Bitcoin mining has received a lot of attention lately.
What Made Bitcoin Mining Worthwhile Before? Mining bitcoins has been a very profitable venture for a very long time. While many people who tried Bitcoin mining failed to profit, didn’t receive their mining rigs due to fraudulent or inept companies, or barely reached a positive ROI on their Bitcoin mining attempts, that was not true for the more experienced miners. FPGAs were the norm, and the rise of ASICs bitcoin mining hardware. These ASICs completely changed the game by increasing the efficiency of mining bitcoins by many orders of magnitude, and completely destroyed the profitability of mining with a traditional computer.

Why Mining Bitcoins With GPUs Was Worth It Until 2013 Before the ASICs, Bitcoin mining was worth it simply because the difficulty stayed quite close to Bitcoin’s price. Many Bitcoin miners were only mining part-time, and were simply using GPUs that they already had purchased for gaming to mine when they were not using their computer. This completely removed the equipment cost from the ROI equation, as the ability to effectively mine bitcoins was just a benefit of having a decent gaming computer. At that time, there were very few huge Bitcoin mining farms. A large portion of the mining community, at that time, were not mining for profit alone. FPGAs began to skew this slightly in 2012, then ASICs shattered it completely.

In early 2013, Jeff Garzik received the first Bitcoin mining ASIC, produced by Avalon. While one other company may have produced a functional BTC mining ASIC around the same time, Avalon was the first to develop, manufacture, and sell these incredible mining rigs to the public. His review of the Avalon ASIC confirmed that not only was Bitcoin mining worth it, but could be incredibly profitable. Performance is much higher than announced.
This Bitcoin miner was mining over 15 BTC per day! Of course, for anyone involved with mining today, 67. Today, one would be lucky to get 0. 0007 BTC per day with that hashrate, according to our Bitcoin mining calculator, and the fact that it used over 600 watts of power, makes operating the machine a losing proposition.
200-400 watts of power when mining bitcoins. For those of you that did not know why Butterfly Labs was so trusted by the Bitcoin community, or did not understand why so many people were willing to pre-order their ASICs, this is why. These machines started a revolution in mining that resulted in the Bitcoin network containing a level of processing power that has never been reached before in human history. Is Bitcoin Mining Worth It In 2018? Yes and no, depending on your situation. The emergence of ASICs created an arms race that made investing in Bitcoin mining machines more volatile, and risky, than Bitcoin itself.
How much electricity does your miner consume? This miner is a solo miner. It has a small chance of mining a block but does not generate monthly revenue. How to Determine Potential Bitcoin Mining Profitability So, that brings us back to the central question of this article. Is Bitcoin mining truly worth it? Over the past year and a half, I would have advised against it, and said no. It did have the potential to be profitable, but it was too much of a gamble.
However, with the availability of 28 nm ASICs, as well as 45 nm ASICs that can be modified to reach nearly the same efficiency as the 28 nms, and the fact that Bitcoin’s difficulty seems to be stabilizing, then Bitcoin mining may be worth it for you. As has always been true, your personal cost of electricity is extremely important. However, this is not nearly as important as it was while Bitcoin mining ASICs were experiencing incredibly fast leaps in efficiency. Now, with a bit of work, and a decently priced machine, even people with average electricity costs can mine bitcoins profitably. Because so many people were burned by a combination of price drops, exponential increases in difficulty, the speed at which Bitcoin ASICs evolved, or delayed delivery of machines, there are an abundance of used 45 and 28 nm ASICs available for sale. The people selling these may live in an area where Bitcoin mining isn’t worth it, for whatever reason, or they may just be tired of it after the roller coaster they have been on for so long. Others may be just trying to hedge their bets, and break even on their investment through a combination of the bitcoins they mined and revenue from the sale.
Examine any potential ways you could utilize renewable energy. This will increase the efficiency of the machines, as processors run more efficiently at cooler temperatures. In warmer areas, this is reversed:-Your BTC miners may end up requiring more power than just the amount consumed by the mining rigs themselves. If it is warm enough for your air conditioner to be running, then it must counteract the heat put out by your machines.
This could be the difference in Bitcoin mining being worth it for you to invest time, and money, into, or not. Bitcoin’s Price Does Impact Bitcoin Mining’s Worth While the Bitcoin mining difficulty is now more likely to fall into a closer relationship with Bitcoin’s price, the link doesn’t guarantee stability. However, it could get out of sync once again. A breakthrough in ASIC technology is unlikely in the near future, but certainly possible. That would create a new jump in difficulty, and render older ASICs less valuable, as Bitcoin’s price should not be impacted very much. Also, as difficulty is only adjusted every 2016 blocks, sharp declines in Bitcoin’s price can make it so that mining is not very cost effective until the difficulty adjusts. A sharp enough Bitcoin price drop could, effectively, cause enough miners to be turned off that it takes a very long time to mine enough blocks to reach the difficulty change.
Bitcoin network could become quite unreliable and chaotic. Still, outside of these scenarios, difficulty should continue to stabilize, and somewhat follow Bitcoin’s price. This means that yes, Bitcoin mining is worth it in many cases. However, whether it is worth it to you is something that only you can decide. Just remember, if you are considering becoming a Bitcoin miner, work through the math before you invest.

