Bank is after me because of Bitcoin

Hey guys

My bank is after me, I’ve invested in Btc and they want to know my balance on exchange and wallet, exact amounts and proof of holdings. What’s next they are gonna ask for my seeds??? They will shut my accounts down today. Because I’m scared of providing them proof, what if they get hacked one day?? All my info, holdings, personal number, phone number, address will show up.. they are gonna close both business and private accounts, setting me in a terrible position. I’ve called another bank and they told me that they only want to know my holdings. But I don’t feel like giving it to them, but they don’t understand what risk involved with those informations.
