Thats right. but keep in mind that real estate is still much safer because these kind of investments are stable or not volatile compared to bitcoins.
Yet , Much better if we can invest on them both if ever we have a good amount of cash , so that we can still earn on both sides if ever the other one failed us to give a profit.
though in my case i do only invest in bitcoin because i only have a small amount of cash on my pocket but if ever i got a lot of profit from my btc invesments , ill also do try other types of investments such as real estate and others.
