So if I buy Combicoin, my performance is related to the performance of Top 30 coins? But why would I want to do that if I could just as easily spread all my holdings into the top 30 coins? Yes, it may be that I become loaded with burdens of maintaining wallets, but then if I did Top 30, I could exit from the best performing ones and realize profit, while holding onto the others.

I feel it is a good concept, but the risk of Combicoin running away with my money seems too large. Plus, how do we know for sure they invest in top 30 coins and not extra coins we do not know about? Good idea but I need more convincing.
