Instead of planning to use your business money to invest in bitcoin, I advise you to use the profit to invest and keep the capital to run di business and even di profit no be all you go use because you get other bills and things to do.
the first question is, is that profit you are making from your business your leftover money (Discretionary income)? Investing in Bitcoin is suppose to be done with your leftover money after you must have settled your basic needs and expenses and not with the profit your generating from your business. So from that little money you are generating as profis from your business you pay your bills and you settle your basic needs and expenses. Then if there is any leftover money, that is the money you will use to invest in bitcoin and also build up your emergency fund and backup fund.
