Having studied the features of Karlsen (KLS), I believe that this coin does not have a serious future. Even if KLS is listed on some exchanges, it’s unlikely that this coin will take off. There is a lot of competition in the cryptocurrency market, promotion requires a lot of money, which the developers do not have, judging by their website and information about the project available on the Internet.
Idk man, pools are picking it up, hashrate is making a killing, first kaspa clone steering away from asics. Sure, speculative at this point, but even kaspa isn't user/time tried and tested like BTC. It definitely fills a niche. Going to be fun to see a first listing.
