I'm using Ethplorer to check my wallets and track my tokens if the token I waited coming from bounties have finally arrive in my wallets, I have so many shit tokens in my wallet that are sitting in my wallets for years but I notice that some coins do not have value in Ethplorer whereas in Etherscan they have value, did you also notice that, which of the two are you using to check your wallet.
I think if the accuracy of the information, then both are the same, because Etherscan or Ethplorer comes from the same source, MyEtherWallet. But to detect exchanges, it is easier to use Etherscan.
