Not all the ICOs are scams. Many of them have a good idea or aimed at solving the problems that BTC or ETH have. We need to look thoroughly at the 10% that are left
I think more than 10% because I see there are still many ICO projects that can reach Hardcap, there are still many ico projects when the redemption is opened directly into coinmarketcap. That shows the level of investor confidence that is still there, a sense of optimism from investors
There will still be ICOs come 2019, so I cannot say we might see any serious reduction, although, the excitement with ICO last year cannot be compared to the excitement this year, and there is no way we could have imagined if this is something that could be applicable to the trend of the market, or we are generally just seeing the years of ICO reducing.
Nonetheless, if we are to look at IPOs, we will see that new companies arise every time and we get to see the investors still popping in, which I feel would be the same case with ICOs over time and for the fact that eventually the space may get regulated.
I agree with you, in 2019 IOO will survive and be attracted by investors, only natural selection will occur to select a good and decent ico project to invest.
