Now when BC is sky high and ETH also pretty high. DO people even give their real money for those currencies. I mean give 300$ for 1ETH or 6000$ for 1BC is too much for most people.
I mean how often do people buy crypto currency like ETH and BC
People buy bitcoins and etherium constantly. After all, you do not have to immediately buy one bitcoin or one etherium. You can buy a piece of bitcoin or etherium. Nobody forbids you to do this.
