The Indian banking system, as with all other countries' banking systems, is definitely faulty. Everybody knows that, but is Bitcoin perfect enough to replace the banks? Bitcoin is definitely much better than banks, but going as far as saying Bitcoin will replace the banks might be too much for now.
There are several pros and cons in banks as there are in Bitcoin. The central banks are shadier than commercial banks as they are the ones involved in printing money out of thin air, putting up unfair regulations and policies, and so on. But overall, there are so many banking services that Bitcoin cannot give for now. Taking care of your savings with interest and insurance is a service the banks give that Bitcoin cannot, at least for now. Offering micro and macro loans with or without collateral is another service the banks offer which Bitcoin cannot. Offline services with or without sophisticated technological equipment are offered by banks, too. These are just a few things that I would say the banks are somehow good at which Bitcoin lacks for now.
For variations in the completeness of the type of transaction to date, the bank is still in the lead. Especially is banking services such as letters of credit and cross-border business transactions with great value.
It's just that the bank is a sunset business because now the bank's work or services are replaced by banking 5.0, namely by non-bank online platforms such as (Skrill, Paypal, Alipay). In addition, the banking system with interest is something that causes economic inequality in society. We can learn how the internet kills the newspaper industry, how the market place kills many retail companies, if banks don't evolve, sooner or later it can't exist not only because of blockchain technology but because competitors from banking 5.0 (online payment platforms).
India is a country that is fast absorbing technology and they are very open to technological developments, so if bitcoin is adopted in India, its development will be very rapid. It's just that the demographics of the Indian population today are still dominated by older generations so it will be difficult for them to accept change. Maybe some private banks have a poor track record, but the older generation still assumes that the bank is the safest place to stray money, let alone state banks provide compensation if there is a loss caused by the bank.
