at the very least it could be used for phishing phone calls where someone pretends to be your bank and try to get information from you so they can empty your accounts.
A good note on security is, if it's personally Identifiable seriously consider your options before posting. In your situation it would be best to black out your account number and your confirmation number.
Very cool on your payout though and i hope you have even more success in the future!
As I mentioned in my reply to the last guy, those are not my banking details - as I said in the post I sold steem for bitcoin it never even became cash and the money never even touched my account thanks to @roomofsatoshi's service.
I have been on here for 11 months and involved in crypto for many many years now, I know not to put my own bank details on the internet - but I do thank you for the concern and kind words.
