The Bitcoin network recognizes the work that miners do, as they play a very important role, rewarding them for creating new blocks. The way they are rewarded is for creating a new block of 6.25 BTC from May 2020. This price is scheduled to drop to half about every 4 years.
By 2040 the block reward will have been reduced to less than 0.2 BTC and only 80,000 Bitcoins out of 21 million will be left. Only after 2140 will mining end with the mining of the last BTC.
Although the fact of reducing the reward for blocks does not aim for a great future for miners, the Bitcoin community is quite supportive of this and does not intend to phase out the mining process as was done on Ethereum.
Although mining is a competitive business, getting started is easy. In the early years of Bitcoin, anyone who knew what Bitcoin was could simply download a piece of software to their computer and get started.
The first thing to start mining is to buy an IC device commonly referred to as ASIC.
These devices can only mine Bitcoin but are quite efficient at this. They are so efficient that their introduction in 2013 made all other types of mining computing devices obsolete almost overnight.
Mining with a CPU, GPU is not possible on Bitcoin except in other currencies as they do it at such a slow pace that it is just a waste of time and electricity. Specifically, the best available graphics card just before the rise of ASIC, AMD 7970 produced 800 million hashes per second. An average ASIC today produces 100 trillion hashes per second that is 125,000 times over.
An important factor in buying a mining device is electricity consumption measured in watts. As in two devices that produce the same hashes better is the one that consumes less electricity. Before analyzing which device is best suited for your needs, it is important to understand the factors that affect your mining profits.
