Ok, I got a solution from https://github.com/ethereum/go-ethereum/issues/18383#issuecomment-451125546

It is too dangerous at any cost. If the server goes down due to some malfunction, will that make all the coins disappear?

Other crypto like bitcoin or substrate never be the same.

Not really clear what you're doing and on what network. Blocks mined should not disappear, unless you're running a single-node network and you crash geth. In that case the data kept in memory is lost and there's nobody to seed it back to you. But that itself should not happen either if you shut Geth down.

If you want to mine on any existing network, you should make sure you are synced before attempting to start the miner, otherwise it gets weird. Also 1000000 is not a valid mining reward on any ethereum network, so unsure what code you're running that produced it.
