Fraud Risk Assessment: CoinMining

  • CoinMining
  • Reviewed by: Digiconomist

CoinMining ( was launched in November 2020 providing Bitcoin cloud mining services. It is a full copy of another scam called BitcoinMining. The company’s legitimacy has been evaluated based on the items listed below. Every individual item has been checked for the presence of obvious red flags or warning signals. If these are present, an explanation detailing what triggered them has been included. A detailed description of the reasons to evaluate each of the included items can be found below the table.

Total Flags: 15 (3 Warnings = 1 Flag)
Phantom Riches The website advertises the “largest profits” and “fastest return on your investment”
Scarcity N/A
Source Credibility N/A
Social Proof Referral program awarding 10 percent commission. For a normal business this would represent a heavy blow to the profit margin, as it is paid directly from revenue and costs would still have to be subtracted.
Reciprocity Users can get a free 1250 GH/s trial upon signing up.
Guaranteed Return N/A
High Return / Low Risk CoinMining’s rates at the time of writing (0.00016 per GH/s) imply that an investment could be earned back completely in half a year. That would imply an unrealistic and unsustainable annual rate of return of more than 200%.
Overly Consistent, Positive Returns N/A
Downplaying Risks The website doesn’t feature any risk disclosure at all
Hardware Equipment
Public Mining Address No
Pictures of Mining Equipment None
Secretive or Complex Equipment Users buy GH/s lacking any significant description of underlying equipment. At best, the website features vague and meaningless descriptions such as “very cheap electricity with efficient custom made mining hardware along with modified mining software”.
Website Available Yes
Website Registration Details Registered November 14 2020
Website Design The website is a complete copy of another scam called BitcoinMining. The terms and conditions are still missing as well.
Grammar on Website Good, but completely copied (see Website Design).
Payments Options Bitcoin only
Service Disruptions & Unbusinesslike Conduct No terms and conditions (no legal basis for doing business). Reinvesting is strongly encouraged (there is even an option to do so automatically).
Contact Information No contact information (address or telephone number).
Verified Address The address could not be determined due to a lack of information. The website registration details have been hidden (whois privacy protection).
Verified Owner The owner could not be determined due to a lack of information. The website registration details have been hidden (whois privacy protection).
Business Registration At the very least a country of origin is required to find a business registration, but even this could not be determined.
Independent Audits None

Note that items with a warning instead of a flag indicate that these could occur at a legitimate company. For example, legitimate companies will normally try to persuade you into buying their products. Multiple warnings will, however, still trigger a flag. A description for the listed items is provided below. This list is meant to assist with identifying obvious scams, and therefore does not provide any guarantees that a company is truly legitimate.

Phantom Riches
The most common tactic used by fraudsters is called “phantom riches”. By dangling the prospect of wealth such as “big payoffs”, the scam artist tries to get you to stop thinking logically.

Using the fear of missing out, fraudsters create a false sense of urgency with statements such as “last chance” or “only so few available”. This causes people to agree hastily, before even having the opportunity to think about what they’re doing.

Source Credibility
Persuasion is more likely when the source presents itself as being credible, expert and trustworthy. Common tactics used by scammers to make themselves look legitimate include using fake websites or hacked emails and pretending to be someone they are not. Alternatively, sources can also be external with claims such as “Warren Buffet has already invested in this”.

Social Proof
Fraudsters take advantage of herd behavior by creating the illusion of consensus or social proof that the investment is legitimate with claims that “everybody is already doing it”, or referral programs in which members encourage their friends and associates to invest as well. This automatically triggers something in the head that says: “if everybody [or someone from the inner circle] wants it, it must be good”.

A business is likely to receive far more of our trust when it provides a lot of free value, because of the rule of reciprocity which causes us to tend to feel obligated to return favors after people do favors for us

Guaranteed Return
All investments carry some degree of risk, so a guaranteed profit is a clear red flag. A valid question would be why an organization would try to sell such a scheme instead of using it to get rich themselves.

High Return / Low Risk
Like a guaranteed return, a high return / low risk investment opportunity also defies the common risk-return relationship. The best advice is an old one: “if it sounds too good to be true, it probably is”.

