It is very clearly seen that most of the reviews of bitcointalk users negatively relate to investments in ico companies and this is correct, because many of them lost their funds because of this. But there can be exceptions only if the investor is really familiar with the new project and has full confidence in the integrity of the development team and in the prospects of this project.
so basically it is difficult for newcomer investors to enter this industry because the investment is not so clear they will make, for that reason then of course investing in ICO will no longer be recommended because the risk is too large and also returns are very worrying for them so it would be better to invest in the top coins in CMC
