Haha, yes, there's a lot of people who possibly got even richer than those people who got rich out of Bitcoin. Not just from STEEM but think about how many other crypto's there are. Bitconnect is one where people got crazy rich too.
See the thing is.. I'm sure Bitcoin can't be printed like FIAT money can.. but what if you made an altcoin that works like a money printing machine, and just use that to buy Bitcoin and other stuff with? if you keep the market cap low, who will notice? And when everybody on the platform also wins, who will complain?
Not sure if this is happening to STEEM but it very well might happen to other alts.. There are some strange things going on in the crypto world for sure :)
I love it though.. so much excitement! Crypto is better than any HBO television show! Game of Thrones eat your heart out!
