my wondering question is why these wealthy people have suddenly become interested in Bitcoin and other cryptocurrencies, usually, they want to invest in real-world businesses but now they have a change of heart I think they have discovered something about the future potential of the crypto industry that's why they are flooding into the crypto industry nowadays.
In talking about the sudden interest from institutional investors and prominent/wealthy individuals, I'd definitely bring the pandemic into the picture, I think Bitcoin's resistant to the negative effect of the pandemic made quite a lot of people believe in the network, do their research and decided to make Bitcoin a hedge to handle fiat devaluation and the inflation impact.
Another thing you need to understand is that this individuals still have quite a lot of Investments outside of Bitcoin, but since they have experienced some of the good qualities inherent in the network, they'd be losing absolutely nothing putting a fraction of their wealth into investing in Bitcoin.
