You are just doing mental gymnastics at this point. Buy any hardware wallet. Most of them use TRNG, which generates seed inside the hardware. It was not the failure of TRNG but instead coldcard coded shitty software where they defaulted the seed generation to PRNG. They are total clowns in the space and all the circle jerks instead of pointing that out are telling us that we did something wrong. If you don’t understand what you’re doing in cryptography, you should probably not do it. Staying retarded helps.
