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
Naturally they do it. If you spend fiat money for the crypto that will grow in future, you can get much profit (in virtual or fiat - just make your choice).
