You can change the nLockTime to any value you want. Reduce the time and you will be able to get the private keys sooner.
and how about mycelium , i used that for preparing 1 Aug
did i must backup wallet or what ?
actually i not really understand about this trouble.
but as i read on steemit or everything news, u must keep ur bitcoin safe on ur wallet.
As far as I know, with Mycelium you are the only owner of your private keys.
However I'm not sure if you will need to export the private keys to have access to the Bitcoin Cash in that chain or they will implement a way to send it from your addresses.
If you need to export your private keys, select the account and choose «Export» from the pop-up menu.
