I need to do a hot change of feemarket...

[swag-eag]

Summary

My question is: Suppose that the price of my blockchain token has changes so much that I need to modifty the minimum fee to adapt it the the new prices. How can I create a new genesis.json to only modify the "feemarket" -> "params"? Or how do I update the feemarket without missing the blockchain stored?

Do you have any link tyo documentation about this... and about changes of genesis configuration after genesis...

Thanks
