I've just gone back to the sidelines as the mempool is not the only thing with anomalies right now. If you look at btc and most of the altcoin market, there was a huge drain of liquidity/liquidity grab market wide. Some alts/tokens dumped around 50% in just a matter of minutes...only for AMM'S to recover the price, but liquidating longs and stripping the book of its strength.
I am curious to see how the Mempool flood and the liquidity grab effects the market over this next week or so. This could effect sentiment quickly.
Also, there have been mempoool floods before, most recently around the time that Ordinals were new (earlier in the year). It costs money to spam the chain, so the attack will have to stop eventually.
