Not every rich people made returns from their every investments, I read somewhere the best ever and most successful investor of all time who is Warren Buffett even have the success rate of 6 or 7 out of 10 means you can still lose no matter how good your investment plan is. Never borrow money to invest, just make money and start investing. Life is simple but don't complicate it with things which you can't actually control.
Borrowing money to invest I think it's like gambling and it's really not recommended,
need really mature consideration to make that decision and it's not easy for sure,
investing still has risks so if we borrow money for it I think it only makes the risk bigger
Borrowing with a high interest rate will certainly make us very quickly debilitated physically and mentally when the profit has not yet come, but the interest from the loan has jammed our mind and lost the mood to work every day, therefore, to avoid such mental terror, it is better to borrow at low or almost zero interest rates. And there is no need to be averse to borrowing money, investing is also one of the purposes of making the future promising, the purpose is not to borrow money to play, equating with gambling is too much subjective judgment.
It is always risky to borrow money as you said it has fallen us into the metal pressure and we loose the working ability .However some of us always like to take risk but i always think about them if they loose on his prediction he might loose his/her everything .I always support to invest on crypto cause it has real future for sure ,on the other hand always also tell to ignore borrowing money .You may invest what you have ,it will not make you to feel risky if you loose you can recover by taking loan or borrowing money but if you do it initially you may loose everything .I think gambling is also a stressful way to earn ,its true you can get huge return from here but you can also loose what you have .So better to take minimum risk and make your fund to invest like this .
