Received briqs have a lifetime of 365 days, after this period of time they will expire if not redeemed in the Bootiq.
If you are using Briq on slack, you can easily check this information by typing /briq in slack, clicking on "Get insights" and then "Expiring briqs". This will give you the number of briqs which are about to expire in the coming month and in the 3 months to come.
Just so you know, every time you redeem briqs in the Bootiq, the oldest collected briqs will be used.
Currently, it's not possible to change this parameter, but it will be soon... stay tuned!
💡Tip: In order not to let your collected briqs expiring, you can create group orders for any item of your Bootiq. This way, the committed briqs won't expire.
