You know what you are not alone... We cant truly predict what will happen that's why we are here to take a risk... Investing is too risky sometimes we didn't know if the strategy we are doing is the best or not... That's the reason why as for i am just holding my coins because as for today the market is not stable... We will loss so much if we didn't think carefully... But dont loss hope it is not the end continue working and soon it your coins will come back again...
Actually when you summarized it, you don't lost anything, as long as you don't do selling in low price you are not loosing your coin.. Its the market value actually lost, the market price drops and it affect our investment, but when you check it your coin is still the same its actually the value of it is loosing. Wait for it to grow and you will see that you will gain your profit again.
