It's pretty disappointing that some people don't understand how
BTC works, I will show you a great example of how someone could lose a lot of money just because they don't understand the basics of the asset they invest in.
This guy
created a transaction right after block 821856 was mined, he set 648 sat /Vbyte ($30) as his fees even though 387 sat/ Vbyte is almost guaranteed to get him into the next block 821857 (has not been mined yet at the time of writing this), but that is fine, if I was rushing and fees are unstable I might have done the same thing if I had no way to replace the transaction, although he had that option but anyway.
Here starts the misery:
A few seconds later he RBFed the transaction with
1116 satNo confirmation yet? let's pay more to confirm the transaction
A few seconds later he RBFed the transaction to
1,293**As am typing this Foundry saved that guy and mined block 821857
He kept raising his fees every few seconds till he stopped (more so till the transaction was confirmed)at
8125 sat/ Vbyte, he was lucky enough that Foundry didn't [1]see the last transaction and ended up adding the one prior to it which was broadcasted a few seconds earlier, which paid
7,895 sat /VbyteSo, long story short, he paid $367 when he could easily get away with $30. All he had to do was understand that his transaction needed to be in a block. Blocks take time to happen, and always watching the mempool status to gauge the bidding is crucial. Paying fees without checking the market is like blindly bidding on something without considering other bidders—you might just outbid yourself for no reason.
[1]. It's possible that Foundry received it, but the block template was already generated, and they found the block before they could reconstruct the new blocktemplate. But yeah, that saved him $10.
