Bittrex deposits and withdrawals

Describe the problem: how do we down/upload them??

Which exchange/wallet is this regarding?

How did you import data into this wallet?

What have you tried to fix this so far?

You can request these files from their support team.

Alternatively, create a csv file using the Koinly import format and enter the deposits/withdrawals manually.

When Bittrex sends me the deposit and withdrawal history, how do I add it to my existing Bittrex file uploads so it integrates/calculates properly?

Ok thank you, I will try that.
