How crypto futures markets are feeding ‘scam coin’ insider pump and dumps

RAVE experienced a surge in valuation, reaching $6.7 billion on Apr. 18, only to crash by nearly 95% soon after. The token’s market dynamics, including a concentrated supply, thin float, and live perpetual market, contributed to both the rapid rise and fall.

An investigation by ZachXBT revealed that insiders held over 90% of RAVE’s supply, with a significant portion concentrated in one wallet and the rest spread across two connected wallets.

Both Binance and Bitget publicly acknowledged that they were investigating the situation, while OKX’s Star Xu confirmed that their risk engine did not detect any disruptions. Additionally, OKX offered a $25,000 bounty to support ZachXBT’s investigation.

RaveDAO denied any involvement in the incident.

The mechanism

What traders refer to as \”scam coins\” often involves a repeatable derivatives structure.

The cycle begins when a token with a concentrated supply and a small float enters a perpetual market. Bearish traders take short positions, and a small movement in spot liquidity triggers forced buying, causing the price to skyrocket.

When the token’s valuation rises significantly, holders of concentrated supply sell into the forced demand.

Binance’s market maker red flags guide from Mar. 25 explicitly warned about coordinated sell-offs, mismatched volume and price behavior, price spikes in low liquidity, and shallow order books that make prices susceptible to manipulation.

Post-crash data from CoinGlass shows approximately $3.36 billion in 24-hour futures volume for RAVE, compared to $138.9 million in spot volume, indicating a 24.7x derivatives-to-spot ratio. Open interest accounted for about 67.3% of the market cap.

With most of the supply unable to trade, RAVE’s open interest surpassed the market value of its tradable float.

Based on CoinGlass’ post-crash price of around $0.625, a 15% float of a one-billion-token supply equates to approximately $93.8 million, lower than the $105.7 million in open interest.

While this data doesn’t prove manipulation, it highlights a market where derivative exposure exceeds the underlying cash market.

The same structure for three different tokens

On Mar. 23, SIREN’s open interest peaked at around $105 million before dropping to $65 million as short positions faced liquidation. Binance and Bybit reported about $7.1 million in liquidations during this period.

Despite the initial squeeze, over 59% of positions remained short, leaving the market exposed to another round of forced covering.

Phemex identified a wallet cluster controlling about 88% of SIREN’s supply and noted an extreme crowded-short signal with a funding rate of -0.2989%. CoinGlass data now shows SIREN’s futures-to-spot turnover at approximately 40.5x.

A deeply negative funding rate means short holders pay longs to keep their positions. When combined with concentrated supply and low float, price discovery shifts to the derivatives layer, allowing those in control of the cash market to manipulate prices.

ARIA exemplifies the aftermath, as suspected manipulators sold 45.64 million tokens for approximately 5.42 million USDT, causing the token to plummet by 91%, reducing its market cap from around $315 million to $38.5 million.

Despite the crash, ARIA’s futures-to-spot turnover remains at about 12.0x, with open interest representing approximately 77.7% of the remaining market cap.

RAVE, SIREN, and ARIA showcase a similar investigative structure, ongoing squeeze, and aftermath at three distinct points in time.

The infrastructure enabling the most effective moves in each episode runs through venues that had already published guidance explicitly describing those very moves.

Binance’s Mar. 25 guide and its public acknowledgment of the RAVE investigation both come from the same institution managing the same business tension. Listing volatile, thin-float assets with perpetual markets generates fee revenue at scale.

The 24.7x, 40.5x, and 12.0x futures-to-spot ratios for RAVE, SIREN, and ARIA also represent revenue figures. Futures volume on RAVE alone hit roughly $3.36 billion in a single day post-crash.

Exchanges can point to surveillance and investigation as evidence of responsibility, while retail traders can point to the listings themselves as evidence of the opposite.

Two paths from here

If venues adopt float-aware listing standards, with minimum circulation thresholds, wallet-concentration screens, and lower leverage caps on thin-book assets, the frequency of these episodes drops.

Binance’s Mar. 25 red flag framework already gives exchanges a ready-made rationale for such requirements.

The constructive case rests on RAVE becoming the episode that moves listing standards from informal guidance to enforceable policy, because the reputational cost of another high-profile investigation finally exceeds the listing fee revenue.

The opposite path is equally coherent, as the incentive structure that produced RAVE, SIREN, and ARIA is intact. Concentrated holders can repeatedly use exchange deposits, narrative catalysts, and crowded short positioning to force liquidations.

A separate CoinGlass market share report found that crypto trading activity in the first quarter was still overwhelmingly concentrated in derivatives, with roughly $18.63 trillion in derivatives volume versus $1.94 trillion in spot volume.

If no hard float or depth requirements emerge, the practical warning sign for traders becomes a recognizable cluster consisting of top-wallet concentration above 80%, futures-to-spot turnover crossing double digits, extreme negative funding, and price action that corresponds to no identifiable catalyst.

That cluster describes what the three episodes had in common: one wallet cluster controlling an outright majority of supply, real tradable float governing price sensitivity, exchange deposits tied to project-linked wallets preceding the rally, and withdrawals arriving during the forced bid.

Retail shorts who identify that concentration, do the on-chain work, and position correctly can still be right on every fundamental point and lose because their timing is exposed to forced buying they cannot predict.

That asymmetry is a feature of listing perp markets on assets where a small number of wallets can dictate the effective supply available to the cash market.

Major venues have now publicly acknowledged that at least one such episode warranted an investigation.
