Bubblemaps finally dropped the name. The “one of crypto’s largest KOLs” from last week’s teaser is Cupsey, not Ansem. Bubblemaps’ investigation alleges that Cupsey ran a 30-wallet operation that pulled about $1.74 million from copy traders in six months. The quotable version: Cupsey’s public Pump.fun wallet bought, his followers piled in, and twelve side wallets sold into them.
Two days ago I wrote about the Sahil Files and the Ansem rumors. Crypto Twitter had decided the target was Ansem. It wasn’t. That post still stands, because the Sahil beef is its own story and it is far from over. This one covers what Bubblemaps actually published, why the alleged scheme worked, and what it means if you copy trade anyone on Solana.
Who is Cupsey?
Cupsey is one of the biggest trading names on Solana. He is an ex Fortnite player who made millions trading memecoins in 2024 and 2025. His public wallet became a copy-trading magnet, and his $CUPSEY token rode that fame. He posts callouts, his followers buy, and copy bots mirror his public address within seconds.
Bubblemaps describes him as an aggressive trader whose strategy “took a darker turn” in recent months. The investigation starts on May 7 and runs to now. Everything below is Bubblemaps’ allegation, backed by their wallet mapping. It is strong on-chain work, but it is still one side of the story.
What Bubblemaps alleges
The thread found 30 wallets connected to Cupsey’s public Pump.fun wallets. Since May 7, those wallets traded more than 27,000 tokens. Around 3,000 of them went through what Bubblemaps calls a side wallet scheme.
The pattern
The sequence is almost always the same, according to the thread:
- Four operational wallets buy a token early and distribute it to twelve side wallets.
- Cupsey’s public wallet (6DQAGJ) buys the same token.
- Copy traders see the public buy and pile in.
- The side wallets start dumping.
In many cases, the selling started right after his public buy. So the order of exit was simple. Sell to the copy traders first, then to the social traders who saw the callout a few minutes later. Both groups thought they were trading alongside him.
The numbers
Bubblemaps puts the side wallet operation at $1.74 million across roughly 3,000 tokens. On top of that, Cupsey earned $331,000 in callout rewards. Those rewards come from launchpad programs that pay traders for bringing volume to a token.
The serial rugger connection
This is the part that goes beyond “KOL dumps on followers.” Bubblemaps found multiple on-chain links between Cupsey and a serial deployer with an address starting 3z4vj.
That deployer launched and rugged thousands of tokens. One of them was $CUPSEY itself. Cupsey’s side wallets sniped over 400 of those launches. The deployer’s trading profits sit at $1.3 million, per Bubblemaps.
Read that twice. If the links hold up, the trader’s hidden wallets were buying the first blocks of tokens launched by a known rugger, then selling to the audience that followed the public wallet. That is a different league than farming callout rewards. The lead came from @ogmothy, and Bubblemaps credited him in the thread.
Why the public wallet is the product
I have traded on Pump.fun for years, and I follow plenty of wallets. The thing most beginners miss is that a public wallet is a marketing asset. Everyone can see it, so everyone trusts it. Its owner knows that too.
A visible buy from a famous wallet does three things at once. It triggers copy bots. It signals the callout crowd. And it creates a liquidity wave that someone can sell into. If the same person controls other wallets that already hold the token, the public buy is the bait, not the trade.
This is the fourth Bubblemaps exposé of the same template. 0xEthan, Anglio, Solstice, and now Cupsey. Anglio even admitted to using the methods. Bubblemaps’ point last week was that side wallets have become a business model, and launchpads reward it with leaderboards, rebates, and callout bonuses.
It also connects to the Kimchi story from last month, where Bubblemaps traced the real profits behind a much bigger public number. Same tool, same lesson. The chain does not care what the influencer tweets.
What this means if you copy trade
Copy trading a wallet is not the same as copying a trader. You only see the wallet he wants you to see. Here is how I approach it.
Check the exit, not the entry. Anyone can post a buy. Look at how the token’s top holders changed in the minutes after a famous wallet bought. Bubblemaps and similar tools make this a two-minute check. Our Bubblemaps listing covers the platform and its rewards program if you want to learn the tool.
Watch for clustered holders. Dozens of fresh wallets each holding 0.5% to 1% of supply is the signature of bundled tokens. It shows up on a bubble map as one connected blob.
Treat callouts as ads. A callout with a referral reward attached is a paid post, whether or not it is labeled. Our guide on what social trading really is goes deeper on that incentive problem.
Run your own checks. The memecoin due diligence guide is the checklist I use before any size goes in. And if a deployer has rugged thousands of tokens, the rug pull guide explains the patterns to spot early.
What happens next
Three things to watch. First, whether Cupsey responds with his own on-chain evidence. A wallet-by-wallet rebuttal would change the picture. Silence or a vague denial would not. Second, whether Pump.fun and other launchpads act on Bubblemaps’ call to audit top traders and ban repeat offenders. Their referral rewards program is exactly the kind of incentive under fire here. Third, how $CUPSEY holders react, since the token’s own deployer is named in the thread.
Meanwhile, the Ansem question remains open. Bubblemaps named Cupsey, but the Sahil receipts about paid celebrity shills are a separate case. If you keep a list of meme coin KOLs to follow, this week is a good reminder to follow the attention and never the trade.

Nobody paid for this one either, and I doubt Cupsey will. If you trade the trenches, use a terminal that shows you holder clusters before you ape. I trade memes on FOMO and still use the original Pump.fun interface for launches. For the bigger coins, our OKX and Bybit referral links give you a sign-up bonus and keep this research free.
Final Words
Bubblemaps named a trader, not a shiller. That matters. The Sahil Files were about paid promotions in 2024. The Cupsey case is about hidden wallets selling into followers in 2026, plus a serial rugger in the mix. Different crime, same lesson. A public wallet is a billboard. Trust the chain, not the face next to it. If the allegations hold, the people who copied Cupsey were not riding a legend. They were the exit.
