You're correct for real estate.

But wait, stock is the same, some people loss and some people earn, because the larger people invest in stock, it will pump the stock price.

I think that you should accept the fact people use Bitcoin more as an investment than as a currency and centralization trying to adopt Bitcoin. You know, Bitcoin is decentralized, decentralized is where no one can control Bitcoin, so it's up to anyone to use Bitcoin for whatever they like and doesn't limit specific people or institution to buy Bitcoin.
