I have some tokens which i gained from joining airdrops and bounties. Some of them have their value showing in Ethplorer.io and some dont.
Is there anything i can do to see a token's value (like for instance Brickblock (BBK), which is on coinmarketcap)? Or is there anything the token issuer could do to arrange this? Or is there nothing we can do and we just have to wait?
Try to use Etherscan (not Ethplorer.io). If your coins are listed on coinmarketcap then you will see their values through Etherscan.
This is because Etherscan accepts only price info from CMC (Coinmarketcap).
