Unfortunately most of the people who were buying at $1,100+ in 2013 sold their coins at $600 later fearing BTC will drop even more. Others sold at $400 and some others at $250. And only a few had the patience to wait until today, and they were damn right.
The thing is that those people wich had jumped into those bubble were looking for easy and fast cash, and the most of them were forced to sell their coins since they thinked it woul get back to 1 dollar or worse, sure those which were able to hold had recover their investment, some of them had traded and invested at lower ammounts, thats what crypto world is about, some loose while others win.
