John Langut is correct. It's just a matter of time before being anonymous is eliminated by regulation. Yes, people will look for ways around it, but just like Napster and Torrent they'll starting tracking you.

Any exchange in the US that exchange Fiat dollars for cryptos are already regulated as security dealers and require identification.

The idea that some how buying and selling will be totally anonymous is a dream. Governments aren't going to let that happen
