Or is he trying to combine his coins for when people start to massively withdraw from his scam exchange so he can charge his users massive fees
I just checked their current BTC withdraw fee and found it's 0.001
BTC (about $16.9). I'm sure the fee was 0.0005
BTC or lower few months ago. It's unlikely they perform consolidation with such high fees, so your speculation could be right.
It seems that Binance is trying to do some tricks now and they are trying to take everything in their hands. And since the bankruptcy of FTX they have got another big opportunity to do their job and they want to dominate the market alone. And they are trying to increase their reserve fund by taking huge profits from the current market using several other strategies including high Withdraw fees so that they never end up in the same situation as FTX. CZ_Binance is a very smart guy
