How about the CBDC? Aren't they digital currency? And yet they are under the control of financial institutions and the government unlike what you stated that government can't interfere with it. And digital currency being unable to be robbed, there are lots of hacking incidents specifically in altcoin that were announced on news paper. Being digital doe not guarantee that it cannot be robbed. Just one wrong move in security, it can be hacked or robbed by people with ill intentions.
You could just be specific and say Bitcoin is a powerful currency that the government is unable to control and is unable to hack after the incident on its early years due to security getting stronger by day.
