Extend an existing crypto change-feed subscription from /crypto/feed by 30 days, using the same feed_handle. Renewing before the expiry date adds the days on top of the remaining time, so polling never has a gap; renew late and the month starts today. Your cursor lives on your side and is unaffected.
