I'm not going to say they are the wealthiest if they just hold 1 BTC. However, if an individual replicates the actions of these large companies, it is highly likely to be successful. The character of the investor matters the most. Investing is not just about buying a lot of bitcoin, but it is also about how we manage it. This is a high-risk investment, and we can't deny the fact that it is just like in business, where risk-takers get higher rewards than a normal investor.
