The data shows that if the value of ERC-20 tokens is stored, the volume of coins, fire coins and OKex ranks in the top three.

Cryptographer Christian Ott said on Twitter recently that it is not convincing to rank cryptocurrency exchanges based on transaction volume due to the existence of cleaning transactions. Ranked according to the value of the ERC-20 token in its address (excluding its own exchange token).
