There is not a single person who can answer your question. Investing in ICO's is always risky, in long term(if it's not scam) project has to be successful, so if that project become successful token price will go up.
On side noteI would change topic subject to "why is so easy to scam people"

:
I often see people are investing in Tokens & ICOs.
I have no idea what are tokens & ICOs.
I don't know much about the company
I invested in *add ICO name* and bought 1000 tokens.
