I think burnin is still handling the chips himself. CryptX only is doing the shopsystem things. And maybe the hardware for the bitfurys too. But the assembly of bitburner is burnins part.

Looks like yifu put in 16 chips less than 10k... 8320 in the 2 whole boxes. 1680 should be in the rest. But its 4 plates full with 13x32 chips = 416 x 4 plates = 1664. And there was a tray with 13 chips. I think thats 16 chips missing...

Still not reached burnin so i think ill travel to him anyway. I counted the chips he needs and can bring them to him.

Sorry to hear what happened dude, but I wouldn't let a stranger use your pc, especially plug anything into your computer. As for encryption, use a random string as a password like 534jgkhfgSDFGergf34£%$&%egfs so it would be hard to brute force or dictionary attack.
