I don't know about him, but sometimes in some countries the governments have not yet decided what kind of approach to take about cryptocurrencies and some people prefer to keep their privacy in case their government suddenly decided to take an aggressive approach in which case those with a lot of cryptocurrency related transactions can face a hard time and a lot of legal fees to solve something that could have been avoided.
It happened with some countries earlier like Bangladesh I guess where holding any crypto currencies will be a punishable act but now knowing the current situation there,they might change their activity later as well even after they said they are going to ban it.
But when we want to avoid these cases then we might have to find a buyer locally and the prices also will be lesser from the current price,if people are ready to do this to keep their privacy then no problem for them.
