Being greedy while others are fearfull is very very overrated, this applied a few times with cryptocurencies last year, however this year and the market as of now is very different and being greedy while others are fearfull totally dont match the sentiment now, nobody is putting in tons of money in something that gives them losses, how many times were you truly greedy when others wetr fearfull?
Exactly, so as long as the market is not heading into a good direction you will keep losing your money.
I agree with the Warren Buffet quote posted by OP but I totally disagree with what you said about crypto currency investment because no long time investors have ever lost his/her money when invested into Bitcoin when others are fearful. However, I don't know why youvguys believes that every lost in cryptocurrency market cannot be amend.
