Kaspa is what I am seeing that's commonly suggested by other altcoin miners. The other one that I am seeing is ravencoin which has the algorithm of KAWPOW.
That's the two that are I am seeing and being mined by many miners these days. About the profitability, I don't know but if they're mining it and they think that it has got a bright future.
Prolly, on the next bull run they're all just covering all the mining expense and stacking the coins they mine for now.
There are already a lot of Kaspa coins in circulation and its mining requires expensive ASICs, the payback of which may seem dubious. I would choose ASICs for Bitcoin.
KAWPOW is probably the latest algorithm for video cards without ASICs, but this algorithm is the hottest for video cards.
Nothing beats ASICs for Bitcoin.
The best alternative PoW is $KAS is the only one "new" that has the potential to grow and survive. Check the subreddit so you can be more informed and actualized. Also, check In dextools for liquidity when you want to sell check Bitget that is one of the most used by the KAS miners and holders
That's what they are saying but not until we see the actual thing in the coming bull run then that's not yet proven. Anyway, it's one that I have been seeing popping on my wall.
Might because Google has been hearing what I have read before but they don't appear much to me anymore.
