I heard similar stories in my country when banks closed someone's accounts when they found crypto related transactions. And they don't even have clear rules which doesn't allow to deal with crypto.
But I think you shouldn't be worried to wear clothes with Bitcoin logo. Wearing such clothes doesn't necessarily make you crypto user. Same like wearing t-shirt with marijuana logo doesn't means that you smoke weed or t-shirt with Jack Daniels logo doesn't means that you drink. So, I think you should wear these clothes to promote crypto, unless it's ilkegal in your country.
Banks are not going to look favorably on Bitcoin just because its a competitor against their whole system. Bitcoin allows you to become your own bank which directly drives business away from the bankers. They don't need to write a ruling to shut down your bank account for trading in cryptocurrencies because they have a rule that they can shut down your bank account at any time they wish.
If it was easy to get paid in Bitcoin via my job then I would have already made the transition and said goodbye to the broken banking system.
