The alpaca hasn't fallen, it really has nothing to do with Binance, it's just that there are main players in Binance's spot price, and the main players' inventory is estimated to be at least 70% controlled. The alpaca will be taken off the contract in the last hour, and there will always be 30wu to 50wu of spot goods to buy 1 pallet, without a single oversized sell order hitting the market. The inability to fall is also within the trading rules. There is no problem with this coin security, and there is no wrongdoing. Everything is self matched by the market.
