Firstly how trusted is the platform. And according to what the first comment ask. Do you have the list of altcoins you accept because I have a lot of altcoin some are not even in market yet while some has dropped drastically. So do you accept those that are not listed and those with bad values?
like i said, only admin of the altcoin can contact us. But if the coin is listed and has value, then you can contact us regrading an altcoin.
Thanks
