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.
There is no system that can ever be free of scam, sooner than later, these crowd funding means will still count their own scam too, they must surely be dared by these scammers. The only thing that will make STO own different is that they can easily be caught which still guarantee smart scammers wont doesnt get away even though their identity is known.
We still need ICO and what we need to do for ICO is to be its security, starting from bounty hunters, most especially, bounty managers, we should only promote trusted and verified projects, there is no method Binance is using for their IEO that project managers too cannot use before engaging bounty hunters, all it requires is a very thorough research to be done.
