Petro uses the hash X11 algorithm. It also uses the PoS (Proof of Stake) and PoW (Proof of Work) algorithms for protection.So is it mineable?
If it uses X11 then it should be, though it might just be vaporware for all anybody knows.
it looks like Petro can't be mineable, because it's a combination of those who use the POS and POW algorithms, but it's better to ask one of the Petro Teams here, hopefully your answer will be helped
