okay, the first investment that you are doing now is already good, because investment in ethereum,
and for ICO, ICO is a kind of coin that wants to realeas, and the price is still very cheap, usually we get a bonus amount of 5-25% bonus of additional coins from each purchase.
it's just a danger, ICO can be a SCAM, and the money we invest will be lost if the project is SCAM.
if you want those who can advise, you can sell your eth, and replace it with cheap coins that have the potential, such as cardano, tron, ripple, maybe doge, etc.
hopefully can help you.
