I would only put half of my money into bitcoin, because I do still need fiat more in my everyday expenses, and because can't be use in any stores here in the real world, so it would be wise not to invest all of your money into bitcoin, since fiat is the one that we still needed the most, and I would invest my money only to bitcoin because if I am going to invest it as a capital for a Trading for example, it will be hard for me to predict and always checking if it is the right time to buy and sell coins, too many things that you need to do in Trading.

Unlike if you are going to invest your money into bitcoin, all you have to do is to wait for the right time to convert some of your bitcoins from time to time to have profits in the long run.
