It’s surely a positive effect. Not only because bank will purchase crypto as part of the retirement plan but also crypto specifically Bitcoin is already on the euphoria phase which means any positive news that will give a potential huge impact will surely boost confidence to retail and institutional to purchase more for early position.

I believe this is a good move in case will approved specifically on Bitcoin because it’s proven that Bitcoin price grow long term which is perfect for retirement plan rather than store money in bank with peanuts interest.
