News: Bitcoin experienced significant volatility on Friday, falling below $47,000 after failing to hold gains above $48,000. This price action, coupled with a Bank of America warning about a potential stock market bubble and the negative premium on Grayscale trusts, suggests short-term bearish pressure. However, long-term bullish catalysts remain strong, with the approval of the first North American Bitcoin ETF and Tesla's significant investment continuing to drive institutional adoption and legitimacy.

Market Probabilities: 
Bull 40% | Base 40% | Bear 20%

Recommendations: 
Short-term: HOLD
Long-term: BUY
