It is not wise to borrow money in any business. All businesses may face losses. Even if the business loses, you will have to repay your loan. It can even be a financial burden for you if you can't afford it. And you don't just have to make up for the loss, you must make a very good profit in the business because you have to pay interest on the borrowed money as well as your own profit. Imagine for a second what will you do if your investment goes into a lose.
