First, let's look at the information about all the past BTC Halvings.
Bitcoin mining hardware first moved from the CPU to the GPU, and then to the FPGA and ASIC, but the proof-of-work principle remained the same. Over the years, technological improvements have made hashing a very efficient operation, consuming only 0.03 joules per billion hashes (with specially designed specialized integrated circuits, ASICs, etc.). This has reduced the cost of energy per hash by about thirty thousand times over the past 10 years. However, miners on the Bitcoin network are currently calculating hashes per day more than 10 orders of magnitude higher than the 2010 level.
At the same time, the network complexity, which has been steadily increasing since the zero block, as well as the hashrate of BTC itself, indicate an increase in the number of enabled mining equipment.
Thus, we have several prerequisites for a serious growth of BTC in the next 5 years, and, accordingly, the growth of mining as an industry:
Thus, the most stable and investment-attractive activity for a private investor, in the context of the cryptocurrency industry, was and remains Bitcoin mining. Only a BTC mining can afford stable, constantly increasing earnings at a distance. At the same time, altcoin mining is very volatile and often promises the owner to encounter often unfair conditions(sometimes bordering on fraudulent schemes, we will talk about this in subsequent articles), and can be recommended solely for reasons of speculative earnings. While Bitcoin mining has remained profitable and fair over the past 12 years, and the above data allows us to predict that the growth of the industry=returns will continue.
