And I highly advise caution with TokenTax. I chose them because I had ~2k transactions on Deribit, and they promised they can digest them. They don't give out refunds specifically because their website claims they will work with you until you're satisfied.

Well, it was clear from the 5th minute they don't have "Deribit support", and I had many email exchanges with them spelling out in detail how their engine misunderstands my transactions (cost basis etc.). I gave them every opportunity to improve, and instead they eventually just ghosted me.

I understand it may be unrealistic to expect they will build this capability in three weeks. It's a shame they weren't able to level with me, and talk about the complexity of this. I ended up writing a taxable gains calculator for Deribit myself and would be happy to share it with them.
