Mempool was clear last week mining half full blocks.

If you just take a practical approach at this and say there is roughly a 1 to 1.5 BTC fee each block.

We have over $4,000,000 spam fee daily and over a month it's at a low end of $120,000,000.

This will clear like it has in the past. However, like we have seen we will always have these transitions.
