About adding more coins to bitmax.io exchange. Its true they got just a few coins listed and these are mainly the top coins on CMC, but they don't look to be in a rush to add up coins and somehow that is good. There're are no medal for exchanges with the most coins, most top exchanges add a few coins and they're careful when doing so. that way you don't need to delist these coins after some time.
BTW the team should give the procedure for list a coin.
