Kaspa isn't the only cryptocurrency that has levels of similarities with Bitcoin.
You just mentioned supply, halving, etc which can be said about any coin.
I absolutely disagree.
Litecoin, bch etc have it all. But they are not instant.
Bnb, xrp, sol, neo are instant. Or nearly instant. But they arenot PoW.
Kaspa is the first and only coin with such properties. Bitcoin 2.0. Everything bitcoin has + real-time.
