Firsty, them deciding what is suspicious and not suspicious
Not everybody is an employee working for someone. Some people are entrepreneurs, and as an entrepreneur, you can have some HUGE days. I don't need a bank telling me that my successful day where i made $20k+ is suspicious if I want to withdraw all of it. (people have been arrested for making large withdraws before).
Also, banks freely allowing their customers to scam business (via chargeback). Instead of blindly chargingback purchases and screwing over merchants, visa applicants should be required to take a course outlining the risks of credit cards, and Visa should do proper investigations when a chargeback is brought up.
If a tracking number and proof of delivery can be proved, why should the customer be given their money back?
ALSO, i recently looked into banking investment options. It comes across as a way to just make more money off customers. Think of it like this. It's like it's just them taking your money so they can invest it in polyniex. I only tried it out cause my family (who doesn't know about bitcoins) encouraged it.
Do you have any gripes about banks
I have never had any problem with my bank ever since I stared making use of it, they dont charge extra fees or whatever, they just do the right thing and I also play my own part as being a good person.
I like bitcoin too, both banks and cryptocurrency favors me a lot , so I dont really have any problem with any of them. I do know that not all of us are lucky, and some people are having problem with their banks but I dont pray to be one of them.
