I guess it depends what you mean by “banks”. Different banks serve different functions of course, from holding assets, to lending money, to creating money.
Can litecoin alone recreate the whole financial world and redefine what “banking” is? I think that is a bit ambitious.
I do believe it is a project that has merit and potential to change the world for the better (along with the crypto movement as a whole). Keep holding and feeding the community as much as possible and don’t forget to spread the word. The whole movement provides so much hope for the future I believe, the disparity of wealth and power will be greatly affected by communities like this
