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.
There are some exchanges that allow you to do that but it is difficult to make money that way, have you even mastered making money when the price goes up? If not then it is better to leave shorting alone and to not do it until you learn how to make money like most people do here, you do not mention this in your post but avoiding using leverage is also very important if you are a newbie trader.
