The altcoin that had been turning heads has since recovered some ground, but the damage is still severe. We break down what happened.
SIREN, a meme and AI-agent token on BNB Chain, crashed from $1.30 to $0.05 over the weekend of June 13-14, 2026.

The culprit: a single address controlling the vast majority of circulating supply sold roughly 670 million tokens in 48 hours. That’s about 92% to 94% of the entire float.
According to Spot On Chain and Lookonchain, the whale raked in about $64.8M in USDT. Around $25.7M of that has already been moved to centralized crypto exchanges (CEX) like Binance, Gate, and KuCoin. The rest remains on-chain but scattered across hundreds of addresses, making it harder to track.
At the time of publication on June 15, 2026, SIREN trades at about $0.05555. The 24-hour drop is nearly 37%. Over the week, it’s down more than 95%. Market cap has collapsed from multi-billion-dollar peaks—it briefly hit $3.61 per token in March—to roughly $41M.

The sell-off triggered a surge in trading volume to $191M in 24 hours. According to CoinGlass, futures volume for SIREN topped $625M over the past day, with liquidations hitting $3.4M—more than $2.7M of that from long positions.
Analysts called it a classic pump-and-dump. Even before the crash, on-chain researchers including ZachXBT and Bubblemaps had warned that a single cluster controlled nearly half the supply, and that some wallets were linked to DWF Labs.

What to Expect From the Crypto Market in June 2026
The SIREN incident has once again exposed the problem of meme and AI tokens with extremely concentrated supply. The whale still holds about 595.7 million SIREN, roughly 82% of the circulating supply according to Lookonchain—meaning further price pressure is still possible.
Still, the broader altcoin market held up on June 15. Activity rotated into more resilient assets like Zcash and Near Protocol.
