Around 10% of my monetary asset is bitcoin because I'm still not earning that much in bitcoin as I just recently discovered that it existed and I have a day job as of now in which I can't save much because of high living expenses and monetary obligations. The smart balance for me would be around 25% of my asset since I need to diversify my investments to other options like stocks,business or properties but depending on the status and value of bitcoin in the future maybe I would increase or decrease the percentage.
