Judging by what this script does, it would take me few hours to replicate and fake the behavior of miners in a node.js and make an army of 'web clients' that sends in hash rates and just mines it.
Imagine what a real hacker could do here.
The more-than-likely case is that, as with the typical pool, it sends "work" to the script to be completed (aka. "mined") and then reports the results to the pool. In turn, the pool has a record of all work done by the specific miner's ID (which would be akin to an 'affiliate ID' in this scenario.)
If it was like you suggested, that you can just spam 'submitHashRate' requests with some numbers, without doing the actual crypto\compute work, then they would be over on day 1, crash and burn, complete failure and retardation. Unlikely to be the case.
As I understand, now all that dropin javascript is doing is mining this coin and no real value is produced. So it's printing itself?
From what I gathered, the company's intention is to "outsource" cloud computing capabilities onto the miners of its network, thus having a distributed army of end-user machines ready to be sent cloud compute work, which they will sell to Enterprise clients. There may be some other mining going on as well, of either their coin or some other coins, if no cloud compute work is available at the time (I have no idea if this is accurate, but it seems so from what I've read.)
They would then pay their affiliates\webmasters in their GTH coin as payment for providing an army of regular web users that can perform compute tasks for them.
They seem to be founded "Mar 15, 2018", so they've been around 3 years now, and run on the Ethereum smartchain.
Also note, I don't believe you can mine this coin yourself -- at least I don't see anything anywhere written about being able to. You can run a node for them and get rewarded, or I guess you can join them and pay this 'joining fee', to then be allowed to do this compute work for them and get paid as an affiliate.
If you ask me, the $75 joining fee is ridiculous -- and as many have suggested, that $30k in coin delivered as payment to the OP... it definitely seems suspect, and at this point makes no financial sense.
We need a clear answer HOW\WHY those 60k users x 20% acceptance @ 5 minutes of 'active work time' is supposed to be worth $30k (much more, since that is just the affiliate's cut.) If someone can show how this is feasible to pay out, then we have a more enlightening answer to ponder upon.
Boy would I love for this to be legitimate... but like some other poster mentioned: Who is going to share a $30k/week legitimate method, rather than stay quiet and milk it to the very death until they no longer can?
