Since what you want to invest is the profit made from your Bitcoin investment. It is a good thing to spread your risk and have more investment from different sources. Real estate is a good choice for you to venture into.
But if there is a chance for Bitcoin to give more profit than any other in a time period then it is better to invest in Bitcoin. We have to think economically as if there is billions of profit in one investment then we do not need to go for other which have profit in thousands. I will favor for Bitcoin investment right now
