it seriously baffles me that in this present age and time people are still making such terrible decisions, even as technologies has made knowledge and information very easy to get in what ever field you which as long as it being utilized, and someone is still making such a terrible decision financially.
I believe that the first rule to every trade or investment is using an amount of money you can afford to lose, so taking a loan just to trade or invest is actually a terrible decision in my own point of view, because it certainly a money you can't afford to lose, so because of that it puts you under unnecessary pressure just to meet up and pay back the money that was borrowed, and in this crypto industry being in a hurry or inpatient will only leads to severe losses if care is not taken, so just as what the op has rightfully said, the market is actually not running, opportunities are always there in the market, so it's best to trade or invest with your own funds than using a borrowed money.
It's humanity, we always make stupid decisions, we all do. Sure maybe not this one exactly but if you look at every human, you will see that all of them made a mistake, and if they are too young maybe they haven't but will make one in the end. Sometimes we laugh at it later on when we realize how terrible it is, but the reality is that we are not going to see this changing too much, we should know that it's going to be something that will take some time but we will get there, we can't really consider this any bigger.
We know how hard this is, and we know how terrible it would be if we are not careful as well, so we do our best. If it's about taking a loan and putting it all on bitcoin, I can say that I avoided by an inch many times, I always wanted to do it too lol.
