is airdrop still active .if yes how can i join ?
No. The airdrop has been ended since month ago. So many newbies and junior members in this thread... Guys, you all have been scammed. This coin has no real value and cannot have any real value, and was not even intended to have any real value long term. This all had only one purpose - make the developer rich quickly. 
This one, i fully agreed with this. Now eBTC only worth $0.1 just like other shit token
