I didn't search very deep and managed to find all of those addresses that sum-up to 16506.9152708 BTC which equals to 332,548,315$ USD

Does anyone know what this could possibly be? Is it bots trying to "launder" Bitcoin?

I think it could be related to some mixer's funds if they're still active.
It could also be more likely that these addresses are related to exchange, more likely finance, I could be wrong here as I don't know the addresses binance uses.
