Earned vs Spendable — the two wallets

• Earned holds task pay, ad views, offerwall rewards, streak/ladder bonuses and referral rewards. It is the only wallet you can withdraw from.
• Spendable holds deposits and refunds from your own jobs and ads. It can only fund jobs and ads.

You can move money from Earned into Spendable (to fund your own jobs without depositing) but never the other way round. Every movement is listed in Wallet → Transactions.
