As Entrepreneurs we get into various business transactions. And consideration must be considered. Having the characteristics of money especially paper money, what's stopping you from accepting Bitcoin for your business transactions?
The main reason is that Bitcoin is still not accepted or legalized as an alternative means of payment. Some countries still prohibit Bitcoin, some do not have issues with owning Bitcoin, but do not allow its use as a means of payment.
If countries legalize the use of Bitcoin for transactions, I am sure that the number of people choosing to use Bitcoin over fiat for their businesses will increase, especially those who are constrained by distance and currency differences.
