The bewilderingly fast rise of pepecoin (PEPE), a meme coin introduced mere weeks ago that’s now worth more than $1 billion, is making gigantic fortunes for those undeterred by warnings this is a fad that will end badly.A perfect example: a pseudonymous trader named dimethyltryptamine.eth spent $263 just three weeks ago to buy trillions of PEPE tokens. That former pittance has turned into $3.8 million in profits from tokens they’ve already sold, and their remaining holdings are worth about $9 million, according to data by blockchain research firm Arkham Intelligence. That’s an almost 5,000,000% profit.The trader is benefitting from the breakneck rally of a coin based on the “pepe the frog” meme, a popular symbol in crypto circles. Launched in April, the meme coin’s market capitalization astonishingly surpassed $1 billion on Friday and, according to Gecko, at one point was worth more than Arbitrum’s ARB, which is also among the hottest newly issued tokens of 2023.

Analysts, however, have raised concerns about the concentrated ownership of pepecoin, pointing to a handful of traders acquiring substantial amounts of PEPE when the token was released last month. Blockchain sleuth Lookonchain unveiled five accounts connected to a wallet belonging to pepecexwallet.eth, which received funds directly from the token’s deployer contract, acquired over 8.87 trillion PEPE after issuance for just $385.Dimethyltryptamine.eth, which wasn’t cited among the insider wallets by Lookonchain but belongs among the earliest buyers, purchased 5.907 trillion of PEPE tokens for $263 in two transactions on April 14 using UniSwap, Arkham shows. The trader also paid $17 for gas fees.Since then, the trader has been gradually taking profits by sending smaller amounts multiple times a day to UniSwap, and receiving ether (ETH) in exchange. The wallet has sent $3.8 million of PEPE to UniSwap in the past month, per Arkham data, presumably to take profits, with $2.4 million of that transferred in the past 24 hours.
