From a historical perspective, cryptocurrency is just a highly speculative stage created by humans. Imagine that in 500 years, gold will still be gold. What is the fate of BTC ETH 500 years later, either ignored or replaced. There is a lot of controversy over 10 or 20 years, and if it's a bit longer, there shouldn't be any controversy. If you want to say that in 500 years, btc will be in the same position as gold or replace gold, I can only say that it is not easy for you to be brainwashed and paralyzed like this by his mother force.
