Completion of a withdrawal transaction from a Bet365 betting account can vary depending on which banking method is used. So, Paypal, wire transfer, Mastercard, and direct bank account withdrawals will vary in their completion timescales. Getting cash out can take varying amounts of time in different countries, too. If you activate the request from Australia, New Zealand, or Canada, it may take more or less time than in India or the United Kingdom.
A cashout request could also be delayed if you had not completed the account verification processes successfully. That's a good reason to verify your account before you get to the point of requesting a payout.
To list all the variations of timescales here would be impossible. Fortunately, there is a bet365 table of withdrawal timescales in the site help section. Here. you can enter your country and currency and see all the available options.
