People dont read. I had to format my pc after I used his wallet. Scary. Hope people wakes up and stay away. Or he will take your money like he did with 2 guys on discord.

One thing I don’t understand is, why are miners still mining this coin?

So you were talking about fake devfee rate 1.3%, now it's fine but there is fake hashrate 1.5%, right? Where do you take these numbers? Ok, probably you have own good source of them.
From my experience, I always see a couple of percents fluctuations in hashrate on pool side, and usually it's a bit less than miner shows because miner shows raw hashrate, i.e. it ignores devfee, stale and invalid shares, startup time, dag creation file and other minor things. But pool has to calculate miner's speed from shares only so there is some small error rate there, always. And hashrate that you see on the pool is "final" hashrate, it's always a bit lower.
Anyway, if you don't like hashrate that you see, or don't believe it - just use some other miner that shows better numbers or numbers that you believe. I even saw reports like "I tried miner X and now I see +10% shares on pool", so some people think that they get a lot more than 1.5% after changing miner You can try this way too and find the best miner for you, no one forces you to use my miner if you don't like it.
PS. I assume that you don't use "devfee cut" tools or cracks, in this case miner really may show some fake hashrate, read Readme for details.
