Minex was nothing but a ponzi scam. The word "interest" was changed by a bullshit called "Parking"
Daily: 0,5%
Weekly: 4%
Yearly: 70%
The card scam was added just to give some more credibility to the ponzi scam and now, that dudes are sending out cards, under the name of tableware trading company and of course that cards are not working.
Conclusion
1. Minex = PONZI SCAM
2. Minex = Card fraud
3 Minex = Bunch of Russian and Ukrainian scammers that will go to the jail, or meet some other Russian dudes, who invested in this scam and lost money (Going to the jail is more preferable believe me)
A user on their censored thread are saying the cards are working now. Is that true? One claimed to have purchase things online from a retailer but I am skeptical.
I ordered some drills from Aliexpress, my card work

next week will try ATM withdrawal
These "cards" are obtained using falsified data, issued through shell company UAB KRISTOLINIS DUGNAS to cover its true identity,which is major breaking of AML laws, Upaycard,Mastercard and FCA rules and regulations. As every criminal endevaour,it may work at start,but not for long. The moment theirs cards are started to use, time is start to ticking. If not caught because of using falsified data,they will be caught by Mastercard who is monitoring cards location of use. The moment they spot prevealed using of cards in countries for which Upaycard has no license, they will put red flag on cards and cancel them.
Unfortunatley, Boris and his team does not care for consequences to users which will face account freezing.They wrote in TOS how they are not responsible for anything about cards. Like in Instabuy case,where they are relentlessly selling coins ,busting price of MNX completely and making major damage to investors, they are willing to push illegal payment card program to the bitter end ,just to squeeze every single dollar or euro from his customers pockets.
