Bitcoin hashrate surpasses 900M TH/s
Bitcoin network is more secure than ever, as it surpasses 900M TH/s hashrate. The bitcoin mining hardware used for mining also gets more efficient over time. Oftentimes, old hardware becomes irrelevant quickly, in a 5 year span that hardware costs more in electricity to run than the value of the bitcoin it mines.

While it is not possible to mine bitcoin using a GPU, which was totally possible back in 2010, you can still mine other cryptocurrencies and get paid in bitcoin using something like NiceHash. To mine bitcoin, you would need to buy special bitcoin mining equipment that mines SHA algorithms.
In other words, the hashrate also goes up because miners constantly have to change to more efficient hardware to stay competitive. I don’t understand why we even care about a hashrate all time high, it is completely irrelevant.
In case you do not understand these value ranges, keep in mind that the value is not linear with the hashrate and very soon, we will be entering a point where it is worth buying consumer grade mining equipment again. In other words, this is shown on a log scale that is a very basic way of showing data that spans a large range.
