The real estate market seems to be very strong, but now it has reached the end, and there are very few countries that can invest in real estate. They are some new economies, and they belong to third world countries. These countries have certain profits in their housing prices. But I think the cryptocurrency market is more profitable, but both investments are risky.
A person simply writes that this is a real estate business. None of us knows what exactly OP will do and under what conditions everything will pass. Just as we dont know the country and the city where this business will develop.
Therefore, the main task of the OP, in my opinion, to get some insurance. By investing a part of his capital in Bitcoin, and a part in a real business, the author will be able to recover losses in case of failure in one of his business. And by investing all him money in just one thing, there is a high probability of losing everything.
