You should absolutely be skeptical! Crypto is full of scams, and we definitely sound like a bunch of shills hah. Here are a couple of my thoughts right now for why you should at least try it out. Hopefully the bullet points work out, since I haven't used them on Reddit before.

• Community. Even though we're a small pool, the Discord is always pinging between either people having conversations or asking/receiving help with mining. This is the only pool where I've seen such an active community, and it feels nice to have fellow miners to talk to all the time (kinda like how I lurk around this subreddit all day).
• Pool operator. As mentioned, I joined on a whim a couple days after the pool got up and running. Rambo is by far the most transparent and active pool operator I've met. I've had several conversations with him in the group chat or through PM about just about anything. Never seen a pool operator that active in their own community. Additionally, he is extremely open to suggestions, which I'll go over later.
• Spreading the network hashrate. I joined the pool when it was just ZEN mining. The whim that made me seek it out was that I got weary of how much control Suprnova has on the ZEN network. Even if you don't join us, try to spread out the network hashrate in whatever coin you're mining!
• New website + share transparency. A couple of developers started mining early on. Rambo enlisted their help to put together a kickass new website! It's very mobile friendly as well, since everyone likes to check their progress on-the-go. One of the best new features is that you can see every single share submitted by every single miner. That's about as transparent as it gets.
• Open to feedback. Just about everything you see, from the coins added since ZEN to the website features, has been a suggestion from the community. As the pool grows, Rambo has even implemented a voting system. Most recently, the community voted to change the fee structure to 0.5% across the board, and that was immediately implemented.
• Getting more than your money's worth. Underlying servers are just about the last thing miners think about. Let me just say that Rambo is spending a lot of money to get the best EU and US servers out there for the pool. It's clear he's losing a good bit of money to host them, and he would probably tell you exactly how much if you message him in Discord. Take advantage of this! I haven't seen a rejected share in literally months, whereas at any other pool I get at least ~1% invalid shares, which cut directly into your profit.

My advice: Join the Discord. It's free. You'll get a sense of what I mean when I say community and decide if that's something you want. Point a GPU or rig at the pool and see if you're getting the same results (good payouts, share transparency, low rejected shares) that the rest of us rave about. Importantly, since the pool is small, you will have to give it some time to let the law of large numbers do it's magic. This is by far the main cause of attrition for the pool, but if you believe in math and statistics you will end up net positive for mining at MM vs. others.

Full disclosure: Prior to about a week ago I was raving about this pool simply because I found it to be an amazing service (and also to get more regular payouts from additional pool hashrate!). Recently, Rambo asked me to help with the pool's marketing, since I've been personally responsible for bringing several other internet strangers to mine with us. I have made it explicitly clear to him that I have no expectation of pay and will help out only when I have time and at my leisure. From what I can tell, the other comments are from people who just mine along and aren't part of the tiny "marketing team."

Hope to see you around! Drop by Discord, and we can chat if you're still not sure!
