First time hearing about Kaspa Coin So just imagine that, like me, many others still don't know about that coin. Then how would it be Bitcoin 2? I am pretty sure you are Shilling their project. There are a lot of similar coins, even hard forks of Bitcoin. But sadly, they didn't become Bitcoin 2 or something similar. Each coin would have individual features; it's not necessary that they compete with or replace the bitcoin. All blockchains won't be secure like Bitcoin, which is truly decentralised. So it is better not to compare any other coins with Bitcoin at all.
