No, the dev team is not split. An old admin that left the team months ago came back trying to get things his way. Unfortunately, he was the creator of the telegram channel and banned ALL the current dev team.
This is why the dev team had to create a new telegram channel. There is no split as the old admin has no say or power over the project, he only has the old telegram channel full of bots!
As far as I know there is no development by the old channel, just promises, and anyway they haven't got any control over official page, private keys or social media so they cannot represent the eBTC community, not that we would want to have such a shady person on the dev team...
Our dev team remains very active! Always bringing many news! Recently they pulled out a free airdrop of a partner token for all eBTC holders! (Already finished). Just amazing!