So, perhaps now is a good time to evaluate its investment merits and consider whether the recent decline represents a buying opportunity. Before we go there, let’s take a closer look at what Bitcoin is.
Genesis Mining Tutorial Is Bitcoin Cloud Mining Worth It
Before personal computers became mainstream they were mostly owned by hobbyists who assembled them from parts purchased from mail order catalogs. The rudimentary contraptions were good for playing tic-tac-toe and solving simple math problems. They were only modestly functional, they weren’t very practical, and they had no intrinsic value. It is only modestly functional as a means of payment. It’s not a practical store of value. And, it has no inherent value.
Like those old homemade computers, Bitcoin isn’t a great investment. What Makes An Asset A Worthwhile Investment? There are two things that make an asset a good investment. One is an expectation of capital appreciation. The other is an expected future cash flow. There are very few assets that create long-term capital appreciation better than common stocks. Owning a share of stock gives the investor a stake in a company’s net assets and a claim on its future earnings.
As the value of said company improves, so does the equity of the shareholders. For future cash flows there aren’t a whole lot of meaningful alternatives to bonds. Bond are loans made to a company in return for an agreed upon stream of interest income that can be counted on until it matures. That’s why they are the foundation of sound portfolio management. If an asset can provide future profits or future income, then it is rightly a worthwhile investment. Having one Bitcoin today does not entitle you to more Bitcoins in the future, nor does it offer the promise of any future cash flow. It also fails the test of what defines a currency.
Its encryption algorithm and hyper-powerful worldwide virtual network ensures verifiable transaction integrity that is, for all intents and purposes, completely unhackable. But, sadly, that doesn’t make it a currency. A paper currency is a local phenomenon issued by a sovereign nation to standardize its local system of exchange. So, to buy a cup of coffee in Japan a consumer pays in Yen.

In New York the dollar is used. And, for continental Europe, it’s Euros. The only way a traveling consumer can pay for a cup of coffee in any of those places is to convert their native currency into that of the nation where the coffee shop is located. Proponents of Bitcoin claim that it circumvents that system of foreign exchange because it eliminates the middleman and allows consumers anywhere to buy anything from anyone without the hassle or expense of foreign exchange. That might be the case someday, but it certainly isn’t so today. And, while there are lots of places that accept Bitcoin as a form of payment, it isn’t as universally accepted as the Yen, Dollar, or Euro. That, however, doesn’t mean that Bitcoin’s price advances are sustainable.
Bitcoin is not backed by anything and has no intrinsic value. Any one of those could make Bitcoin’s technology obsolete. That’s the whole point of technology. For now, cryptocurrencies are legal in every major economy. It’s illegal in only a handful of places. Some market commentators have suggested that Bitcoin’s recent rout is the result of comments made by regulators in South Korea, Japan, and China about restricting cryptocurrency trading. Others have suggested that may open the regulatory floodgates at the upcoming G20 meeting in March.
The prospects for tighter regulation, or an outright ban on trading, still loom as credible threats to Bitcoin’s price. So, Is Now The Time To Buy Bitcoin? Bitcoin doesn’t have the key components that make traditional equity and fixed income investments worthwhile. So, we would argue that it is a suboptimal asset to build long-term wealth. Its uncertain future makes it more problematic.

