How to see your CFG balance after migration to parachain

Glad to hear you figured it out.

No, there is no more staking as there are no longer validators to secure the network - there will be collators instead. The security is provided by the Polkadot Relay Chain validators to all parachains. Hence, there are no reasons to stake CFG tokens to secure the network.

However, there are other ideas for utilities of the CFG token that the community currently is discussing. You can find the ongoing discussion here. Feel free to join with input if you have any good ideas.
