This depends on your attack surface. There is a guideline to avoid writing your own crypto. This is because side-channel attacks are a thing. Your implementation cannot use more or less power/time when any bit of the key is correct vs incorrect. Well, this can also applies to bit pairs, and bit tuples.
But if you don't care and just want money, sure, just use whatever cores are out there. You're probably going to assume crypto solves other problems that it doesn't and your product will just be "secure-ish" and any issue will be not your problem.
In short, real crypto is weird. advertisement-crypto is easy.
