I believe that traders who have no trading experience for more than 10 years should not use credit money to buy assets. I had a very sad experience in 2018.

That's the worst decision to be done by unexperienced traders. In fact when you were using the loan to buy assets and it's just like putting your life into your project. There was a huge chance for such a project to be a failed project.
That is something you have to consider, if you really a good trader then borrow atleast some amount you make a gamble in trading and let's see how it goes, once it gets successful then used it again for another trade. You don't necessarily need to put all your money into once, you have to be wise in making your trade moves.
