.... i would like to hear what you guys think...
I can assume that these wallets that the OP indicated belong to the Binsnce exchange and, accordingly, they contain BNB coins of exchange users. But in any case, a lot of coins are in the possession of the exchange team, which were released in 2017 and partially unblocked this summer.
It's really obvious that the exchange will have the highest amount of their coins since they haven't released some of it yet. Especially those coins that will gonna be sent to the burning address. I don't think to have any doubt about BNB and the Binance company right now, they are already in their long run.
They won't gonna turn the table just for their benefits except they will update their platform in the future to give their users fully convenient and user-friendly services.
If I'm not wrong, they've just burned some tokens just a few weeks ago.
