The BTC mempool never rises above 90 MB, but transactions with low fees keep disappearing. Are they deleted from the mempool by the miners? Is this how the miners want to keep the mempool constant?
Yes they are being dropped. I think it was change made at the previous ath backlog.
Wow. So now you can make a TX whose fee is over 1 sat/byte but is dropped instantly/not forwarded because it's lower than the lowest fee on the full mempool, instead of in 2 weeks.
