SBI Holdings’ president and CEO, Yoshitaka Kitao, commented on choosing Bitcoin Cash:

"The vision of the original Bitcoin white paper written by Satoshi Nakamoto calls for a peer-to-peer electronic cash system. That is a powerful vision, and SBI Group will devote resources to enable a future world where Bitcoin Cash is used globally for daily payments. SBI Group will acquire cryptocurrency share through mining, in order to stabilize the market. Presence of a cryptocurrency “stable shareholder” will stabilize the market."
