Btc fees

Since inscriptions (and similar projects) the mempool has grown a lot.

Now a lot of it is low sats (330 sats, 294 sats, etc), op_return transactions and also the consolidations of those low sats transactions.

Considering that the hype of those things has waned, fees have gone down, but mempool size has remained big nevertheless.

Question is this: Is it possible that miners are strugling with bills, to the point they want to keep a big mempool (creating it themselves and sharing the correspondent fees) so actual real transactions have to pay a bit more fees (more than 1 sat/vbyte). I mean, in order to keep hashrate?

I consider hashrate a powerful strength indicator, and I believe a sharp drop in hashrate after halving may produce panic in many people/institutions
