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 are not PoW.
Kaspa is the first and only coin with such properties. Bitcoin 2.0. Everything bitcoin has + real-time.
About smart contracts - yes. They have plans to add them. But currently kas can't do it.
In the present days, we have been seeing crypto projects that are having similarities with Bitcoin so that they can be a topic of discussion.
I think this project would be a greater one in the future. I like projects like this because they could do better in the market in the nearest future. If the team knows what they are doing and know how to do the marketing that would make more investors to know about their project, in a short time, there market cap could go as far as competing with other crypto projects.
