If they are going to launch version 2 then I think they will keep all their user data instead of starting fresh and let everyone to register once again, I do think that it is not needed
In the chat they told everyone should make a new account, so that's why i ask it. If they could import the users then it will be great.
its possible that they will require a new account coz the beta version will be separated from the old MD1 but that it will prevent loss on users information but out of beta they should use the old data coz it still have the old users balances on their accounts
Im sure all players balances will be safe when they launch MD 2. Shouldnt be any issues at all
