There are many altcoins today, is there any way I can exchange them for free. Changelly charges a lot, other exchange services too. Most of the excahgnes do not have the token I want.
Any service that provides the same?
If you don't want to use an exchange due to the high fees, then use a local Escrow group in your area. You have to be careful though with your trade in such group as some criminals can disappear with your money or coins.
