Since the exchange had sales volumes so large that only developers could do this ... but this is my personal opinion, maybe things are different.
If they wanted to leave then what was the purpose of the swap and introduction of Aigar ? I think the team is working on the issues and i think they should announce the continuation of BTW tokens until all the issues for the Aigar tokens and site is resolved. I would still like to hear the official word from the team.
Let's not forget that the swap of coins occurred at the rate of 1Aigar = 60BTW. That is, most of the premine remained with the developers and they sold it safely.
What do you mean by development team sold the coins, Are you referring to Aigar or BitWhite ? Also the price of bitwhite is constant at 11-12 Sat (https://coinmarketcap.com/currencies/bitwhite/) for a long time ,which means that the project has still live in it and not everyone has sold out yet.
