Firstly... you didn't "double spend" in Trezor. Simply spending an unconfirmed UTXO(s) in a new transaction is NOT "double spending". Also, spending UTXOs from unconfirmed transactions is not prohibited... it just means that the 2nd transaction cannot be confirmed until the first one is confirmed. Note that this could actually occur in the same block.

For the record, I've seen "chains" of unconfirmed transactions 25 transactions long! Shocked

As for what is likely to happen to your transactions... eventually the network congestion will ease as the price has dropped a little and stabilised, so there won't be quite the number of transactions taking place as during the big pump. You can see the visualisation of the memory pool here: https://jochen-hoenicke.de/queue/#0,24h

See how the unconfirmed transactions has dropped from 70,000+ to under 20,000?

Likewise, the fee levels have dropped back down to the point where a "1 sat/vbyte" fee is enough to get into a block... so I would expect your transactions to both confirm sometime in the next 6-12 hours (if they haven't already).

Lets assume the mempool doesn't empty and for some reason my transaction fee is not enough, will my transactions be dropped and returned to their original addresses I sent from eventually?  If that make sense.

Thank you so much I was quite worried I would lose the Bitcoin somehow with all the confusion.  I set the fee to 5 sats per byte originally so hopefully a miner finds my transaction worthy of being mined Smiley

I have had a problem with a set of unconfirmed transactions because I had set the fee too low.  I sent all my transactions from multiple accounts legacy and segwit on the trezor to one new account address (segwit) I had made so I can consolidate everything.  I set the fee to low and trezor estimated 20 hours for all 7 transactions on the low setting.  Well 3 days now and nothing, I tried free bitcoin accelerators but I think they are all BS. I read today in reddit somewhere that I could just send from the account that had the money in it as unconfirmed to a new address to myself on the trezor.  So I sent the funds that were unconfirmed in the account that I originally sent to, to a new account on my trezor with a high fee hoping that would work. Well it didn't and now I don't know what is going to happen. Trezor allowed me to spend unconfirmed transactions from my balance which in itself is kinda weird.  Does anyone know what is going to happen to all the original unconfirmed transactions and also the new unconfirmed transaction that I sent to myself?  Thanks in advance guys
