First... the world had barter, but that proved "inconvenient" To replace barter, we had "gold and silver coin standard" as money. Next we had "paper money, backed by gold/silver coin" Then we got "paper money, backed by the full faith and credit" of some goverment issuing it. Now we have cryptos. Backed by nothing... ABSOLUTELY NOTHING... other than hope, greed, and stupidity.... of "players/hopers" with no monetary sense at all. Personally, I'm surprised cryptos have lasted as long as they have*. Ultimately, "going to zero". * That said, wish I'd bought some when BTC was $.06.
