bitcoin can impact banks profit if it is allowed to thrive, but banks can also benefit from the blockchain if properly used

I don't think so. Bitcoin is great asset for countries with economic crisis, but developed and developing countries won't use it as main payment method! While BTC is slow and has high fees for transactions, it can reach global market.

as far as there is no main reason why banks do anti-bitcoin. although some crypto lovers say banks are not able to compete fairly with bitcoin.

yes, you are right, when all the people of the country start using bitcoin or altcoin in transactions, the bank will lose its role, the reason is clear because bitcoin does not need the role of the bank.

For me yes, because bitcoin can also do what banks can, you can invest in bitcoin, you can save money in it and also you can earn in bitcoin. In banks before you can invest in it you need to pass some papers and you need to attend some appointments and also you need to have a lot of money and lastly bitcoin can multiple the money you earn in banks.

I think bitcoin dont give big effect to local banks. Bitcoin used for transaction thru internet. Maybe give a effect but i dont think it give big impact because local banks mostly just for loan and saving

Bitcoin is not a disaster for banks, because Bitcoin is used with a different function than a bank. Banks use to finance, lend, do some national work, it is easier to use than Bitcoin. Bitcoin will need a lot of new elements to replace the bank.

Still it is not true as far i know because in most of the countries it is still ban so, bitcoin is unable to fall ant impact to the local banks but may be in future it may prove to be so.

I do not think so. The function of banks and bitcoins are not the same either. But, what's the same is the circulation of money. You invest in banks as well as in Bitcoin, you earn money in banks as well as in bitcoin but it doesn't guarantee that bitcoin causes disaster to banks. I think, when you are going to look at it in a different angle, much people now invests in bitcoin than in banks. Apart from the fact that it is decentralized in bitcoins, more people nowadays prefer to handle their own money. In the contrary, people who wants to have their own business actually goes through bank to bank when you talk about the financial legalities. Therefore, it really depends on the people.
