supposedly secp256k1 is "insecure" *cough* yes that's why bitcoin's got the highest market cap

check out safecurves... there is a big margin of opinion in cryptographic security that needs to be understood

lukechampine is a cryptographer i respect for his brutal honesty about his opinions about things, after reading his great piece on CSPRNGs

bruce schneier is also great but the dude has been compromised by the woke crowd and he is biased against bitcoin so anything he might say against sha256 or secp256k1 needs to be taken with a grain of salt

there is a fashion for a few years now that edwards twisted curves are "superior" to other types of elliptic curves, and BLS12-381 is very popular with shitcoiners

but, being that neither of these two targets even taken as a mass represent a worthy cryptanalysis attack target worth studying, or that most such crappy people who would try to do things like this are usually a bit retarded

my opinion is that if sha256 was weak and secp256k1 was weak then why is it still secure?
