Monero txs are so cheap (usually less than .01 USD) basically nobody worries about it. There was an issue with some network flooding a few months ago where people who needed to get a tx in a block had to up their fee. But that was the first Ive heard of any fee market in years.
That was an attack on dnm… they made $300k stealing from them…
no cap? they were somehow brute forcing privkeys? how did flooding txs steal xmr? which DNM was the target?