The fact that there is no barrier to entry onto the cryptocurrency landscape should be even more troubling to would be investors. For as exciting and encouraging as Bitcoin is as a technology, there is simply too much uncertainty about its investment prospects. There is a lot more risk in Bitcoin than there is opportunity. So and this is not a popular viewpoint these days – the cryptocurrency fails the test of what makes a great investment. There are no macroeconomic fundamentals behind it like there are with the fiat currencies of sovereign nations, such as trade balances, interest rates, or gross domestic product.

One of the cornerstones of this vision is the need for a decentralized, distributed, and pseudonymous currency in order to digitally transmit value from person to person. You cannot truly transfer power into the hands of the people without giving them economic sovereignty, and they cannot have economic sovereignty so long as money and currency are tied to the real world and controlled by monopolistic central banks and governments.
For various reasons, none of these systems have taken off. Bitcoin is a peer-to-peer digital currency. What are some of the properties of good money? Money should be easily divisible into arbitrary units of value in order to handle all sizes of transactions, from the small to the very large. In order to be a reliable store of value, money must stand the test of time. Anything which decays or rots would not be a good choice. One dollar is equivalent to another dollar, and one kilo of gold is identical to another kilo of gold.
Money can then act as a numeraire or measure of value, just like a meter is a measure of distance. The ideal money is one which holds its value and does not steal value through arbitrary inflation and deflation. When it comes to fiat currencies, central banks are supposed to fulfill this role, and when it comes to physical commodities such as gold, this standard is enforced by the laws of the universe. It is physically impossible for someone to conjure up a cubic meter of gold out of thin air, which is why it can preserve its value so well. For something to begin life as money, it should add value in order to seed its own growth.
Gold added value through its beauty and artistic uses, and Bitcoin has the potential to add value through the properties of decentralization, openness, and pseudonymity. I mention openness as the project itself is open source, and the code, protocol, and implementation are all open to scrutiny and analysis. I consider these to be among the most important properties that something needs in order to be accepted as money. It is ideal if the properties of money are inherent in the medium itself, such as with gold.

Gold has all of these properties and more, and this is why it was not only chosen spontaneously by the people across different continents and cultures, but it is also why it has held its value for thousands of years. So far, I’ve explained what money is but I haven’t yet said how this applies to Bitcoin. How can a digital currency possibly be scarce? After all, digital storage and processing power are extremely cheap and getting cheaper by the day.
Bitcoin has employed a novel solution which uses encryption and brute-force power in order to preserve the scarcity of the currency. The graph on the left is a chart of the overall Bitcoin supply over time. Bitcoin has the potential to revolutionize the online payment industry, but furthermore, it could even place economic power back in the hands of the people. Hefty transaction fees currently discourage micropayments, but Bitcoin could completely change that, opening up a whole new micropayment industry in blogging, online gaming, and many other areas. Where to get it Bitcoin can be downloaded from Bitcoin. There are currently clients available for Windows, Mac OS X, and Linux.
If I install this, will this eat up my CPU and share my files? Bitcoin is not filesharing software, so it does not share your files. Can I take my bitcoins to the local bank and get some cash in exchange? I think it’s a little early for that. What you can do though is participate in one of the many exchanges and trade bitcoins for USD, EUR, or other various options.

So, I don’t get it — is the value of a bitcoin determined by the resources expended to produce a bitcoin? Like anything else, the value of a bitcoin is determined solely by supply and demand. If the market value of a bitcoin is higher than the production cost, then it will be worthwhile to devote resources to mining more bitcoins. In this sense, the cost of mining will tend to approximate the value, but it does not drive the value. It is the combination of supply and demand that drives the value. If the value of Bitcoins rise, then isn’t this deflation? I define inflation and deflation as changes in the monetary supply, and it is when we define them in this way that we can see the damage that they cause.
If someone could just conjure up a billion dollars out of thin air and spend it at today’s prices, then they have effectively stolen value from everyone else. Likewise, the deflation that follows an unsustainable credit boom and the ensuing bubble burst can be painful. Ok, so, what can I do with these Bitcoins? The market for Bitcoins is still small, but it is growing every day. You can check out many different services available at the Bitcoin trade page, and you can visit the Bitcoin faucet to get some free coins to get you started. With over 5 million coins in circulation, Bitcoin is currently in a nascent point of growth, and the sky is the limit. Any donations will be graciously accepted.
So, reader, what do you think about emerging digital currencies and Internet technology in general? I believe that nascent technologies such as Bitcoin and its future derivatives have the real potential to drive change and innovation in our world.
