Essentially the designers of cryptocurrencies like bitcoin had to ‘solve’ the problem of limiting the amount of coins in order to preserve their value. They came up with the worst possible solution to implement the so-called proof work by wasting energy.
The more coins there are, the more one energy one has to waste to mine another one, exponentially! So all you have to do to get rich is to mindlessly waste ever more precious electricity in data centers. The more the planet suffers, the richer the miners get.
Blackrock owns energy grids (and is buying more) and secret locations of cryptocurrency mines in the US, while the middle class foots the bill. There are too many Dems helping them.
