Investing in an ICO or IEO in my opinion is still very risky. In two years it has been a lot of failed and even fake projects. Many investors feel deceived because the lost money is taken by the scammers IEO or ICO.
For me investing in Altcoin is already registered on the exchange with a large volume of trades. Buy top altcoins like Ethereum and BNB. For me, these two coins do not have to do some stages of checking, but this altcoin has proved to have good potential in the crypto space.
