For a currency to be embraced and work you need price stability. Imagine borrowing money in Bitcoin at $100 and paying it back at $20,000. ou also need trust. What happens if your bitcoin gets hacked? There are no barriers to entry? Dogecoin etc.. It is unregulated. It's not a store of value either.. buying Bitcoin at $20,000 and selling at $7,000? As an investment it has no intrinsic value and no margin of safety. Yes it is finite .. but so could the currency of a small emerging nation who legislated not to print anymore money, what would that be worth? No doubt cryptocurrencies will emerge but I think more likely backed by central banks or large international banks. Maybe worth listening to Munger, Buffett, Druckenmiller, Gundlach, Dalio etc...
