Balance hook on the Card component

[crisog]

This component has a 'balance' useState hook which is passed through the Context to the Step3View, but sometimes the value of 'balance' is empty when you click 'Create DAO' button which is also on the Step3View.

Expected behavior: Click 'Create DAO' and check that value of the 'balance' hook is greater than 0.

Current behavior: the same thing as above, but sometimes comparison fails because the 'balance' value is empty.
