Can you please explain further how this has affected your cost basis? And with “not recognized by the API”, do you mean you believe these transactions should have been Swaps?
This was an assumption on my part. The root of the issue is that I have some bitcoin for which the cost basis is unknown. Looking back at my transactions, it appears that I bought the bitcoin with after having swapped my Tether for BUSD (during the tether FUD back in March). Otherwise I can’t explain why there is no cost basis for the bitcoin (which I sold). Every exchange and wallet I have ever used is linked via API to Koinly.
The error message on Binance mentioned that swaps can’t be tracked with API. I assumed that converting USDT to BUSD would be considered a swap, I I’m thinking this is the root of my missing cost basis.
