How do you know if PubKey prefix = 02?
I think it's a waste of time to guess whether it's 02 or 03 prefix. Whatever the script is, it must pass all the private keys. It is impossible to accelerate this way. It can be filtered, but filtering is not acceleration.
That's right, that's the limit. It can speed up by about 6.3%. If spin rotation is used. I don’t know what can be optimized in the GPU anymore. Everything is clear there. This is absolutely a normal increase in speed. Every percent is worth it, especially in GPUs.
