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 the price so far of bitcoin was still in declined value, well I guess it is still great to buy now because of its cheap price value.
Now if you can't wait for a long time, day trade is the good idea for us to earn bit of it, though it needs also a bit careful about it. We can earn or can also wreck too if we do the wrong moves.
