Coinbase is the largest crypto exchange in the world, located in the US. You also have an option in Binance, but you have to make sure that you are not on a list that includes about a dozen states whose residents cannot open an account there.
-Must issue private keys so I can store on Nano X
You can't import private keys in Nano X, the hardware wallet doesn't work that way. Buy coins, send them in transaction to Nano X.
-No nonsense approval/verification process
Forget that you don’t have to run KYC on a centralized crypto exchange, it’s a thing of the past. For such things you have to go in the direction of decentralized crypto exchanges, and since I've never used any, I can't recommend a specific name - but for information, there's a list
here.
Thanks so much for your help. Forgive my ignorance but I just want to be able to transfer any crypto I buy to my Nano X and vice versa back to the exchange to trade or take profits. I was under the impression that in order to do that, you needed to have your private keys issued to you first but I understand now, that’s not correct. With that, I just need an exchange where I’m able. And does that also mean that I have to use an additional 3rd party wallet to do that or do all exchanges allow you to transfer to a hardware wallet or only some do? Thank you kindly again
