This industry belongs to the braveheart and the die hard risk takers
there is big difference yet a small distance between taking risks and being stupid!
when it comes to investing, taking risks doesn't mean doing reckless things. it means using your head, analyzing everything, calculate the risks and rewards and then finally take a calculated risk.
what you suggest here is a reckless behavior not a wise choice and it is not risk taking. and it has nothing to do with your title either.
you have to ask yourself this: what if you took a mortgage on your house and bought bitcoin but then price went down and stayed there for a long time or even forever, would you be able to accept a huge loss on the money that wasn't even yours?
