Busta Rhymes (a.k.a. Trevor Smith Jr.) tweeted this morning that he is “officially holding Bitcoin,” saying that he made the decision “after watching the Bitcoin conference live” featuring Dorsey, Musk, and ARK Invest co-founder, CEO, and CIO Cathie Wood. The conference he’s referring to is The B Word, a streaming event held yesterday by Square, ARK, and venture capital firm Paradigm.
