Let's not think of it that way. View it on the positive side, think of those people who only rely on Bitcoin with not have enough information about real estate investment. The same as me who didn't know anything about it until I realized and learned about it. Maybe they can see Bitcoin as a much better investment than real estate, but the time will come they will know that both are good investments.
The way I view it is that investment is investment, just be smart in doing the one you choose to engage in. If I were anyone, I prefer engaging in the two of them, this is the smartest way instead of comparing the two. This is a good means to diversify your portfolio and I do not see a good investor that will do otherwise. It is good to avoid putting our eggs in one basket, and Bitcoin as you see it, is a seasonal investment, it is not the best investment as people think. Couple with the fact that it is an online investment, everything is virtual and anything can happen at any time. We should plan better instead of giving kudos to one over the other.
You should know that the real estate business is physical and very practical, I love it, and if luck visits you in it, you can earn your 5 times profits easily from it depending on the location, the time dedicated to it and how good you are at it. However, what I advise people to do is to invest their sold Bitcoin during the bear season of the coin to avoid letting the funds be idle. Or you will still invest in Bitcoin when you are fully aware that it is selling in the long-term disposition during the bearish season? I guess no is the answer. This is the time you even use the money to make more money so that you can buy it back at a lower price when you either believe it will bottom or confirm a viable bullish trend after the bearish phase must have ended.
The smartest indeed only if you are knowledgeable about these two kinds of investment. That is when we will know and appreciate the importance of diversification of our investment but the thing is, it is also a risky type of investment if the investor does not have enough knowledge in any one of them and has decided to invest both because he knows diversification should be a thing.
