Just some observations about the current play-ability of this game.
To log in I get 4 pop up windows which are potentially (the more people that get frustrated with process and block pop ups the more this format actually hurts the site) nice for monetization but do nothing to help me play, as I an still needing to login. I click the mine button and then am told to prove I''m not a bot. Not by doing the increasingly common 3 option captcha that gives option for input preference and redundancy, but by going to a series of short links.
The bot check is not about bots at all, but a check for the submissiveness of game's user base. Maybe that is why a good percentage of the short links show sexual fetish, include malware (instances of google pay being opened from a short link, "virus" warnings, downloads started are just some examples), and are either broken or send the player to another site instead of back to cmg. From 2 quick pages to literally more than 20 pages I have shown I'm not a bot and given a fraction of satoshi. Throughout the remaining clicks for mining, missions, and other site fun I get frequent popups.
Each popup and questionable content pushes me to search for browser add-ons and other options for my game time.
Level 12 mining takes 2 hours and pays about 25 satoshi at 350 HP. Missions pay 32% of the indicated HP and more satoshi then the mining (multiple missions during equivalent mining period). At higher HP levels (well over 1000) mining would provide more than missions.
The current Alexa public information shows site ranking declining over the past weeks and currently 22,229. Compare this to a site with minimal ads, a mining game that doesn't take 1mil satoshi to mine 100 satoshi/hr (cryptomininggame gives 100 sat/hr for 1700 HP mine, 1700 HP costs about 1mil) - a popular site has a mining game that is paying over 500 sat/hr with no downtime for the same 1mil, not saying the name here but just the Alexa rank is 25,991 and climbing over the past weeks. If the site keeps on the same trajectory then the already pedestrian return for most players here will just get lower.
If I paid the 1 mil with whatever additional fee there is and ran the mine 20 hours a day, it would take 500 days to recover the investment. I would have been paid additional satoshi for missions and bonus, but that is not related to HP at all. Maybe the 1 mil would stay in force for 500 days, maybe part of the purchase is a 1 year contract, or maybe something else. Then there is the percentage based withdrawal fee (does it really take twice the work to send a 100k payment compared to a 50k payment?).
The site owner and a few others with 10k HP have to keep on clicking to break even from the payments, but regular users have other less abusive options.
Happy mining
edit - I estimated the cost for HP and the duration to recover investment, if you are considering making a deposit do your own calculations. The HP won in missions is about 32% from my experience, but that won't matter to those with over 1k HP. Hope admin enjoys vacation and comes back with new ideas on how to clean up the site and make it more enjoyable
