But if you "know what you're doing" and quite sure about things, then getting loans and throwing them into encrypted currency isn't always the worst idea. It's how some have made the most money to be honest.
You never know what you are doing when gambling and this was a very bad decision you made.
The mistakes this logic has are too many and go against risk management. In fact this is what degenerate gamblers would do. Take a loan to feed their gambling addiction.
Did it pay you once, then take the money and don't do it again as the risk didn't justify taking a loan. As I read you even gambled with altcoin which is raising the risk even more.
If you still have that money take them out, repay your loan immediately and only hold the profits. Also bet more in Bitcoin as altcoins may be left behind for a while.
