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.
As of now, you can still see the price of Bitcoin a bit low than what it was the previous years. So in order for you to earn from it, you should learn to trade different altcoins and do some timing trades. Buy low price tokens with high volume then sell it when it rises in price. Even for a bit by bit of a profit, at least you are not on the lossing end of this current drops.
