Correct. It has been already illegal* to use cryptos as currency in China and India, aka 1/3rd of the world. https://techcrunch.com/2018/02/03/p...itcoin-but-its-still-talking-tough-on-crypto/ "The point about the Indian government not recognizing crypto as legal tender was already made by Jaitley, back in December." *Now maybe it isn't the law yet, but looks like it will be soon: "Jaitley: We are discouraging people from using it now. There is a government committee that’s looking into it right now and they will announce their decisions and next steps after they are done."
There are bitcoin ATMs. Also if you withdraw from your crypto broker in USD (if they let you), that is perfectly legal. You can also cash out locally when you advertise on Craigslist, although that can be dangerous.
