Cryptocurrencies have helped lots of people in Third World countries survive hyperinflation. At one time it was illegal to buy dollars in Venezuela and even Argentina. I'll never understand people who blindly hate cryptos. They seem to lack real life experience. If it's the energy used, the problem is already solved. The Euro has lost 90% of its value relative to gold since its creation but people don't notice it because they haven't experienced hyperinflation. We shouldn't trust the government when it comes to money. A decentralized privacy-oriented currency is actually a good idea.