Overly Consistent, Positive Returns
Cryptocurrency markets are among the most volatile markets, hence the performance of any related product or service is also expected to fluctuate.

Downplaying Risks
The fraudster will do anything to provide a false sense of security, such as presenting some form of external risk insurance for the investment. In reality, insurance is only seldom acquired and guarantees typically lack substance. Dummy companies are often used to act as the guarantor or insurer. Other actions may include misrepresenting, or even non-disclosure of risks involved.

Public Mining Address
A cloud mining company must have a public cryptocurrency address in order to participate in the mining process. There is no reason for a legitimate company not to disclose this.

Pictures of Mining Equipment
Cloud Mining companies should be able to provide some pictures of the products they are selling besides any textual descriptions.

Secretive or Complex Equipment
Even in the world of cryptocurrencies one should be skeptical about special competitive advantages without any proper disclosure, or when the information is incomprehensible or incomplete. Too often only the positive elements are accentuated.

Website Available
Considering the importance of domains and websites in the internet age, there is almost no reason for a legit company not to have one.

Website Registration Details
Very few scam websites survive longer than one year, so domains are generally registered for just one year unless otherwise required for the specific domain. For the same reason, websites created less than one year ago should be considered suspicious.

Website Design
Amateurish, cluttered and disorganized websites can point to a scam as many scam sites use text and images from legit websites and other sources which may not work together very well.

Grammar on Website
Many scammers have limited English proficiency.

Payments Options
Even though cryptocurrency payment options are logical for a cryptocurrency company, it is also very convenient for scammers as the recipient essentially remains anonymous. The same goes for services such as Western Union and Moneygram. Hence a lack of alternative payment options should still be considered a warning signal.

Service Disruptions & Unbusinesslike Conduct
Especially Ponzi scheme promotors will encourage participants to “roll over” their investment. These schemes are not very fond of investors cashing out, which may lead to difficulties receiving payments and a non-responsive or difficult to reach customer service.

Contact Information
Legitimate companies have very little reason not to list their contact information.

Business Verification
First, you should never hand your hard-earned money over without knowing where it is going. Second, you should do a background check to avoid handing it to a known scammer. Be weary of people without an online identity. Scammers will typically try to hide their identity or conceal their true identity to avoid being easily discovered.

Independent Audits
Audits certainly do not root out every instance of fraud, but auditors do have a responsibility to detect errors or fraud in the company’s financial statements.

Coinmama Bitcoin Exchange Review – Legit or Scam?

Updated on Oct 23, 2020 by Tuan Do

Coinmama is the Bitcoin exchange I use recently after reaching limits on the others. The exchange has been around for a while but I was hesitant to use it because I heard some complaints about their service. I gave it a try and here is the review.


Coinmama is registered in Slovakia but they offer the service worldwide. You might have limited functions in some countries but overall, the service is available in the widest range of countries.

Payment Methods

You can buy Bitcoin or Ethereum with your credit/debit card. I used my debit card to buy because it’s faster, however, it’s also more expensive.


I was quite disappointed with Coinmama’s customer support. The verification process was fast but when I had a request regarding my transaction, it took 2 days for the response. The good thing is that they explained thoroughly and keep me assured that I would receive my Bitcoin eventually.

Processing Time

The processing time varies depending on the workload. My first transaction went well and I received Bitcoin to my wallet in about 4-5 hours. The second transaction takes much longer and I didn’t receive my Bitcoin until 2 days later. There was a message saying: “Simplex, our credit card processor, are currently under heavy load. You may experience delays in processing your payment.

The 3rd transaction was completed within an hour when the service is less busy.

The price you see on Coinmama’s homepage has a huge markup because it includes the service fee of 8.5%. If you pay with cash, you don’t have to pay any more fee. But if you use your credit/debit card, you will have to pay additional 5% for Simplex, the payment processor. And that’s not all, I had to pay the currency exchange rate for my bank as well, so the transactions become so expensive. You should expect a 15% markup for your purchase.

Update: Coinmama now does their own processing which enables us to provide end-to-end support, and makes all transactions instant. The service fee is 5.50%, which is included in the prices on the website.


Overall, Coinmama is a legit Bitcoin exchange but I don’t recommend it because of the high fees. You should only use their service when you can’t buy anywhere else.
