If anyone wants to see the status of the Endowment funds, including a complete list of all the Endowment wallets, check out this post: https://bitcointalk.org/index.php?topic=4870374.msg43864610#msg43864610.

TL;DR: about 80% of the coins mined for the Endowment in 2017 are still in their original wallets. Those who claim the BTG team "dumped" are contradicted by evidence that's been easily available on the blockchain every day since last year. Anyone can look and see for themselves, but these people are apparently not interested in the truth.
