You are new to the market? Maybe it is a need for you to be aware of the situation where the market is volatile and you can expect and experience this all the time.
I'm uncertain as to what the reason causes of this dump as usually whales did this but to hear no info of such transactions that is why I could say this was just a normal market correction and we need not make a deal with this but to keep calm and easy. To have fun with the other stuff outside crypto will really give us ease.
