For me, Bitcoin = no banking needed. At least in a form of keeping our money safe. Banks became big companies that want you to lend money from them.

If bitcoin replaced the money completely, I think it's impossible, we know we use bitcoin, we must have internet access and other devices can support and bitcoin price is not stable, we also know Every bitcoin has no physical form, I think bitcoin is better suited for long term investment. We will be on the moon.

Basically, you are asking if bitcoin can become a globally accepted currency?
It highly unlikely. It lacks misfits of the qualities banks and financial organizations look for in a currency.
The blockchain technology however could be integrated into the banking system.

home to store personal money. this analogy can be made. it could be your future bank.
 but I think the banks are located in the center of the world. it is not so easy to shake it. because we need a bank. we need the power to manipulate their infrastructures.

It is possible, but certain things need to be put in place, especially in undeveloped nations with less internet access

Maybe. But as of now i think it's far from being possible. Yes cryptos at the moment are really famous but it's not yet implemented by the government. And since it has its own decentralized system, I think the government would find it hard to trace all its users. Maybe after long, long years the government will acknowledge cryptos if they are still existing by that time. Beside this I've read some article and it says there that it is impossible to replace the fiat of other digital cryptocurrency. It shows there also of how money dollars reserve they have and digital currency has just only few reserve so its impossible to replace it. Aside from that digital cryto is depending also on fiat. Without fiat, digital currencies are nothing.

Maybe we will end the bank with bitcoin! The blockchain can perform all the functions of the bank.
Banks must change the status quo in order to comply with the development of the times, in order to better serve humanity!

sure, bitcoin may be used against the financial institution in the destiny. usually, if we hold the money inside the financial institution, it takes a every year fee and there are numerous responsibilities to perform. if we shop it with the aid of bitcoin, it'll work like a type of investment, and we can switch it to our desires. in any other case bitcoin protection is excellent and safe.

I think that btc is the future of banking and other spheres of life. to my mind, the best way is to trade regularly and hold some expensive coin like btc for the long term until the price becomes better
