The Dogecoin and Shiba Inu prices have crashed violently, down over 7% in the last 24 hours.This price decline is a result of Melania Trump launching her meme coin 'MELANIA', causing a sell-off in other coins.The launch of 'TRUMP' meme coin by Donald Trump also contributed to the crash.Despite the crash, accumulation of meme coins by crypto whales suggests a potential bullish reversal.
