Still, I think that soon or later banks will try to stop bitcoin because they will start loosing clients because of us.
you are wrong
thats like saying banks will stop accepting wire transfers from apple stores because apple are making products, to banks, bitcoin is a product. and people will want to swap fiat for products and products for fiat.
where ever there is a person selling a product there is a person buying a product. so when you buy bitcoin. you are handing fiat to someone else.. your not making fiat disapear, your just moving it into someone elses hand.
banks love that, they actually enjoy seeing coinbase holding millions of dollars, they love coinbase swapping with other people. once you see that bitcoin is a product you will see that it helps bankers actually have something to do.
what banks do not like is having to fill out paperwork to explain to regulators why they let through $10,000 without question. so although they love moving money, if they see that +$10,000 is being moved they know they have to do alot of paperwork, checks, double checks, writting letters to customer to explain things, yada yada yada..
so its easier to just freeze an account to give them time to do the checks and question the customer. rather then just letting it through and giving themselves not only a instant headache, but also backlash from regulators.
so if you are going to move +$10,000.. WARN YOUR BANK, explain where the funds are coming from, their purpose, so that they can then not have a surprising headache, and instead get the ball rolling to let yor funds through without headache or large delay
