I have some q.s.
1. When we have ico token, What do we do with them? How to sell them into money?
2. Few campaigns have their own wallet? How to sell them in to money?
From some of my experiences. If I have a token I save and I collect up to a lot. Then I sell it if the token is registered in the coin market.
Usually every project campaign they have their own wallet address and you can sell it to a market that provides token sales.
I hope this helps.
