I agree to your thought because as they say do not put your egg in one basket. For me, it is not bad you invest maybe 60% to 80% of your money in bitcoin but make sure that the 20% that will remain can still save your financial expenses. Every investment is a risk and that is what business is. The bigger that risk you make the bigger return you can take. We just have to study very well the thing we will invest to before investing in it
