I heard in stocks, this is called shorting. But i read if you short, you could lose a huge amount of money. Could you do this with bitcoin? Example my thoughts were hey its the holidays, so most likely ppl will withdraw money and thus btc drops. So i figure around now, btc price would drop.
if bitcoin goes down, it might be very difficult for us to make a profit.
because we cannot sell losses, the best possibility is that we cannot sell, we can only buy, or we can look for other coins that still have profit potential and we can infest into many coins.
