When they unbanked me, they didn't ask about bitcoin. They only wanted to know why I had more than 100 incoming transactions with amounts all over the place. I was market maker at localbitcoins at the time and that's what I told them. Four days later my cards stopped working and when I went to the bank, they told me I had no account with them. Only after asking higher ups did they find that there was a check I could deposit to any other bank account with my remaining funds.
