It is reasonable to have different investment. How long and short. At the same time need to develop their investments in coins.
I prefer to choose long term investment. We all know that in business you can't have directly double or get your investment. You will pass first the path of trial and error. If many will approved or like it so they will proceed to their business. In bitcoin its better to have long term investment because its value goes higher so there is possibility that your money will double.
