We have a lot of scam in the crypto market and a lot of investors are realizing this already this is why the ICO market is already going down and will still continue to go down until every one move to a better method of crowdfunding which includes IEO or STOs which are regulated by trusted body, though it is possible for scam to come to the IEO market but it would be so easy to detect because this scams can only be carried out by new exchanges.
