Four out of five people who bought into Hunter Biden’s new meme coin saw their investments go up in smoke during the cryptocurrency’s spectacular launch-day collapse on Wednesday — even as one mystery trader turned a roughly $250,000 bet into $1.18 million within minutes, The Post has learned.An individual trading under a pseudonym spent about $250,000 to acquire 9,124 of Biden’s $LAPTOP tokens before unloading 8,480 of them minutes later for about $1.18 million, according a blockchain analysis by Datavault AI. That amounted to a gain of roughly $930,000 before transaction costs.Other traders weren’t nearly as fortunate.One buyer who plowed roughly $200,000 into the token near its fleeting peak saw the position dwindle to around $2,000 as $LAPTOP came crashing back to earth, according to Datavault’s analysis.“That’s the tragedy in these coins,” Datavault AI CEO Nathaniel Bradley told The Post while discussing investors who bought $LAPTOP at its eye-popping early prices.The token briefly shot above $300 during Wednesday’s chaotic debut before plunging to just a few dollars, wiping out more than 99% of its peak price within hours.“To come out and say that a laptop coin is worth $300 is, in my opinion, fraudulent,” Bradley said.Bradley characterized the launch as a “classic ‘rug pull.'”The term describes a crypto scheme in which developers or insiders extract value from a project or abandon it, leaving other holders with sharply devalued tokens.There has been no finding that Biden or the $LAPTOP project engaged in fraud or a rug-pull scheme, and Datavault’s analysis has not established that Biden himself sold tokens during the price collapse.Exactly how much Biden may have personally made from $LAPTOP — if anything — remains unclear.The project’s founders, including Biden, were slated to receive 30% of its 1 billion-token supply, according to the Wall Street Journal.Those founder tokens were set to be locked for six months and bec...
