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 know a lot about banks and know what goes on in and out a bank, and to tell you the truth, its not good. One thing that annoys me a lot, is that they always ask for proof of funds. I mean bruh, come on. Another issue, is that they blindside people to getting a credit card and later on charging ridiculous amounts of interest and other fees. And most of the bank, have horrible e-Banking facilities, and if you have any issues, you legit have to visit the bank every now and then. Banks suck and we are forced to live along with it. They block your funds, no matter how legit they are, for no god damn reason. They will just block your funds out of the blue and claim it to be a security feature. Bitcoin is here to eliminate the usage of 3rd party intermediaries, and its not working well, for very few people believe in it.
