Bitcoin Miner (Mobile Game) Review




URL:  Official page (only available as an app download for Android, iOS or Chromebook). Once in-game enter friend code AYBLC8 to get 30 free nodes. 


An ad-supported mining game with the twist of earning fragments of Bitcoin (SATs) as you play, time investment increases your daily payout amounts as you build out your mines.


NATURE OF WORK AND PAYMENT


Bitcoin Miner is part of a growing family of "SAT earner" games under the banner of developer Fumb Games, which all follow the basic formula of showing ads sporadically as you play and then kicking you down some of the earnings in the form of SATs. I think Bitcoin Miner was the first of the bunch, first released in 2018. 

The "work" so to speak is just playing the game normally, picking up SATs here and there as you go, and watching a forced ad occasionally in the usual mobile game style. The SATs you earn have to be transferred to the ZBD wallet/earning app, a different thing you'll have to download and set up (and if you're on Chromebook it's not available as of this writing, you'll have to set ZBD up on an Android device first, but once you have a wallet address you can play and transfer SATs out from your Chromebook version of Bitcoin Miner. Tested and confirmed working just fine by me personally). 

In addition to having to cash out to ZBD, there are also daily limits on how many SATs you can withdraw. It starts at 300 per 24 hours in the US, and quickly moves up to 330. It's been sitting there for me for a couple weeks now, but word online is that it can increase to 400 or even 500 at some point; not clear on what triggers that other than just a certain amount of time or withdrawals passing, which I see no in-game information about.


SITE HISTORY / LEGITIMACY


Fumb Games is a legit mobile developer based in the UK that got its start in 2015 and is backed by venture capital. They're obviously tied in with the ZBDverse since that's the only way to withdraw your earned SATs, but as third-party partners rather than part of the main operation. ZBD promotes their games pretty heavily within its own app, but they are two separate operations. 


INTERNATIONAL ACCESS


I found a helpful Google Doc that not only lists whether or not the game is available in a given country, but also its daily withdrawal limits. Generally speaking, big developed countries can be expected to have the game available on app stores and a daily withdrawal limit of 300-500 SATs. If you're in a smaller or "developing" country, it might be available but with only a 1-100 SAT daily limit. Some countries appear to be entirely blacklisted.

The chart indicates you might be able to sideload the game in countries where it is not officially available, but generally the withdrawal limit is set to just 1 SAT for these places.





STARTING OUT


Bitcoin Miner is a fairly standard "idle miner" or "idle tycoon" game. You start out with one mine, it auto-delivers profits to you gradually on a conveyor belt. Eventually you get enough money to open another mine, and another, and another, increasing your total earnings. For this game, each mine produces a type of real-world crypto token (though you don't actually get the tokens in question in real life). 

Of course, all that would be terminally boring if that was all there is to it. There are some elements to spice things up a little and build up faster. You can divert some of your mined money to upgrades such as earning boosts for each coin type you've unlocked and speedier conveyor belts. Often a power-up comes down the belt attached to each coin, which you have to manually click on to activate (either increasing its value or redeeming it immediately, sometimes you also see a rogue bonus SAT here to grab). You can opt to watch an optional ad (or two) to get a temporary speed or 2x earnings boost. And on the "optional videos" front, sometimes a power-up comes down the pike with your coins that provides bonus money, a treasure chest or some "nodes." Nodes are a different pay-to-win type currency that allows for purchasing permanent income upgrades among other things, the treasure chests contain coin upgrade pieces that permanently boost your earnings from each token type. 

There are also a couple of bonus games that cycle in and out roughly once a week. The one to look out for is the "rescue the Piggy" game, which usually furnishes you with some bonus SATs and a whole bunch of nodes if you play  it for a bit. There's also a "build a rocket" game that's pretty much like a mini version of the main game, and not quite as rewarding. 


PROBLEMS WITH BITCOIN MINER


Bitcoin Miner is a pretty well-made game overall, doesn't have significant crashing or glitching problems, doesn't serve any weird or hostile ads that I've seen, pays as agreed. The forced ads can be fairly frequent, it seems to vary with different play sessions, but the ones that pop up as part of the regular game are generally only five seconds long and easy to get out of. The longer ones are reserved for when you go for an optional power-up of some sort. 

The one technical issue I've seen at times is some odd syncing problems. This took place on Chromebook for me, which seems to be more prone to game-glitching than Android. But occasionally I find certain isolated aspects of the game are "forgotten" the next time I go to play; whether that be the countdown for the daily drops, for opening the next treasure chest, or something I earned or bought during the previous session. It seems to be happening less often in recent weeks, so it may have been addressed by more recent updates.





FINAL VERDICT - MIGHT WORK FOR YOU


Bitcoin Miner is fairly visually appealing, has a cute little sense of humor with its "generic brand" parodies of game and crypto figures, and is easy and smooth to play. I mean it barely qualifies as a "game," but it does allow you to make at least some basic strategic decisions while also allowing for progress while totally idle. It's also a fairly small app and doesn't waste a lot of your storage space with endless updates.

The only big problem is low earnings potential. While you can easily make more than this in a day, you're locked to withdrawing only about 50 cents USD worth of SATs maximum (and maybe a lot less depending on where you live) per 24 hours. That's a hard cap of about $15 per month, and while it can be done on what averages out to just a few minutes of time daily once you're built up and going, that's still pretty thin. It's worth doing it through a GPT site to hit those goals and get around $20-30 out of it, but after that's over it's questionable whether to keep bothering; probably only worthwhile if you use SATs for gambling or really believe in stacking Bitcoin for the future. Would easily be moved to the "must have" category if the withdrawal scheme was better, however.
