If DOGE is dumped and pumped just like that, maybe it's a bit easy and easy because previously DOGE's market cap was below the top 20 Coinmarketcap.
But what I am afraid of is the Pump and Dump of legendary coins like Ethereum and Binance coins, this is very scared, especially since the market cap of Ethereum is very large.
I am afraid of the impact on all the altcoins already circulating in all markets, including all tokens under the erc20 blockchain network.
