If your business can make more money than invest in Bitcoin, why forcing yourself to invest in Bitcoin?
As long as you still have an idea or making your business bigger, there's nothing wrong to re-invest into your business. Invest is when you have idle money, but you don't know or have any time to generate more money.
In as much as he thinks his business can earn him more than investing in Bitcoin. He also feels that whatever he gets from his business as a profit, instead of saving fiat in the bank, where inflation can affect is so much and the value will reduce over time. He prefers to store the value by investing in Bitcoin.
Many people do this and i am not exempted, since i have no use of my fiat and have enough for emergency and to sort my bills, the next thing is to keep putting my money in Bitcoin. However, am not saying if there are other investment i would venture into it, i can do both the investment and still invest in Bitcoin.
You could invest in both of them. Think of it this way, you have a business, and you want to buy the plot of land next to yours, that's a good investment for your business, but not like you can just have money out of thin air, assume that you do not have enough to buy that land just yet, that means you are going to save, and what better way to save than keeping it in bitcoin.
So you have to have 10 million dollars, 2 million in cash and you can get 8 million in loan, but you want to get 5 million in cash and 5 million in loan, you make 1 million per year in savings, that means 5 years. If you invest that 1 million into bitcoin, you can get to 5 million in probably 3 years or maybe less. That is how you use both investing into your business but also investing into bitcoin all at the same time. There are plenty of people I know that does this, they earn income, they invest into bitcoin and when it is high enough they use that to grow their business as well.
