it is demonically challenging to understand. But the beautiful thing about open protocols is that they can be steered in surprising new directions by the people who discover and champion them in their infancy. Right now, the only real hope for a revival of the open-protocol ethos lies in the blockchain. He last wrote for the magazine about the science of communicating with extraterrestrials.

We’re interested in your feedback on this page. We would love to hear from you. Finding the best bitcoin wallet for Android is hard. Luckily for you, today I’ve organized the most popular wallets for Android to make deciding which one to use easier for you.
Large amounts of bitcoins should not be stored on your Android device! If you want the most secure Bitcoin wallet then you will need to use a hardware wallet like the Ledger Nano S or TREZOR. You should always do research before downloading or installing any Bitcoin wallet. Many wallets are malware and will just steal your bitcoins once you fund the wallet. Samourai Wallet is a privacy focused Android Bitcoin wallet.
It is very simple to use, yet packs in powerful privacy features for more advanced users. This makes it a great choice for new users and users with extra needs. Out of all the wallets we’ve tested, breadwallet is by far must user-friendly. It offers basic send and receive features so it’s not confusing for first-time users. There’s no weird Bitcoin terminology although you will need a basic understanding of Bitcoin.
If you are just getting started with Bitcoin it makes a great option! The Mycelium Wallet is a featured-packed wallet that advanced Bitcoin users will love using. It has support for many of the hardware Bitcoin wallets and even offers support for connecting through Tor if you want extra privacy. Airbitz is a great wallet if you are making frequent Bitcoin payments. Fold Integration: This integration allows you to buy Starbucks and Tartet gift cards from within the app.

Bitrefill Integration: You can easily top up your mobile phone from within the wallet! Frequently Asked Questions Any risks if I am using a rooted Android device? Rooted Android devices are more vulnerable to being hacked. Chances are you won’t have any issues running a Bitcoin wallet on a rooted Android, but we still advise against this especially if you are dealing with large amounts of bitcoins. Why can’t I store large amounts of bitcoins on my Android device? Android devices are usually connected to the internet via Wi-Fi or cellular connection. Since internet connected devices are easier to hack, it’s best not to use an Android device for significant amounts of coins.
If you want secure storage, you’ll need to use an offline wallet—also called cold storage—like a hardware wallet or paper wallet. Do hardware wallets work with Android devices? Yes—unlike iOS—Android devices work with hardware wallets. This means you can plug in your hardware wallet to your Android phone with an OTG cable to securely sign transactions with your hardware wallet and broadcast it with your Android device.
Mycelium, Copay, and Greenbits are three wallets that currently work with hardware wallets on Android. Are Android wallets free or paid apps? Hardware wallets are the only Bitcoin wallets that cost money—for now. If someone has access to my phone, can they take my bitcoins?
It depends on what wallet you’re using. Some wallets allow you to set a PIN code so that only you can access the coins. Most of the wallets listed above also encrypt your wallet so that it would be very hard for the average person to access should they have your phone. Still, you should always keep backups and if you do lose your phone, restore the wallet backup onto your new phone or send them to a different wallet.
How do I create a backup of my wallet? Each wallet will walk you through backing up your wallet when you set it up. Most have you write down a 24 word seed that is a backup of your wallet. Can I use more than one wallet at a time? There are no limitations on how many or which wallets you can use. We recommend you download a few wallets, test them out and decide which one you like best!
Are there any wallets that work both on my Android and desktop computer? Yes, but there are not a ton of options. Copay is one of the few wallets that works cross-platform, meaning you could use it on your Android phone and desktop at the same time. All of your transactions would be the same across all of the devices. What’s better about using an Android wallet over a web wallet? I personally receive a few phishing emails a week in my inbox targeting blockchain. These end up in my spam folder, but it’s still a risk that less technical people may accidentally mess up with, which is why apps installed on your device can provide a bit more security.
I only need secure storage, so do I have any use for an Android wallet? If you use a hardware or paper wallet for secure storage of bitcoins, nice job! Having an Android wallet installed on your device still might be helpful. Once you buy bitcoins, it’s always best to get them off the exchange and into your own wallet. So if you can’t access your hardware wallet, you can at least send coins from the exchange to your Android wallet before you get on your desktop computer and send the bitcoins to your paper or hardware wallet. You can always keep a little bit on your wallet to show your friends how Bitcoin works by sending them a small amount! Any risks to be aware of?
While this specific issue has been more of a problem with iOS, know that Google Play Store does not check every wallet that it allows into the store. There have been many apps that were approved by Google that were simply malware and stole any bitcoins that were deposited. Do research on any wallet you download especially if you’re going to use it with significant amounts of money. We do not like to see people have bad experiences with bitcoins, especially since the transactions are irreversible. Also, make sure you are download the correct wallet from the right developer. Not only have there been scam wallets that stole bitcoins, but many of these had the same logo and looked exactly like legitimate wallets.
