There are two types of crypto users: the peep who wants more privacy and the libertarian. The libertarian makes life harder and worse for the peep who wants more privacy. Libertarians are the ones who over all control the status quo of crypto. Now you have a very good understanding of the issues with crypto the blog post can just end here. You want more details dont you? Ok you greedy bastard who cant use a search engine...
I dont think anyone ever have or ever will create a more fancy way to waste computing power. These mother fuckers buy a bunch of gpus just to overclock them and leave them running at full power until they melt. I once heard a story about the gold miners in old times along the lines of everyone wanted to make money mining gold so they bought all the gear and started looking for gold. Most never found much but reguardless people kept buying gear to go gold mining and because of this the people selling the gear were getting rich while all the miners were just getting poorer. The same happened with crypto mining. Nvidia made a hell ton off selling hardware to mine coins barely anyone uses for anything practical. Sure there are people who do make money mining but those are people who have the money to spend an insane amount on a mining rig in some datacenter in a third world country while they sip their wine in a first world country. It isnt like nvidia is trying to hide it either. Just read this article and get a good laugh in.
This is the main thing most people seem to think crypto is for. People trading it without ever using it to buy and sell anything besides other cryptocurrencies.
