A man who helps people with money (Mike Green) says Bitcoin is not good and it's just a bubble. Some big companies like BlackRock, State Street, and Goldman Sachs have different opinions about Bitcoin. Some of them are still trying to figure out if they want to use Bitcoin or not.

- The title is misleading and sensationalist. It implies that Bitcoin is a bubble solely because of the opinion of one portfolio manager, without considering other perspectives or evidence from the market. A more balanced title would be something like "Bitcoin Faces Mixed Reactions From Finance Sector Critics".
- The article focuses on skepticism and criticism, while ignoring positive developments and adoption of Bitcoin by institutions and individuals worldwide. This creates a negative bias and paints an inaccurate picture of the current state of Bitcoin.
- The article cites only one source for the opinion that Bitcoin is an extractive bubble, without providing any data or analysis to support this claim. This makes it seem like a personal attack rather than an informed argument. A more credible approach would be to present multiple viewpoints and back them up with facts and figures.
- The article mentions that other companies have not offered Bitcoin ETFs to their clients, as if this is a sign of resistance or reluctance. However, the lack of ETFs does not necessarily mean that these companies are against Bitcoin or that they think it is a bubble. There may be regulatory, technical, or strategic reasons for not offering ETFs, which are not explored in the article.
- The article ends with a reference to another crypto-related story, without any connection or relevance to the main topic. This suggests that the author is either trying to fill space or divert attention from the lack of substance in the original piece.

- Invest in Bitcoin (BTC) as a long-term hedge against inflation and currency devaluation, with potential for high returns. However, be prepared for volatility and the possibility of losing some or all of your investment due to market fluctuations, regulatory changes, and security breaches.
- Invest in gold (GLD) as a store of value and a diversifier against equity markets, with low or negative correlation to Bitcoin and other risk assets. However, be aware that gold may not keep up with inflation and may lose value in real terms over time, especially if interest rates rise significantly.
- Invest in traditional stocks (SPY) as a source of income and growth, with exposure to the global economy and various sectors. However, be cautious of valuations, market sentiment, and geopolitical risks that may affect your returns and diversification benefits.
- Invest in alternative assets such as real estate (VNQ), private equity, venture capital, or cryptocurrencies (COIN) if you have a high risk tolerance and a long-term vision. However, be aware that these assets may be illiquid, opaque, or subject to fraud, manipulation, or regulatory crackdowns, and may not generate consistent or positive returns over time.
