Sometimes you do not have choice. For example, many tokens is possible to sell only on Yobit. It is good that there is a choice of the exchanges in the case of EDC blockhain.
If the asset is only traded on the Yobit exchange, then the choice is obvious: do not trade this asset. This is especially important if trade volumes artificially increase.
And then what to do with such an asset according to yours? Just keep in your wallet and wait a few years?
