If you created a wallet before January 2018 and have recently created a new account, you can now create a new wallet. The new Bitwala wallets provide an improved backup process and are a requirement to buy and sell bitcoin within your new account.
If you have an old Bitwala wallet with a positive Bitcoin balance, you can transfer it your new account.
To do this:
1. Create a wallet in your new account
2. Transfer your bitcoin from your old wallet to your new wallet.
You can access your old account here.
