No supply cap. If this worries you dont use it as savings. Save in Bitcoin.
Stable predictable supply with inflation less than that of gold and continuously falling %. Bitcoin will be more scarce by ~2040. But right now Monero has less total supply than Bitcoin.
Use Monero for what it is better at a MoE. As p2p digital cash in your pocket. Much cheaper tx fees <1 cent that get cheaper the more txs there are. No tedious, slow, expensive, and inferior CJing necessary. And comes with strong default privacy.
