I want the opinion of you members of this forum,
whether to use capital from bank loans unsecured and risky if used trading by traders who have good skills? even though in my opinion
safe as long as we can make a profit and smoothly repay loan installments to the bank.
Your friend is not a gambler and he understands that taking a loan from a bank is like going to the devil for a cup of water. Nothing from the devil is ever free of charge. There are always hidden charges. Your friend should continue in his record of winning trades and sooner than later he will have the big break he desires.
