It is true that if you take a huge risk then your profits can be very significant, no one is denying that, but what will happen if for some reason we invest in the wrong coin or at the wrong time in the market then you are going to lose everything that you have and I'm sure that is not something that you want, after all we know that even if you invest in the right cryptocurrency like bitcoin if you do it at the wrong time as many of those that invested when it was at its all time high you could need to spend years just holding your coins to recover your money.
