Hi everyone, any help on this matter will be greatly appreciated.

Context - I'm an expat living in the Netherlands. Yes, I am an American citizen.

I bought some crypto from my Dutch Cypto.com account (in Euros) over 12 months ago and it has done pretty well for me. I now want to cash out but instead of selling it out and transferring back to my Dutch bank in euros, I want to send the crypto to my US Coinbase account and then cash out to my US banks (in US Dollars).

I'm not sure how taxes would work on this, given that Coinbase will not be able to give a date for purchase... as these bitcoins are transferred.

I'm not even sure if this is a smart way to do it, or should I be selling it via crypto.com in the Netherlands and just using a money transfer like Wise to transfer the euros to usd?

Again, any help would be greatly appreciated!
