Regardless of how profitable Bitcoin might be, it's not everyone or every company that will want to invest in it. There are various assets that are viable and we shouldn't think that people are financially dumb because they don't want to buy Bitcoin.
That is exactly the point, many of us are BTC investors because we choose to be exposed to its risks and benefits. Because an aseet is a good one doesn't mean all investors would consider it, that's why there are certain investors who choose the real estate market, but they don't want to be exposed to the stock market, it doesn't mean buying shares is bad, neither does it mean they are stupid. There are also other investors who prefer exposure in so many markets, so different individuals and companies, with different strategies.
