Understanding Bitcoin Hash Rate Increases – Bitcoin Magazine

This is an opinion editorial from Alex, a bitcoin miner with Kaboomracks.

It is important that people looking at bitcoin mining for the first time understand the importance of Bitcoin difficulty adjustment, as well as the impact this has on mining profitability. Many newcomers to bitcoin mining will look up the profitability of an ASIC in a mining calculator, expecting that profitability to stay relatively the same in the future. This is a misunderstanding as the profitability of any given machine tends to decline over time. Difficulty increases should be understood before purchasing an ASIC.
