Why deposit addresses expire after 24 hours? All gambling websites and exchanges I know allow users to use deposit addresses forever. It's not a big problem. Just curious to know the reason.
Not all IMO, there are still some sites that changes the deposit address after there is one transaction on the address. One of the site is sportsbet unless they have changed the system lately, but indeed most other sites lets users to use one deposit address only so it will be easier for them to make deposit as they do not need to check the deposit address anytime they want to make deposit.
