Verdict up front: Kriptoon sits at 1.8 stars. Eleven days ago a user wrote that he had submitted five withdrawal requests and received nothing. Another paid $10 for a premium plan that was never activated. A third has been waiting nine days for a fix to a broken payout. This is the clearest evidence in the batch.
Kriptoon – (BTC) Cloud Mining is published by Kriptoon Mining Studio. On the day we checked it showed 1.8 stars from 110 reviews, 10,000+ downloads, and both ads and in-app purchases. It is filed under Finance and was last updated on 23 July 2026. The developer also publishes KriptAxe – (USDT) Cloud Miner.
What the listing promises
From the store listing
“Secure Wallet Transfers — Payout your BTC safely anytime… No Hidden Costs — No deposits or hardware required to start… Payout your BTC to your Bitcoin wallet at any time.”
“No deposits required” and “payout at any time” are the two claims. The reviews address both.
Five withdrawals, nothing paid
Chris Grange, 8 September 2026:
A user’s account
“So as of now I have submitted 3 withdrawals, I have not received anything… there’s no support option and I haven’t been paid. The app did not let me upgrade to the $10 speed… and now have tried 5 withdrawals, no response.”
Note the sequence inside a single review: three requests, then a paid upgrade that failed, then five requests. He updated his own review as the failures accumulated.
Ten dollars for a plan that never switched on
Micheal B Oyegbade, 12 August 2026, six people marked it helpful:
“I have paid for $10 premium plans and yet it is not activated… it has been over 24 hours activation and yet no response from the customer care… I have reactivated for basic plan $5 and yet I haven’t got paid since yesterday.”
He paid twice. The second payment was an attempt to fix the first. That is the most expensive reflex in this entire category, and it is the one these apps are built around.
Nine days of silence
Steve Redwood, 13 August 2026:
“Withdrawal of daily reward is broken and for 5 days they said it was being checked by specialist and would be an update with problem fixed soon. That was 9 days ago and they haven’t answered my emails or by chat in the app.”
Put the three together and a timeline emerges. A payout path that stopped working in early August. Support that answered for a few days with a holding message, then stopped. Purchases that continued to be accepted throughout. And a user still submitting withdrawal requests into it on 8 September.
“No hidden costs” and the $10 speed
The listing says no deposits are required to start. Both reviewers above describe paid plans at $5 and $10.
The claim is technically survivable — you can indeed start without paying. It is the finish that costs money, and by then you are looking at a balance you want to release rather than a price you are deciding whether to accept. The word “start” is doing all the work.
1.8 stars is the honest number
Everywhere else in this series the rating is the problem: perfect fives, inflated 4.4s, ratings rewarded with hashrate. Here the rating is the one part of the listing telling the truth, and it is telling it loudly.
An app cannot fall to 1.8 without a large majority of the people who tried it concluding it does not pay. Ten thousand people have installed it anyway, because the rating sits below a green Install button and above a description promising secure wallet transfers at any time.
The sister app
Kriptoon Mining Studio also publishes KriptAxe – (USDT) Cloud Miner. When a payout path fails this publicly, a second app under the same studio with a different coin and a fresh rating is worth knowing about before it appears in your search results.
- Check the rating before the description. 1.8 is not a mixed reception, it is a verdict.
- Never pay again to fix a payment that failed. That reflex is the business model.
- Search the reviews for “withdraw”. It takes ten seconds and it is where these apps break.
- “No deposits required to start” describes the beginning. Find out what the end costs.
- Look at the developer’s other apps. The same operation usually runs several.
If you have paid for a plan here
Request a refund through Google Play now — refund requests are easiest while the purchase is recent, and one reviewer has already gone that route. Do not buy another plan to activate the last one. Screenshot the purchase, your balance, every withdrawal request and the support chat before they vanish. Report it at IC3.gov, and in the UK to Action Fraud. If you paid by card through Play, tell your bank and ask about a chargeback.
