third point, no. the everlasting question of inflation bugs means that monero can never be a truly reliable store of value, because it's not a hard currency - for all we know it could be 10% or 30% more in supply than anyone knows

don't tell me otherwise because there is NO WAY TO KNOW after the damn coinbase, unless you are telling me that monero devs have broken elliptic curve cryptography *cough*

technical hard fact

sorry, not sorry

but the other two points are correct, signing a transaction is literally an elliptic curve, usually ECDSA but now can be a wonky version of Schnorr, this is plain old cryptography, i can walk you through how to code one in Go in an hour

second point is correct, yes, and this is a big problem, backdoored hardware and firmwares, and is why we all need to agitate and amplify all the efforts being made to make auditable hardware and firmware

second point keeps me up at night and makes me wish i could just throw my mobile phone in a wood chipper and never have another one again

and damn you all, i will have a VoIP phone in the near future, running open source firmware... and no damn radio "wireless" fucking boomers
