Since so many ICOs seem to be getting done privately by big institutions investors where the public needs to have connections to get in to a large minimum investment (Eg. 100 ETH+)...
Do you think Public Pre-Sales (e.g. minimum 100 ETH) or Pre-Sale Pools will even exist in 2 years?
I do not know for sure whether they will or will not, but if there is a lot of manipulation, as now, then most likely, it will stop. After all, people will not already believe in it and will not give their money to such projects.
ICO will exist longer that what you expect, But there will be changes on this.
Most of ICO in the future are those businesses in FIAT with ongoing business and as the adoption in cryptocurrency, they will make their own step to be better.
One of the businesses that vanish was KODAK and now they want a rebound and taking an ICO now that they expect to lift their business again.
I believe that it may take too long but I couldn't make sure if it would lasts but I'll always hope that the ICO will have a brighter future ahead of it and besides if this would happen everyone here in the crypto market are one of the beneficiaries of the improved and development of the cryptocurrency market.
