I think there must be a security agency that oversees the ICO, where each ICO must go through verification first before raising funds for investors, if the ICO cannot be verified then it can be ascertained that the ICO that is run is illegal. I hope there will be an institution like this, if there really is anyone who wants to make a security company like this, I am ready to become an investor, because I am concerned about investors who are cheated investors
We can do nothing because you cannot find the scam projects and when you come to know about the credibility of a project, they have taken all the money. The best thing we should do is to invest our money only in big and reliable currencies like bitcoin; Ethereum, Litecoin, ripple and some others top currencies in the list. Never invest in new ICOs. Your money will be safe.
