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?
Difinetly no exchange firm like charitable institution because this is part of crypto business which money is involve in every transaction so maybe there's a minimal payments but maybe it runs very slow in terms of transactions processing.
