Binance and many other exchanges are SCAMEERS they are INVOLVED with LUNA SCAM
They didn't delist till it drop to ZERO even that they know LUNA devs was creating
more supply and dumping in their Platforms those platforms just trying to collect more
FEES and don't care about the investors
I don't know if they were involved in Luna's recent dumping because when a large amount of tokens were transferred to their exchange they were definitely informed. But don't blame the exchanges because they are business people and they need profit, If you are to blame, blame yourself for being too greedy when trying to buy dip luna when the price is on the decline and expect it to recover to make a profit. Unfortunately, that didn't happen and resulted in thousands of traders losing money.
