My biggest mistake was to hold for so long. Now they were all stolen(, and the remaining 4BTC wallet identifier is lost). But I DON*T GIVE A FUCK.
Lol I think it's not a problem to store bitcoin in a long time. Because that would be beneficial as a long-term investment. Your problem is on the security of your wallet
Yes, long-term storage can bring much more profit due to the constant price increase, and this is only good.
