Because bitcoin prices are falling, that's the reason you have to buy bitcoin now, if you want to make a good profit a few days or weeks later then now is the right time to buy bitcoin. Do your best then the results will not disappoint you.
The price will fall and some will panic, then it's a good opportunity for us to buy cheap bitcoins so we sell it at a profit when the price will back up.
It will happen most of the time and every time I see some dumps I am also collecting coins to stock because I know it would give me easy profit.
