I found one of those blocks yesterday by accident. I knew like 4.7 BTC fee in one block was a lot, but I didn't know how to find which transaction caused it (and I didn't want to go through it manually).
I notice something interesting:
two transactions with 4 Bitcoin fee, within 29 seconds apart. And one of them is included 10 blocks later than the other.In other words: does a higher fee really help for a faster transaction? What were those miners thinking skipping this one for so long?
I always believed a higher fee would give a higher priority, but apparently even 4 Bitcoin fee gives no guarantee to be included in the next few blocks!
Good catch! The miners should really check whether the software they are using really prioritizes transactions based on fees, because ignoing such 4
BTC fee transaction for so long is simply scandal.
Miners often using their custom software for mining, so does not need to be necessary Bitcoin Core issue.
