What kind of notice could/would/will we expect?
I've got coins spread across various devices, forms of storage etc. I don't fancy being left with a load of shitcoins (whichever becomes the defeated chain).
Acid rain, dogs eating cats...chaos everywhere.

Entire towns being washed away
Favelas exploding on inflammable spillways
Lynch-mobs, death squads, babies being born without brains
The mad heat and the relentless rains
