Trading on margin is even too risky for most people let alone pulling out bank loans or credit cards to trade.
You would think after the dot.com era, people would learn. There were many who got cooked going into debt to finance their trading activities.
There´ll be many more that get cooked on the crypto era. People don´t learn from others mistakes and some unfortunately not even from their own.
I was margin trading before as well but ended doing it with a big loss. Lesson learned!!!
