Any investment is risky. If you have the ability to repay, you can borrow money.
If you are capable of paying then just save the money and use it for your own investment rather than get a loan from someone. You might compromise the assurance of your paying capacity because your trade could lose.
However, if you do not understand the project, it is not recommended to borrow money to invest.
Whether you also understand it. You have to look at the risk, any amount of risk should be considered by you before taking a loan or much better that you don't.
