worst decision ? there were so many, specially on gambling. youll wagered more than you profit. and those cloud mining sucks a lot on you and others.. ive wasted enough btc on those. haha. but still youll learn from that.
gambling is risky,lest bitcoin depleted because of gambling,because of gambling we rigged it so bad
if you lose at gambling was not a bad decision, because it's a habit you gamble and hope to get lucky. My worst decision was to put investment in cloud mining and HYIP. but it was a few years ago, and now realize that it was a bad decision, because I have invested in large amount there.
