He's most probably pro-crypto.
Are there sources backing this data ?
Atkins was the SEC commissioner for 6 years, and he is a crypto enthusiast. Upon leaving the SEC, he became the co-chairman of the Token Alliance under the Digital Chamber of Commerce and also established Patomak Global Partners, which is a consulting company for both crypto and traditional financial institutions.
If Atkins accept to be the new SEC chairman, it will be a win win for crypto as a crypto enthusiast, but the problem now is that a source closed to him said that he is not ready to leave his company to become the SEC chairman, so I don't know how they will sort this out.
