it depends - are you ready to long-term investments (for example you have already work, and just searching for extra money)
Than you going to think how much can you afford to invest (if it 100-500 - I can suggest ICO - they are doing interesting product to solve some market problems, and they are interested in growing of the product fatures and promotions - so their token going to grow)
Than you should analyze the market - do not enter the scam project  - and most time nobody ask you just transer your money directly into the wallets, they creating webpage etc
Check the team, check the product! Go ahead
But trading - always acomplish with researching
Good luck
