For me, Investing bitcoin is a big risky as no one is sure what will be the price of bitcoin in the future.
investing in bitcoins is not risky at all in my opinion because it might allow you to make some big profit in the future, besides that i dont think that the price is going to go much lower
A few years ago, it was quite risky to invest in bitcoin. Now it is much less risky. Bitcoin is much more mature.
