There are only two possibilities, first that it will recover in time, and the other is the other way around.
CZ also clearly said that the MATIC team has nothing to do it. Regarding the big traders panicked and all. I mean, don't just ask the other to join the train when you're not even sure if it will recover or not. That's good it does recover, but if it doesn't?

Whichever it is, whether it's a manipulation or not, it'd be best to be careful when you see something like this. In case something similar happened again and you haven't sell your bag before the dump. On binance, the current matic price is around 250-ish satoshi. Still, the people who bought them before the price pump and sell it at the very peak was a very lucky ones.
