I guess we are gonna have to create a new account after the new genesis has released, right? the accounts from the testnet wont hold, right?
accounts and everything hold, even your enode address, the only thing that changes is the chain. If you want to be super cautious you can run this cmd on linux.
rm -rf ~/.expanse/{chaindata,dapp,history}
And what happens to the "test" coins that are already in those accounts?
They are not in the account per se...
They are in the network and are "unlockable" (being able to be sent) with your account's private key.
The new network will have different instance of your account's address and will be "unlockable" with the same account's private key.
Ergo - the account is the same (address and key), but the coins are different because it's a different network.
Analogy (loose):
The account's address is like a template - a plate with holes that lets you see certain amount of information.
If you put the template over a book page you will see some characters through the holes. If you point it at different page
characters will be different, but the template hasn't changed.
