Why do you panic like this. you are not dealing using central currencies, if the third largest currency is affected by banning it in a country, it is better to think carefully about that currency.
The price will be affected, but you can still sell. If I am in your place, I will try to buy more because it means the best opportunity to make some quick profits.
you can use any Dex wallet or exchange. try coinomi and this topic https://bitcointalk.org/index.php?topic=2906237.0
