With Hong Kong's cryptocurrency regulations fans are real bothered about whether or not they can wear the Chelsea jersey without breaking laws in the process seeing as wearing the jersey can be seen as promoting the USDC stablecoin and it's not just about the people who will wear it, even retailers are concerned and the concern is very simple 'can selling or wearing the Chelsea jersey with the USDC logo be seen as advertising or promoting a stablecoins that isn't licensed in Hong Kong'
https://news.bitcoin.com/regulation-and-legal/chelseas-usdc-jersey-deal-triggers-fears-for-hong-kong-fans/If there's a ban or prohibition on cryptocurrency-related services or transactions in Hong Kong, I doubt if someone will be going against the law on that since you are not selling or offering any services of such, so the real intention should be understood, and besides, you're only supporting a football club and not a crypto company, and what's written on the jersey of the club you're supporting should not be of much concern, so I think this case is clear, and secondly, it won't be too noticeable for the law enforcement agencies in Hong, Kong. However, if that would be a problem, then I think their government should come out clear whether it's legal or illegal to do such; it is now left in the hands of the government of Hong Kong to decide.
