I have participated in a few carefully selected ICOs and have seen incredible gains in value. I only put about 20-25% of my value into ICOs and am very selective. For what it's worth, I am choosing to join the Banco fundraiser and believe it will be a huge win. The service they are providing is invaluable, and the fact that the underlying value of the token inherently increases as other crypto's raise in value means to me that if I am bullish about the market in general, this will be a great place to hold.
Just my thoughts, I am impressed.
Cheers.
