Finally passed the 0.1 BTC milestone, but feeling some transfer anxiety

I just bought the dip and officially crossed the 0.1 BTC mark. It’s been a long journey of stacking sats, and it feels incredible to finally hit this milestone.

Now that my stack is growing, I know I need to get my coins off the exchanges. I’ve had a Trezor Model T sitting in its box for months, but I haven't set it up yet. I’m feeling a bit of transfer anxiety. I’m terrified of making a mistake during the process and losing my hard-earned BTC.

I’ve also seen some talk about the Model T not being as secure as newer models.

For those of you who have been through this:

Is the Model T still considered solid for a 0.1 BTC stack, or should I upgrade before moving?

What are your best tips for a first-time hardware wallet user to ensure I don't mess up the transfer?

I’m planning to do a small test transaction first, but any advice to calm the nerves would be much appreciated!
