The exact same addresses are assigned the exact same value of BTC in the genesis block of the new chain. So the exact same keys own the exact same coins (equivalently: the set of unspent transaction outputs is identical). LMK if that doesn’t answer your questions.
In the future, why would everyone else want to resurrect that chain tho? if other ppl don’t buy into it (and make a new chain or w/e) then it’ll just be the old-guard amongst themselves. IMO that wouldn’t end up with much value.
Other ppl do have a reason to buy-in to bitcoin today: it’s the most secure chain. That goes away with a discontinuity. (Not to mention that mining rewards would be super low relative to adoption if you rebooted a dead bitcoin)
Good to know. I have kept my comments just to bitcoin atm – like ether (ETH) can be seen as a commodity, unlike BTC. so WRT the current discussion it seems like other chains should be discussed separately (tho we can make some generalizations like LTC is basically BTC wrt reasoning about its value as money).
