You got it wrong, it's the mining hash rate and not the nodes that counts. You also got the math wrong: 10,000 + 5,001 = 15,001 which is closer to 33% than 50%. There are currently 11,302 Bitcoin nodes and 1,315 Btrash nodes, don't pretend less nodes is better.

Then we have the hash rate, same algorithms are used. Bitcoin hash rate is now: 151.20 EH/s while Btrash is at 1.8 EH/s. It'll cost CIA 84 times more to interfere with Bitcoin than it would cost them to interfere with Btrash.

All in all, the hardware for taking over Btrash would cost you $43,920,000 and you'll need space and cooling for 16,363 devices plus about 20MW of energy supply. Meanwhile for Bitcoin you'd need: $3,689,280,000 for the hardware, 1,393,232 devices and 1.39GW of energy.

Not to mention that if CIA started to build something like that, it wouldn't go unnoticed and more people around the world would increase their own mining operations to prevent a 51% attack which is essentially only good for delaying on chain transactions anyway. This isn't really a big issue since Bitcoin now has off chain transactions while Btrash still does everything on chain.

Face it, not even China could do this, they did try it, remember all those coal plants they built, their massive mining facilities, how horrible they treated their workers and all of that, and still they failed. CIA has no chance.

Let's also not forget that a centralized operation would be extremely vulnerable if say a truck loaded with bombs would roll into the massive warehouse where they set everything up.
