The current bubble in the ICO market is very large. I always feel that way, so I don't think I should invest in the ICO project at present.
When you invest in an ICO project, it's a gamble, and the odds of losing money are high.
Not too big,total marketcap of cryptocurrencies is stil less than 1% of the total market cap of gold,so there are still room to grow.Though there still no certain future of cryptocurrencies i still believe that it could replace the fiat in the neart future,either way we would still be rich because we are the early adopters.
