Are high fees a part of this healthy network dynamic from which perspective you have declared the hash/capability of said mystery miners to be suspect?
Do you support or have interest in low fees on the (shorter) SegWit chain? For anyone, I would be curious to know your interest on high vs low fees.
Please disclose for all to see.
I just got away with moving 1.5 BTC for a little over 27000 sats on the other chain, and it was confirmed the very next block. (I probably overpaid.)If you are paying more than that on the other chain, at this time, you either are not paying attention or are moving the coins away from a third party who hasn't bothered adjusting the fee they charge you to withdraw.
Look at this transaction that just went through on the other chain. 192 sats
