If I want to travel to another country and want to have foreign currency beforehand, where can I sell my BTC? I'm talking about selling BTC to a foreign currency before leaving my home country. Is this possible? And of course, is it legal? Just curious to know.
It all depends in what countries exactly you are traveling , but don't asks us to be your lawyers and tell you what is legal and what is not.
In Europe most countries are using Euro currency (with some exceptions) and good non-kyc option is to use Peach Bitcoion app with your smartphone.
There are some daily limitations with Peach, but you can do p2p exchange for cash and it's very simple to use it.
