I never send them my btc, you can buy Minexcoin in some public exchange and store it in the Desktop wallet and not to their website unlike bitconnect in case you dont know.

Anyways, am not interested in debating obvious shills.
Am just saying it as it is.
Anyone who has an iota of common sense can see through the bs.
As to why they are showing their faces, probably because they are in some area of the world where they can just pay off the authorities to stay out of jail.
Enjoy your little scam.
Pikachu out.
