I think bitcoin is very valuable, very profitable for people who are doing business with it .. there are times significant value added. Very high profits are even higher than gold .. but its value is not stable. not safe
It will not be stable if we calculate from monthly profit, just like gold, if we think of investment then the calculation will be equal to gold for one year. Bitcoin trend increases almost 5 times the rise in gold prices, and we need to upgrade about our confidence in bitcoin, maybe a few more years bitcoin will be more equal when compared to real estate, away from gold.
