Why XC, not DRK, MRO or something that will come out with much better anon tech? you seem pretty confident in one horse, don't get too confident. If anything is certain in crypto it's change.
Im also gonna go out on a limb and say if things really go to hell like you describe, guns, ammo, food and fuel will be priority 1. No one is gonna give a shit about crypto when their main concerns are survival.
You just said everything I was thinking.
