You borrowed money to invest and you got a good return, you have experience with gambling as well hence you either got lucky or you know what you are doing quite well. However, it's not a good suggestion or advise for individuals who don't really have experience or lack luck to borrow money to invest in any cryptocurrency especially huge money that you can't afford to pay back if things goes sideways.

Let's be careful what we post as there are many newbies here who blindly follows trend seen from experienced traders. The safe word is still 'Don't invest what you can't afford to lose' IMO
