Nitro Up

I buy Nitro or some kind of exclusive Nitro subscription, which does not apply to any discounts+separately for the full price (without discounts) I buy 28 boosts and as a result I pay only for the Nitro subscription and all the purchased boosts do not burn out.
Cancel the 3-day grace period.
If the Nitro subscription was not renewed in time, it is disabled and the purchased boosts are completely burned and you need to buy them again for the full price. If the subscription was renewed on time, the boots remain active.

It may be economically unprofitable for the company, but it would encourage users to make such large purchases.

Or give a similar opportunity to the owners of the servers (with the restriction that the purchased boosts can only be given to your server).
As the owner of a large server, I would immediately take advantage of this opportunity.
