Anyone who has stayed long enough in the crypto trading atmospshere will understand that this is not a new thing and the altcoin dump is not something common to all alt as there are some that will still break the odds and still increase. However, even the dumps also comes with its own window for one to buy in and invest because the downward trends is not something that will last forever.
Yeah sometimes it feels cryptocurrency market is a game of big whales ,
The number of coins traded sometimes could still easily pumped and dumped by a single trader ,
Speaking about when bitcoin get pumped and altcoin get dumped everytime ,
It's just an adjusment to the global price of cryptocurrency i think.
