Describe the problem:
I’m in the process of generating a report for my 2025 year taxes. I bought some BTC in 2023 from an exchange and moved to Trezor wallet and sold via Kraken in 2025. Now I see the report stating that is a short term capital gain. I noticed that when I moved the BTC to Trezor is stating in Koinly that is missing the purchase history. How do I fix this issue.
Which exchange/wallet is this regarding?
Trezo to Kraken
How did you import data into this wallet?
API
What have you tried to fix this so far? Yes.
Hi @SC_Guilamo
First, make sure you have added all your wallets, including the exchange where you purchased the tokens, Trezor, and Kraken.
if you see missing purchase history errors, it means the data imported into the wallet is not complete - refer to this guide.
