the question is what if you do not own enough money for investing? can you take a loan and invest?
Because if you look deeply into charts of inflation rates in most the countries you can easily understand taking loans even with high interests could be useful and profitable.
Personally, I don't suggest doing this because using other people's money will put me under stress and this can have negative effects on my decisions. What do you think?
It's similar to taking loans when the price is down and there are many people who do that. While it's not the worst idea in the world, there are a few problems like what would happen if you need to pay the interest and the economy/price goes further down. Also there are times when the expected return is less than that of the due interest and that causes a lot of problems.
According to me, loans must be taken taking into consideration the profits you are going to make with it. Just because there is inflation doesn't sound like a great reason for taking loans. If you have done the calculation and your income will be higher than the interest, then go ahead and take the loan!
