The maximum amount of money you can withdraw from Betika on Airtel line is Ksh 10,000 per day. This means that if you win more than Ksh10,000, you’ll withdraw Ksh10,000 and wait to withdraw the rest the following day.
Assuming that you win Ksh1 million, you’ll have to physically present yourself to Betika offices, fill a form where you indicate your bank account details. The money will be transferred to your account.
If you want to withdraw more than Ksh10,000 per day, it’s good to buy a Safaricom line. You will be allowed to withdraw up to Ksh70,000 per day.
