choosing both of them in my opinion is the right choice so you will get 2 income and I did that until now, because investment in crypto doesn't require much time
And that is why this question should not even be asked.
Investing in cryptocurrencies will not take that much time as the price changes quickly over time. Businesses require a lot of things especially time, money, knowledge or skills and especially the effort you need to exert in order to make it a successful business. Business requires time, Bitcoin doesn't require much time, you can just combine them to make a good way to earn money.
