Yes, I have lost my money in buying bitcoin, but I am trying to recover since the last years, and now, I think I can recover it by slowly. Well, it's not a problem for me because I can try to recover the loss. I am sure that soon when bitcoin price is increased, the loss will be recovered in one-time trade because the profit will be bigger.

Yes, I reinvest in bitcoin after I was losing but I choose to make more than 3 order buy so I can get bitcoin at a low price. And by that, I can try to sell some of bitcoin when the price increase. Maybe that is a scalping trade, and I think that is works for me and I still do that until now. I used the money that I have before to reinvest in bitcoin, but I always search a low price and wait for a while. I cannot still get a low price, but that will be fine because the rate will be increased in the next days so I can sell it to make a profit.
