I have thousands of trades imported from Pionex.com. All of my Mini Bitcoin (MBTC) and Mini Ethereum (METH) transactions have been priced as Bitcoin and Ethereum wildly inflating my tax liability. There are thousands of transactions (from the auto trading bots) so editing each one manually is not feasible.
This is a Pionex.com export. I used the Koinly trades template to make the import work into Koinly.
I have tried to edit a transaction, but as I stated above, it would be insane to try to edit each individually.
