Ric Edelman, a well-known Bitcoin advocate, continues to advise investors to allocate 10% to 40% of their portfolios to cryptocurrencies, even as Bitcoin's price falls below $90,000. Edelman sees the current market conditions as a buying opportunity for long-term investors, highlighting factors such as institutional adoption and regulatory clarity as positive indicators. Edelman points to Harvard University's $116 million investment in the BlackRock iShares Bitcoin Trust and the increasing integration of blockchain technology by Fortune 500 companies as evidence of growing mainstream acceptance. He remains optimistic about Bitcoin's future, predicting its market capitalization could soar to $19 trillion, representing a 955% increase from its current level.
