You can consider yourself a strategic person if you are not going all in with bitcoin amidst all these opinions given by different persons. You can never be certain about bitcoin's future so as a precautionary measure, it would be best if you would invest on fiat too while investing on bitcoin at the same time. Even though our generation is telling us that bitcoin is our future, just by the fact that its volatility is great, you can never be sure on what may happen in the future in terms of your investment with bitcoin.
