My worst bitcoin decision Ive ever made when I wasted my bitcoin into gambling, hyip and double site. Because when Im new in bitcoin I become addicted playing dice games, joining in any double site. And, turns out all into scam that I lose all my money.
I regret that too but it was an accident when I did invested to HYIP because I didn't know that they are just scams. And when that happened I was still new to bitcoin and I haven't thought that there would be scam like that which are existing in real life.
