It's risky no doubt but if you're looking at those as long-term investments, you should be good. Also, even though things have been looking as the market was at the bottom since spring (and it turned out there is even deeper bottom, and then even a couple more bottoms), it's a good idea to invest into icos when market is near the bottom. So now seems the perfect time Just wait for the new cycle (hopefully it comes sooner rather than later), try to spot the top and sell. It's smart to sell, and then rebuy lower if you really believe in project.
