What do you mean failures? Failure in trading? Well, if that yes I failed in investing on buying Ripple during the it was 0.00012k sats and now ripple was down below 4k sats if I am not mistaken. And now I learned from my mistake,
if you buy riple with price 12k satoshi and bitcoin price 3k dollar
and and sell riple price 4k satoashi, i think you not big lost money, but big lost bitcoin, in fiat money i think you only few lost money
