However, insider information can also be false. It is possible that you will be deliberately misled. It is also possible that the source of the insider information was (in turn) misled. In any case, you can get into a very dangerous situation. If your venture fails, you will not be able to repay the loan and pay the accrued interest.
The bank is very cruel to debtors. It passes the receivables to collectors. Collectors take all measures to collect the debt from the debtor.
In my opinion, the only situation where a bank loan is justified is the purchase of real estate. Real estate is a very expensive asset. It is difficult to buy property without a mortgage.
There is no guarantee whether insider information is correct or not, then why taking risk of loan. Bansk AFAIK does'nt approve loans for gambling, obviously you will give some wrong info to get your loan approved. Banks are never in loss they have something in there hand which you pledge againest your loan. Take loan for safe investments like real estate as you mentioned.
