I regret a lot when i did not believe in bitcoin way back 2015 when bitcoin price was just about $200 , I feel like that the opportunity that was given to me was wasted , so right now I am holding some of my coins and let's see if I'm gonna have second chance.
Yes regret by not believing in bitcoin when i first know it, but now i never think what happen yesterday, im focusing now in my collected bitcoin and my investment to ean to have a better way of living.
