Ripple CTO emeritus David Schwartz has issued a stern warning regarding the latent risks inherent in copy trading, a cautionary note he shared on X, responding to a conversation initiated by Coin Metrics co-founder Nic Carter. The discussion was sparked by an X user's extraordinary claim of transforming a mere $12 into $100,000, achieving an astounding 8,300x return. This feat was purportedly accomplished by consistently going all-in and doubling their bankroll 16 consecutive times on short-term Bitcoin (BTC) movements, all while openly sharing their trading decisions and underlying rationale.

Nic Carter immediately identified this scenario as the "oldest trick in the book," proceeding to meticulously deconstruct how such deceptive schemes operate. He elucidated that individuals perpetrating this scam typically establish dozens, or even hundreds, of separate trading accounts. On each of these accounts, they execute highly risky trades – in the described case, repeated all-in coinflips on a daily basis. While the vast majority of these accounts inevitably go to zero at an exponential rate, a select few manage to survive. Carter posited a win probability of approximately 50% per round and illustrated that with around 100 accounts, it is statistically probable for one account to achieve seven consecutive wins. The deceptive trader then selectively reveals their single winning account, leveraging its success to persuade others to engage in copy trading, thereby "farming" them for profit.

Carter further highlighted the historical precedence of this particular scam, noting its earliest recorded instance dating back to the 1870s. In that era, fraudsters would dispatch letters containing diverse stock tips to a large populace. By culling those who received incorrect predictions, they would then focus on the few who received accurate advice, convincing them of their infallible stock-picking prowess. This historical context underscores the enduring nature of such manipulative tactics.

Joining the conversation, former Ripple CTO David Schwartz reinforced the gravity of Carter's warning, pointing out that this copy trading trick is often pulled unintentionally by many. Schwartz observed that individuals caught in this scenario frequently harbor a genuine belief in possessing a unique trading "edge," when in reality, their perceived success is nothing more than pure luck. His crucial insight underscores the inherent challenge in copy trading: "The problem with choosing copy trading is that it's all but impossible to avoid following someone based solely on past luck."

In light of these revelations, Nic Carter issued a crucial piece of advice to the broader crypto community. He cautioned that if anyone is ever promoted based on their trading track record from a "liquid book," it is imperative to verify that it is indeed their sole trading account. He urged potential copy traders to insist that the individual commit to using a single account and then diligently monitor their performance on a go-forward basis to ascertain genuine skill over mere fortune.
