Hey everyone, stupid mistake from a newbie and I just can't figure out what to do. I bought BTC through Swan, then bought a Trezor, downloaded Samourai (this was a while back), moved everything from Swan's custody to the Samourai wallet and then finally to the Trezor generated address for cold storage. Pretty sure I did everything right at the time. The idea was for longer term hodling but now I'm looking to dip into and spend some of it. Samourai has been seized so I downloaded Mycelium but I'm not sure what to do now. At first I entered in the passphrase to restore a backup wallet which was from the Samourai wallet I used, and it shows in the transaction history where I sent BTC to the cold storage address, but now I'm looking at that public key with my money in it wondering how to move it to the Mycelium wallet address. I believe I read that to spend it I would have to send it to a hot wallet and then send what I want to spend to that person and then the remaining balance back to myself at a newly generated Trezor address. I have the twelve word passphrase to the Trezor that I thought is supposed to hold the keys to the address I generated with the device, but it's been so long since I used it I can't figure out how to make it all work again. The Trezor Suite lite when hooked up to the trezor model T shows me nothing in the dashboard although I thought it would show the balance associated with the address the device generated. I'm so confused. Any help please!

Restoring Samurai's seedphrase shouldn't do anything if the funds were sent to the address generated by Trezor wallet. From my understanding that's what you did, right? you linked your trezor device to Samurai's wallet?

But since you're saying you tried using Trezor Suite Lite (which is nothing but a watch-only wallet for trezor) is still not showing you any balance, I'm starting to think that the wallet you sent the funds to, may not be the Trezor device. Have you checked the generated addresses?

So the funds you sent end up in your Trezor wallet but you can't able to see your balance with Trezor Suite.

In the first place, how did you generate the Trezor receiving address?
You should use the same software that you generated the Trezor BTC address.

Or try to use Electrum wallet and connect your Trezor and let's see if it shows your balance.

Either cold or hot wallet, you can send your bitcoin to other people, addresses. If with cold wallet, you can not send your bitcoin, it sucks and nobody use cold wallet.

Your question reveals something wrong in your understanding too. If you can send your bitcoin to a hot wallet, you can send it to any receiver. It's an on chain transaction and it's spending.

and then send what I want to spend to that person and then the remaining balance back to myself at a newly generated Trezor address.

If there is leftover of your bitcoin from UTXOs you choose for a transaction, you will receive it in a same address or in a change address. Change address is recommended because it helps your privacy and anonymity a little bit.
