First of all, if crypto is banned in your country and you still doing it then you should avoid making it public. But still, there are many cases i have observed in mine too, like when crypto was banned last year maybe it was 2021 (idk which year was that) but at the time, crypto was banned in my country and authorities caught many traders in big cities only and they blocked more than 1000 websites directly related to cryptocurrency exchanging activities. But that ban was removed in 2022's last quarter and then again crypto is declared banned the previous month and there has been much unofficial news about catching those who are involved in cryptocurrency even Binance said on its Twitter that, we are working on it. This indicates that this time our government is serious and they really want to catch someone (involved in crypto). But still, many YouTubers are making live trading videos while sitting in the country where it is banned and using the cryptocurrency publicly and even sharing signals and other ideas plus advice for traders and holders and for any crypto geek. And no one is asking them.

The point is, i do not think that sharing your exchange on which you trade crypto in a country where crypto is banned will get you caught. I think that the trader might be involved in something. i hope that's not true but still, the government needs an excuse to put someone in.
