As long as you keep investing and your money is in circulation, then you don't really loose, just cashing out profits to make more profits, you can always come back in before some good news with twice that money - that's my opinion.
Regarding digibyte - I think it has a bright future ahead of it, and, if the devs are going to meet their targets, in a few months it can go up a lot IMHO. I'm expecting the first spike this month due to the new protocol release, but I think the real pump is going to happen when digibyte gaming goes live.
