You know, one of my plans was to buy numerous Bitcoin and Ethereum polo shirt and wear them (to help promote). However, as it stands right now, I'm afraid I can't do that because I could be held as a user of cryptocurrency.
There's very little chance that your bank will go as far as checking what kind of clothes you are wearing to determine whether you're a cryptocurrency user or not. Usually they just notice that you send or withdraw fiat money from exchanges to their bank, and then decide to freeze your accounts, because they don't want to risk serving customer whose money they can't track. Just don't connect your account with anything crypto-related and you will be fine.
