That is a painful experience. Sorry about that friend. I was affected as well and many other. Then I got to realize that Crypto is not a get rich quick scheme and hence needs patience. What I do now is to invest on altcoins the money I know am not gonna need anytime soon so that if my profits aren't coming quick, I don't get bothered I can hodl coin for as long as more than three years now or I don't buy at all if I would be needing capital or profits soon. Experience is the greatest teacher.
