Selling or swapping?

Hi,

Let’s say one of my coins on Trezor does a 10x—right now I have $2,000 there, so it would become $20,000. What’s the best way to manage a large amount like this?

I’m not sure what the next steps would be. Should I sell directly from Trezor? Should I swap it to a stablecoin using Trezor? I know that in my country, selling crypto before holding it for a year triggers taxes, so ideally I’d want to avoid that. Would swapping to a stablecoin and holding it count as selling?

Or is it better to send the funds to an exchange like Binance and then sell or swap there?

I’d appreciate any tips. I just want to avoid costly mistakes and minimize fees where possible. Thanks!
