Gummo, a former blackhat hacker, claims that he used four supercomputers to mine Bitcoin when the price was just $ 200-300: by then he had accumulated 179,000 BTC.
COMMENT: good. The fears are justified. I disagree on the inexorable future of Bitcoin. If Western Governments wake up they can choose CDBC like ours which has zero environmental costs. it is not greenwashing as many do. It is true green technology. Remember that the block-chain system is a system of false democracy. There are equal conditions between the nodes, but it is like arguing that the Knights Templar were democratic because they shared food and property. Now mining is reserved for a few supercomputer owners. The common citizen who buys cryptocurrencies has infinite possibilities of being scammed, from the Ponzi method to the theft of badly invested money. Combining an anarchist system with a state system is impossible. This is demonstrated by Meta (Facebook) who has given up on launching its cryptocurrency. So we hope that the world will realize the validity of the proposed exhibition of digital currency that respects the canons of the CBDC.hacker
