Which cryptocurrency has a very limited supply?

As a seasoned individual in the cryptocurrency and finance arena, I must ask - which particular cryptocurrency stands out due to its highly restrictive and limited supply? I'm intrigued by the concept of scarcity in digital assets and how it potentially drives value. Given the volatile nature of this market, it's crucial to identify cryptocurrencies with intrinsic rarity, and I'm curious to know which one best fits this criteria. I understand that certain coins are designed with a fixed cap, but I'm seeking clarity on which one specifically has a supply that is so constrained that it commands a significant premium in the market.
