A mysterious trader turned just $304 into a staggering $482,000 by flipping the newly launched Bubb (BUBB) memecoin—just before it crashed over 50% in value. The lightning-fast profit, netting a 1,586x return within 24 hours, has sparked intense speculation of insider trading across the crypto community.

On-chain tracking platform Lookonchain revealed the trader bought nearly 44 million BUBB tokens, selling a portion for $122,000 while retaining the rest, valued at $360,000—right before the token's market cap plummeted from $43.7 million to $22.6 million. The timing of the sell-off, coupled with its scale, drew sharp criticism online.

Fueling the buzz was an X post from Binance co-founder Yi He, who commented on a BUBB thread on March 20. Traders interpreted this as a potential nod to a Binance listing, which helped drive up the hype and price.

The incident mirrors last week's collapse of the Wolf (WOLF) token, a memecoin inspired by the "Wolf of Wall Street" and promoted by influencer Hayden Davies. WOLF briefly hit a $42 million market cap before crashing 99%, with 82% of the token’s supply tied to one entity.

Even more disastrous was the politically backed Libra token, endorsed by Argentine President Javier Milei. It turned into a $100 million rug pull, wiping $4 billion in market cap and triggering impeachment calls from lawmakers. Reports found eight insider wallets had cashed out $107 million before the collapse.

Analysts are calling for stronger launch protocols and anti-whale safeguards to prevent future exploitation and protect retail investors from being caught in orchestrated pump-and-dump cycles.
