both chains are vulnerable if a state really wants to f*** with it, sure. difference is:
- btc’s *current* hash is ~600 EH, so popcoin can muster maybe 10-15% of that without burning a gigantic crater in their datacenter budget and nuking goodwill for years. they'd have to *keep* burning money *after* the stunt – hard sell.
- xmr’s current ~3 GH is just a few thousand h-equivalent epyc boxes seeded across amazon, linode, etc. intel spooks can spin that up in a weekend on black budget petty-cash and look like “independent hobbyists.” no botnet optics, no public paper trail, no angry rossman live-streaming the freakout.
is it “proportional”? kinda. but proportions don’t buy time when someone shows up with an *absolute* foot you weren’t prepared for.
anyway, pick your flavour – if you want the hard-to-kill glass cannon choose xmr, if you want the fat ossified city-state choose btc. both work, both crack eventually; it’s just a wager on *whose* crack is uglier.
