People do use loans for all kinds of reasons, and they do not necessarily rely on a gullible friend/relative to give them preferential terms. We have an over indebted society, and part of the reason is that debt is cheap and it also reflects various ways that the dollar (and other fiats) has been undermined through the years and even debased through the issuance of debt.
Just because the debt system is a bad system for society, rich people use debt to their advantage, and getting cheap debt can frequently allow for way more money to be made, as long as you know how to use debt in a way that you are finding higher returns on your money and that you are not putting yourself into a place in which you are not able to pay back the loan and/or that you might even put collateral into jeopardy if you are not using the debt in profitable and prudent ways.
Debt will only be encouraging to me is if the person plan to make use of that money properly like to start up a business with high chances of being successful over time , or maybe for life and death situation , but collecting loan for investment is not encouraging because you are only making use of money you can hold for long and
there are chances you be in haste to sell off that investment inorder to pay back the loan , might even lose it because some tend to gamble instead of investing looking for ways to have quick returns like investing in some shit projects.
You are getting the whole point here wrong, taking a loan to invest in bitcoin is not a bad idea if you are paying from another source, because the outcome of your bitcoin investment has no role in your ability to pay back the loan, and
the rich mostly takestaking a loan
are meant to leverage on an opportunity, not from the place of lack.
If you are taking the loan with the hopes of paying it back from your investment, then your investment is doomed for failure because it's a wrong idea entirely.
