if a miner minted a block today that had 1 segwit-like TX in it, i seriously doubt that block would be valid.
It would be valid, of course. Perhaps you should consider posting less and studying more? -- not trying to insult, but without the basics you're wasting people's time.
i'd love to pick your brain and ask you questions
like "so why is it you are shooting for 95% hashing power before activating segwit?" but you're busy, and I dont want to disturb you
so I talk with poeple here for answers....
but you're right i should read up more and then i'd be the one schooling other poeple here.
