I’m pretty sure banks can facilitate special ‘deals’ for high-volume customers in their platforms, but even those require money to get done. Bitcoin eliminates the need for paying such high fees to the third-party and just process the transaction regardless of the amount and who sent what. One of the most beautiful merit of bitcoin that has always been overlooked by many thinking that any other money transfer services can do the same.
Bitcoin eliminates entire banks, to be more specific on that, and all other third party services. Why to pay for something you can do by yourself, from any place as long as you have internet connection and device of course? It's old one, be your own bank! And with crypto in general you can a lot more than just a bank, specter of possibilities with blockchain is endless.
Bitcoin is unique for more reasons, not just that you can transfer money (small or big amounts) with the same fee, and you can adjust your fees, depends on do you wish faster or slower transaction. Bitcoin is unique because it can be counterfeited, you can't mess with explorer and change blocks as you want! And this is a simplified version, I think we can add a lot more about bitcoin and it's uniqueness.
And in the end it's nice when you can handle your things by yourself, with bitcoin you can do that!
