A friend of mine who taught me bitcoin, now he feels his disappointment for not holding his bitcoin until now. And now my friend is holding bitcoin out of his income, but I think everyone has been dumped in ATH 2013. maybe if holding his bitcoin now it's become a millionaire
I think not to be disappointed because as long as we can still look for it and when it is getting back from that decision we have to do hold or sell .. your friends experience just like me so I've never felt it and now I have bitcoin savings for the future
