An expired domain enters a 60-day redemption period.
During this process, the former owner of the domain can re-register.
After the end of the 60-day period, the domain finally enters the 15-day pending delete process, but the previous owner of this domain cannot extend the period during this period.
After the expiry of this period, the domain is activated by other registration companies to be registered.

In summary; After 60+15 days, the domain becomes wasted.

Note: Let's not forget that if anyone has backordered the domain in the last 15 days, the highest bidder will be able to buy the domain 72 hours after the end of the 15-day period.
