I think OP is referring to "Real Estate" and not just "Property". Then if it's real estate, I would say it's the best investment. Real estate is a better vehicle for building wealth compared to the other two. The reason is simple, Bitcoin is a risky investment because it's extremely volatile, while Gold, as Warren Buffett has sagely noted, "though gold may be the oddest commodity, it doesn't always glitter as a good investment", and say further, "it isn't even really an investment like stocks or bonds, but some kind of different entity. It's not useful and it doesn't generate any kind of income."
