I just created my first Sell order in Bisq and I’m struggling to understand some things.
During the process, when I was asked to fund my Trade Wallet, there was a popup message which said to ensure that I set a fee of at least 148 sat/byte for the transaction when funding my wallet. I didn’t screenshot this at the time because I thought that the message was self-explanatory, so I can’t remember the exact message.
I sent the requested amount to my Trade Wallet from a BitcoinCore wallet. In the Core client, the fee is entered as sat/kilobyte, so I entered 153600 sat/Kb as the fee (150 * 1024 = 153600).
When I check the transaction which funded my Trade Wallet at blockchain.com, I see that the actual transaction fee in the block was 103 sat/B.
I’m trying to understand the meaning of the original message: why does it matter what fee I use to fund my wallet, so long as the transaction gets mined eventually? Where did the 148 sat/B number come from? Why did the transaction only use 103 sat/B when I specified 153600 sat/KB in the Bitcoin Core client?
Thanks very much for your help,
