Unable to access the website

Unable to access the website? I'm fairly certain that they have finished our holdings and are currently releasing additional variations. Finding a company that delivers is uncommon. However, HILLY periodically demonstrates that it is their requirement for on clock payments

It wasn't a good experience that I had with this firm because they are full of many promises, but they will never fulfill anyone of them. I've learnt my lesson the hard way and don't try to invest here or else you will lose it. I wouldn't recommend them to anyone. I recommend PAIVA. They constantly pay.

They are big thieves and full of different ways to cheat on people's money and then let them down later on. They will always try to act like they are real, but they are not, and they are just time wasters. So, I wouldn't recommend them to anyone. I recommend PAIVA. They do pay.

SCAM WARNING: DO NOT INVEST IN marmining.com

I invested a total of over $5,000. After my first investment, they allowed a small withdrawals to lure me into investing more. I then invested another large amount. When I attempted to withdraw, they demanded that I pay an additional money before processing my withdrawal, which I refused. Now site gone offline with all investors money.

The website address is not a legitimate business address. Most of the reviews they have online are also fake, likely posted by themselves to appear trustworthy.

I have reported this scam to the following authorities in the USA:

Federal Trade Commission (FTC)
The Internet Crime Complaint Center (IC3)
The Securities and Exchange Commission (SEC)
In the UK, I have reported them to Action Fraud.

DO NOT INVEST. THEY WILL TAKE YOUR MONEY AND THEN LOCK YOU OUT.

I will continue to update this review as I work with the authorities to get more attention on this scam.

Big scammers…

Big scammers…. “The system discovered that an abnormal amount of US$2,000 was deposited into your account. The system automatically restricted your withdrawal function. You will have to wait until the system financial settlement is completed on October 1 before it can automatically return to normal” This is customer support said. On 27th September 2024 – MAR Mining has collpased. As at the time of this update MAR Mining’s website is no longer accessible. Many investors money had gone, no action had taken to this marmining company. Even though we had reported to “actionfraud.police.uk” is useless. Happy ending for this marmining company had taken all investors money.

Avoid them at all costs!

I've said it: they're liars and a bunch of thieves taking advantage of people's money. If you put in money here, you'll lose it because I'm speaking from experience. Choosing to move on with PAIVA has been a blessing in disguise so far.

I should have listened to my friend

I should have listened to my friend, but I still deposited $400, and now they've closed! I have been in some very good cloud mining projects and i should have stayed with them. For now, i'm only investing with HashMirage platform, they pay instantly and never delayed any payment.

Absolute scam.

Blocked withdrawals and was told would be open again on 1st October. Meanwhile asked me to put more funds in so I could fulfil a contract. I knew at this stage that they would disappear before October 1st so cut my losses. Watch out for this ponzi model. No doubt they will appear again under a different name.

SCAM!

SCAM!! DO NOT UNDER ANY CIRCUMSTANCES TRUST THIS WEBSITE!! It seems when MARMining makes a mistake, and customer service has no idea what happened. MARMining locks your account, and "The customer" is supposed to deposit funds to correct "MARMinings" mistake. Simply put, it is a SCAM. I had deposited funds in early June, 2024, and had been "rolling" the funds for 4 months. The account had gotten to about $3,000. Then out of nowhere, $1,000 was "abnormally" deposited into my account. When I pointed this out, my account was locked for any withdraws, and " I " had to deposit $1,000 to correct "Their" mistake. Because "they" could not withdraw the funds that "they" placeed into my account. Allegedly, it turned out to be a "dividend" payment, that customer service apparently knew nothing about, yet, my account was not unlocked.
When I came here and posted it was a SCAM, MARMining challenged the posting, and they completely closed my account, in turn, "STEALING" my money. MARMining will not answer any emails. and the "Online" customer service chat box, has disappeared. DO NOT TRUST THESE PEOPLE WITH YOUR MONEY!!
