As there are hundreds of new ICO's every week but unfortunately most of them are scams atleast more than 30% of new ICO's are scam and if things go like this then people will lose trust on ICO. Kindly help me with your suggestions about filtering scammers.
I find that over 70% of ICOs are scam. So that is why investors become scared and do not continue to invest in ICOs. In addition, the bad market makes investors lose money and they can't invest in this period 2018 is a bad year for the ICO, but the ICO will not die now. If the market recovers in 2019, we see ICO growth like 2017
The future of ICO...

base on the market preview of all who participated on ICO only a 50-60% remains in the market, yes, we seen the 30 - 50% are either Scam, or useless ICO as posted on the trading market, they did not have a good marketing strategy, unclear platform, white paper are not attractive to the consumer's, that's why some of it did not event have a good market support after it was launch in the market. No taker or buyer and have limited investor.
