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.
Well, for me, I just try to exploit on some loopholes that I see. For example, if there are good coins that are falling in value at one point but has a good chance of climbing back up some time in the near future, I usually invest in them and buy some good amount of it while the value is low. At least, that way, I could get to have a stack of those coins in preparation for the time when its value increases again. Also, in the market today, don't wait for assets to sky-rocket like how it was before because that's not how it works now. As investor, we have to contain ourselves even to small gains, especially when the market is not doing so great because having little gain is still better than having none.
