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.
We will always think about our profit so we will choose that investment category which offer us more profit. If business is offering someone huge return and there is no associated risk then it's okay to not put money into bitcoin because just wealthy people can carry out two investment at a same time otherwise its not easy because one has to complete his family needs. Bitcoin is more competent asset and will never see defeat because it is used from years but permanent decline never occurs in its price.
If one can afford double investment then there will be no better thing for enhancing your economy but try to save some amount for emergency purpose as we should be ready for each kind of circumstances. It can also be possible to continue a business and utilise some amount of profit from a successful business into bitcoin investment so your money will not only save but will also continuesly increase.
