I wondered if the last transaction spike -- with the fee reaching >20 amd even >30 sat/vbyte during some times of the day -- was caused again by Ordinals, Runes or similar stuff. I recently also saw, by chance, a very big accelerated inscription (of several hundred kB).
But it seems not really. While the Runes activity has grown a bit in October compared to September, on the
CryptoKoryo statistics site you can see that the combined share of fees paid by Runes is still lower than 10%, which hints that the space occupied by them is on a similar level. Share of transactions is around 15%.
Observing mempool.space, I also don't really saw that many big consolidation transactions taking place.
Thus, I'm concluding that the activity rise this time is genuine Bitcoin transaction activity. It's not unlikely that it is related to the price increase in the last days. Retailers are returning slowly to get their share of Uptober, perhaps

?
