Verdict up front: a user found that BTC Mining Cloud Pool – PRO’s withdrawal form accepts only numbers in the wallet field — and every real Bitcoin address contains letters. The listing’s own feature list includes “Cloud Mining Pool Simulation”, and its gallery shows a “Bonus for 5-star review”.

The wallet field
Marlin Dailey, 14 April 2026
“Withdrawal is NOT possible… The wallet space to input only allows numbers, not a combo of letters and numbers. All my wallet addresses have a combo of letters and numbers.”
A Bitcoin address always contains letters. A withdrawal form that rejects letters cannot accept any real address. Peter von Thenen, 7 July 2026, found the same thing: “Fake Simulator application cannot withdraw, would not accept wallet address” — and advised others to read “About this app” before “wasting your hard earned upgrades”.
What “About this app” actually says
The description opens with “Explore Bitcoin Cloud Mining Like a Pro”. Further down, in a list of key features, sits the phrase “Cloud Mining Pool Simulation”, next to “Earn in-app bonuses” and “Referral Rewards & Bonus System”.
The gallery tells the other story: a Transfer Balance screen offering Binance, Trust, Coinomi and Coinbase as destinations, an “Upgrade Plan” button, and a “Rate Us & Earn Bonus!” card.
Paid five-star reviews
The history screen on the gallery includes an entry reading “Bonus for 5-star review”. Rewarding users for ratings is prohibited by Google Play policy, and it matters here for a specific reason: it inflates the 4.4 average in one direction only. gurpreet singh, 6 June 2026, put it bluntly: “People who give 5 star ratings to get rewards, this is a scam app, there will be no payout in it, the wallet is not even valid for it.”
More than one listing
Rare Studio’s developer page also lists BTC CLOUD MINING FARM and Btc Mining Cloud Pool — the same theme, the same developer. If one of them has taken your money, check whether you have installed the others.
Before you pay any mining app
Four checks take less than two minutes. Read the full description for the words simulation, virtual or for entertainment. Find the withdrawal minimum and compare it with what one day of “mining” adds. Look at the Play category and the developer name: a mining app filed under Tools or Productivity, or published under a personal name or a string of keywords, is avoiding scrutiny. Then sort the reviews by newest and read the one-star ones about withdrawals. If none of those checks passes, the only safe amount to spend is nothing.
- Type a real wallet address into the withdraw form before buying anything. If it will not accept it, you have your answer.
- “Rate us and earn a bonus” means the average rating is not independent.
- A feature list that says “Simulation” overrides everything the gallery shows.
- Real exchanges in a dropdown are just names on a screen.
If you have already paid
Cancel any subscription in Google Play (Payments & subscriptions), not inside the app. Request a refund through Google Play while the charge is recent. Screenshot your balance, the withdrawal screen and every purchase before anything changes. Then report it at IC3.gov, or to Action Fraud in the UK.
