Mercury Global does not and never will "work endlessly", it is a reboot of Mercury Mutual Fund which collapsed in 2016 and will collapse in due course itself.
Mercury just has suspended its activities in 2016 because bank accounts of community participants were frozen. This is not a community scam, it is a
scam of banks. Now the community does not cooperate with banks. Despite this all lost funds of participants converted into the cryptocurrency. This proves once again that the banking system has outlived itself and has lost confidence
This phase of the scam is usually heralded by signs of an exit strategy, for example when participants are encouraged by discounts or premiums to send funds outside of the normal accounting procedure, directly to the personal account of the admins.
The community periodically provides discounts or premiums to its members.
