> It seems the entire decision of using secp256k1 was made to avoid secp256r1. This is another piece of evidence that Satoshi Nakamoto must have beee active in the 1990-2000 cypherpunk community, so that he was well-aware of those discussions. This should shed some light on his possible identity.

I was well aware of all that, at the time and now, without being active in the cypherpunk community. Granted, I was in college for a CS and math degree, but the cypherpunk community was pretty loud if you were listening at all.
