But nonetheless, this is not even bad idea :) bitcoin could be made as a real coin, but out of very rare metals, more rare than gold ( maybe platinum?), and in that case , the price would be more stable. You are saying how cryptos are so much better than gold or silver. It can not be, because of its velocity. one day big uprise, next day big dip. people that buy gold, buy it for financial safety. It means, that in case if currency we use, inflates big time or...cryptos crash down....you still got gold. You can exchange gold in every corner . While you can not exchange crypto currencies if exhange services cancel that ability (because they may be just losing money while doing that).... that will never happen to gold or silver.
