Usually the scammers dont stick with a single coin as once the profit is made, they stop logging into their account and move on to their next scam.
He hasn't stuck to a single coin. He collaborated with Jasinlee and Fibonacci on 2 other pump and dump coins. Kalgecin was involved in Pesa and at least one other that I know about. Who knows how many other others there are.
Give them any background you might have...
