Jim Bianco, President and Macro Strategist of Bianco Research, expressed dissatisfaction with the launch of a Bitcoin spot ETF, calling it "a huge mistake". He highly praised the prospects of decentralized finance (DeFi) as an alternative in the financial field. Jim Bianco also pointed out that spot ETF products can bring higher prices for Bitcoin, but will not reach the $1 million predicted by PlanB, creator of the Bitcoin S2F model.
