Bitcoin is no doubt risky investment, but it depends on people, bitcoin is opportunity to some and challenge to some. I think you should not borrow money to buy bitcoin.
True, if you want to increase your profit then you must be ready to take some risks and exert more effort than the usual buy and hold. For me it is both opportunity and a challenge because at first it is an opportunity but later on you will find yourself challenged by these different opportunities on how you can maximize your chances of success.
