I think investors are aware of scams because it involve large some of their money for the trust on the project. Investment is risky because many fraud living along the internet which become the utility of other people to gain huge many in easiest way they think. Unsuccessful project is other one why it is risky to invest because sometimes even it has good paper, it has some problem. You have to invest on real potential coin than choosing new profit.
yes, of course, experienced investors do not carelessly place their money on an ICO project that is not yet clear or successful.In fact there are currently a number of ICO projects that have managed to raise funds from investors, and after the funds have been collected, then they run away to bring investors' money. Nothing can guarantee the security of investors' money in the ICO project. Is it possible to involve a trusted third party as an escrow agent for depositing investors' funds in an ICO project? So, if the project fails, the investors' money remains safe and can return to investors.
