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?
LoL, today is not any exchanger give free fee in their service, even that deentralized exhange still needed fee for pay the miner for handling your transaction, but if yu want sell without fee you must sell you altcoin directly to someone
That's merely impossible to happen mate, every exchanges need funds to operate their trading activity. I don't think that's 100% sure, and maybe it's a shor term promotion by new exchanges. Just trade your coins to legit exchanges, you might be dealing with scammers if you entrust it with unknown sources.
