  If you’re not using a cold wallet and doing the transaction signing completely offline, then you’re trusting Microsoft/etc not to steal your keys. It’s not just you who could have access to the keys if your keys are stored on an Internet-connected device somewhere that can have its software updated.

    Well in use Intel CPU their management engine could steal your keys from RAM as you are making a transaction. So unless you build your own computer you are trusting someome somewhere

      What good will the management engine stealing my keys be to Intel or anyone if I never even put the computer I’m using to sign transactions or generate the public key online? The signed transaction can be transferred manually in hexadecimal to an internet-connected computer which broadcasts the transaction (but never sees the private key ever). Secondly, you can use computer hardware from before even the invention of Bitcoin, and then code the software on that hardware, developing the libraries yourself. Third, you can use computers simple enough that it’s not feasible to hide any management engine trickery in it. Fourth, yes, you CAN actually build your own computer, which I’m trying to do. :) But to further your point, I still haven’t proven to myself the argument that the elliptic curve used by Bitcoin hasn’t been intentionally compromised like the NIST curves were. I take the word of the Internet for granted there... But I suppose I could prove that myself.
