He is back..... 
hey @mk4 how are you? these guys missed you.
He was mentioned few days ago by Shun [Proclaimed Cryptoaidrop King] in his FB post. At first, I was shocked because the name mK4 reminds of a creative and knowledgeable user of BTT.hey @mk4 how are you? these guys missed you.
Maybe he is just busy with his own craft. But if you follow his page in Facebook, one thing is clear. He is still in cryptoverse!
