I have zero confidence if their official pool is any indication.
I'm mining on their official pool for weeks, since Supernova is not accepting Z9 on BCI pool and I have had zero issues, works absolutely fine, I'm sometimes even getting more than projected on whattomine, but that's just luck.
Excellent! Myself, I received payment for the first about 13 coins I mined, then payments stopped. I stopped mining when my balance was around 34, stopped and made several attempts to contact them through their official thread here (I can't use Telegram, and that is the only contact option they provide). Had several separate conversations with them in that thread that all said either "use Telegram" or asked for info, which I provided, and then nothing. Crickets. PMed the guy I was talking with, even emailed him at the email in his profile, nothing. It's now been three weeks and that balance is still in their pool, so I decided to just give up on that coin. I hope you do well with it, sincerely, and I even wish them well, I don't want anyone to be scammed or lose out, and I still don't think they're a scam pool or it's a scam coin, but that level of lack of effort to work with people who have problems using their pool is just astounding to me, so I have no interest in that pool or their coin.
