I've been following the trend news of central banks creating their own digital currencies but a question have since then troubling my mind.

1. These new Central Bank coins are they going to be stable coins or not?
2. What will happen if they are not stable coins? If holding them will be profitable many will leave crypto space and focus on these new coins?
3. Maybe people will just use them as a plus since it's from the government?
4. Will regulations still come after this? I think other coins will be neglected and regulations will only be for coins from government?
