can anyone recommend an app to do crypto taxes? I tried Koinly, but they're not able to assess NFT value in the past. How do you guys handle taxes in Switzerland?

My « challenge » is NFTs as most of the tax tools I’ve tried are not able to value them and therefore put a value of 0. I don’t think it’s entirely correct. 

I’m assuming CoinGecko shows flood price right?

What is your challenge with crypto taxes in Switzerland?
You simply report your holdings at year-end as part of your assets. 
For this, I look at my Coingecko portfolio at year-end.
