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
Traders are very disappointed that binance didn't immediately delist for Luna when a more than 100% plunge occurred (I know binance doesn't record a drop if it's more than 100%), as the biggest exchanges they should have been firm from the start to warn of an "alert" status for Luna trading , but all that has happened has harmed many investors/traders and hopefully it will be an experience for the future.
That's why now many Luna investors are losing their money.
Especially for those who bought without even feeling the slightest profit now they have to lose their money.
In fact, if Binance had given an early warning, maybe until now not too many of them have lost their money.
To carry out an early warning requires a lot of consideration and research in advance regarding the coin and the project. While Binance is an exchange that has a large list of coins, not just LUNA, it's highly unlikely that Binance will focus on LUNA alone. Not only Binance, I think other exchanges are like this too. Besides that, the price crash and the problems that occurred in LUNA/terra also coincided with the fall in the price of BTC and altcoins where many fell by more than 50 percent.
It should be the investors themselves who must understand and be aware before investing, or if they have invested, at least they know and update the news about LUNA, so that if something bad happens, the investor is able to take precautions regarding their investment.
