Do you have Birthday? Then ECOS will provide you with a Birthday present!?
Buy any Bitcoin mining contract during your Birthday week (3 days before your Birthday, the Birthday itself and 3 days after your Birthday) and get extra 7 days added to your purchased contract!?
All you need to do is to send a proof of your Birthday to ECOS HelpDesk (ID or Passport with your date of birth) and the present will be added to the contract that you indicate.
Happy Birthday and enjoy your bonus mining days!
