I unregistered my Stake Pool (SA4M) at the end of the epoch 305, now we are at epoch 306, I was able to move the related wallet content (unregistered it) but no clue about those 500 ADA I put for Pool initiation.
I re-registered the wallet address but nothing more.
Here is the command+output of the StakeAddress (the one given by cntools):
cardano@cardano-blockp-1:/opt/cardano/cnode/scripts$ cardano-cli query stake-address-info --mainnet --address stake1u9x98hyvudylz9emgc4vaj4g75vxrq54lpt4ctu75fvj88cssrnqz
Thanks for your help
