In Europe we have really innovative Fintechs which build awesome apps like e.g. Revolut (which are also in beta in USA) or N26. But guess what: Also fintechs have to comply with regulation and need to comply with AML (Anti Money Laundering) with their software and you also can get in trouble there. When you have problems there then sh*t hits the fan too: You don't have a branch were you could go, not even a telephone number, only chat in the app and maybe twitter. It's like Google for finances.

Ideal would be a combination of both worlds I guess.
