**Describe the problem:**  
I had not noticed before. I have a very tiny amount of leftover Link but it shows the “average cost per link” as NZ $758.47 ? that is not correct , link never got that high, maybe around $60 USD.

**Which exchange/wallet is this regarding?**  
Dont know, it appears in the Koinly calculation. Cant pinpoint it to any exchange or wallet.  
I have gone over the trades I have done with Link and they all look fine.

**How did you import data into this wallet?**  
API and CSV

**What have you tried to fix this so far?**  
Gone over old trades and compared values and transactions, nothing is missing or unaccounted for. It does not make sense as a average cost. All my other Koinly calculations look fine.

Try turning on “Treat transfer fees as disposals” in settings. When you have a very small number of coins, the Average cost can get skewed. Have a look at your most recent LINK transactions instead to see the cost base that was assigned to those.
