My bank kicked me out simply for having bitcoins. They demanded information about whatever transactions I make. Obviously I told them to fuck off, and that was that.
Had I gone along with it, they would eventually have pushed for more. Access to monitor my wallets, maybe eventually direct access to them or demanding that they hold them in custody. Be careful.
my bank has no issues with coinbase. yes i use coinbase, since 2013. never had any issues at all. the amounts ive moved have surely caught the banks attention as any individual transfers over 10,000 USD get flagged. and i dont try to hide them (called layering? i forget. theres a term when avoiding hitting the 10k limit, like 9700, 8500 etc). so i do 10k on the dot chunks.
