Note: In SPOT trading, you can never lose your coin, the worth of your coin can only reduce but your coin remains to rise again in worth when the market goes green.
Aren't you also getting a coin in the future trading? But instead of getting it today you will get it at a future point in time. If prices drop then you make a loss because you could buy the coin cheaper at the spot market instead of from the future contract. For me holding a losing coin is not a bad idea. If you don't need the money right away and don't have a better alternative to invest in, why not just hold the coin for a few month.
