The first six months of 2017 the top 30 grew with 1200%, in the same period Bitcoin grew with 200%. Explains why this project makes sense
Diversification of risks. Bitcoin, like other coins, also falls well, as it grows.

Or do you mean something else?
No. What I'm trying to say is that the mentioned 30 coins are worth much more than bitcoin. You just need not stick to bitcoin. I think it is very sensible to diversification of risks
