Any update on this Project?

Bought one M31S recently. Received miner in good condition last week.

Recently I  was scammed by an Monbux Escrow impersonator in Telegram.

Seller  is a member here.
seller contacted me via PM and started conversation in Telegram.

Once deal for purchase of 4 miners was finalized Seller contacted escrow in telegram.

Total BTC lost: 0.18426

I have sent PM and email to monbux on May 18 and received reply today that the Telegram escrow was impersonator.

The Impersonator in Telegram is still active and contacting me every day that i need to send him 0.1 BTC in order to get refund . According to him this is the escrow rule. Members here can elaborate if that is the case.

Monbux should reply to my PM and emails promptly.  This is how he wants to be contacted according to this thread.

To all members here Please do not try to engage any Escrow without properly following the contact methods outlined by the respective Escrows.

Trade Safe.

Are these brand new units? or coming off of a active/about to close mine

I might be interested for some or all miners.

I must be able to test and pickup the miners. I drive by Quebec City often so willl be able to pickup. Please post city name where miners are.

Please allow to accept newbie PM, so i can PM you to discuss price.
