Koinly automatically assumes $0 cost basis if there's no history of acquisition of an asset (there's a "missing purchase history" error showing).
While we recommend "clearing" such errors, it's not needed. It's only so that you don't have negative balances of such tokens, which is often confusing for users.
Do mind that such errors often indicate that you didn't yet import your full transaction history, and fixing this root cause is the preferred solution.

On the problematic Trade transaction, click the three dots (...) → Duplicate.
On the duplicate:Change the Type to "Deposit" (or "Receive" if Deposit isn't available).
Set the Worth field to 0.00.
Save.
Go back to the original Trade → three dots → Ignore (or delete it).
Go to Tax Reports → Recalculate.
****Is this really what I have to go through to change each transaction to register a 0 cost basis? I honestly want my money back.
