Guys, I've been reading this crazy stuff posted by someone called "Shelby Moore" (whose messages were recently re-posted in the WO thread by user THX 1138), about how all coins held in SegWit addresses will be donated to miners, as they are free-to-spend coins in the legacy (pre-SegWit) blockchain, and only the coins held in legacy addresses will stay intact and belonging to their owners (private key holders).
It
is technically possible. Indisputably.
Is it likely? Who knows?
Then again, we've been discussing this possibility (i.e., sounding this alarm) since before segwit activated. It ain't new knowledge. Well, Shelby's affixing a date to it is more recent. But this vulnerability has been known from the beginning.
Me? Yes, I do worry about it. OTOH, less than 1% of my BTC has any segwit anywhere in their current or past. And this possibility is but one reason for this.
