Until now, after the price go up high yesterday, I have sold half of the bitcoins I have, it has made me very profitable, the other half Im just waiting, maybe the price has go up than yesterday, because Im not good to reading the market, so I better hold on for a while until the price rises even higher. Not yet 10 years, I have known bitcoin, maybe 2-3 years ago, that has been make profitable and has brought many changes to my life, from being able to find my own pocket money ,investing and studying other digital currencies. yes of course, if I know bitcoin in 10 years, I will be more advanced, by making bitcoin a livelihood, for example short-term trading.
