I have tried exchanging USDC to BTC using Changelly and the Trade tab in my Trezor.
The transaction failed
Sorry, your transaction failed or was rejected. Your coins have not been exchanged.
But if I go to my account I can still see an unconfirmed tx. I have tried sending some USDC to another address and they are unconfirmed as well (and I can’t find the tx in ethscan).
Gas price is fine I guess.
Is it stuck?
