Cost Basis-
The cost basis per unit for my FTM tokens is showing as £0.49, which is incorrect. Based on my transaction history:
- List item
On May 31, 2021, I purchased 5,000 FTM for £1,109.92 (~£0.22 per unit).
- List item
On October 22, 2021, I sold 4,995 FTM for £9,198.44 (~£1.84 per unit).
- List item
Later on the same day (October 22, 2021), I repurchased 5,017 FTM for £9,220.46 (~£1.81 per unit).
Given this, my cost basis should reflect the £9,220.46 purchase, as I had sold off the previous holdings entirely before buying back in. However, Koinly is calculating the cost basis at £0.49 per unit, which is incorrect and will lead to the system reporting a larger unrealized gain than I actually have.
This discrepancy could result in Koinly overstating my taxable gains until my holdings exceed £9,220.46.
