Why did FINRA create a crypto hub in 2022?

Could you elaborate on the rationale behind FINRA's decision to establish a crypto hub in 2022? Given the rapid growth and innovation in the cryptocurrency market, was the move a preemptive step to ensure regulatory oversight and investor protection? Did the agency identify specific gaps in its existing regulatory framework that the crypto hub would help address? I'm curious to understand the strategic objectives and expected outcomes of this initiative, as well as the potential challenges and opportunities it presents for the broader financial industry.
