Changpeng Zhao, better known as CZ, is no stranger to headlines. But his latest one — opening a leveraged long position on a little-known token called Mubarak — has stirred up fresh chatter across crypto Twitter. And now, he’s addressed it head-on.
In a short statement, CZ clarified that he wasn’t betting big or signalling anything. “Today, I conducted the first on-chain perpetual contract test,” he wrote. Just an experiment, he insisted. “I’m just trying to experience it, and also want to see if there are still any MEV [maximum extractable value] problems.”
He added something that surprised even veteran followers of Binance: “It may sound surprising, but I’ve never traded a contract on Binance [CEX],” he said. That’s right — the man behind one of the world’s biggest exchanges claims he’s never placed a derivatives trade on it. “I’ve seen many product demos,” he said, “but never clicked the button myself.”
The trade: 0.04 BNB, 24.7x leverage, all eyes on Mubarak
So what exactly happened? According to reports, CZ used a public donation wallet to open a leveraged long position — 24.7x, no less — on Mubarak, using just 0.04 BNB. That’s around $20 at current prices. The position didn’t last long. It’s already been closed.
Yes, $20 is pocket change to CZ. But when that trade came to light, it lit up speculation.
Was it a test? A statement? A wink to insiders?
Turns out, it really was just a test — if we take CZ at his word.
Coin spikes and speculation flies
Of course, in crypto, even tiny moves by big players can cause shockwaves. Shortly after the trade became public, Mubarak rose by 5.5%, going from $0.146 to $0.154.
Meanwhile, APX — the platform hosting the perpetual contracts — surged even more dramatically, jumping 26% from $0.64 to $0.81.
Was it coincidence? Maybe. Was it reflexive hype? Definitely.
One-sentence paragraph: Traders don’t wait around to verify motives.
Here’s what moved in the wake of the test:
-
Mubarak: +5.5% gain after news of CZ’s test
-
APX Token: +26% rally following sudden visibility boost
What is APX Finance, anyway?
For those not glued to DeFi forums, APX Finance is an emerging platform offering fully on-chain perpetual contracts. Think of it like dYdX, but smaller, newer, and more nimble. Built on BNB Chain, it focuses on keeping trades visible on-chain and reducing front-running — which is where the MEV comment from CZ comes in.
Maximum Extractable Value, or MEV, refers to the value blockchain validators can squeeze from reordering or inserting transactions. It’s been a thorny issue in DeFi, especially for newer protocols. If CZ was checking for MEV flaws, it makes sense that he’d try it on a low-volume, new-gen product like APX.
But here’s the twist: APX is tiny. And suddenly it wasn’t.
The community’s mixed reaction
The crypto crowd didn’t all cheer. Some users praised CZ for “walking the walk” by trying out a DeFi product hands-on. Others felt it was clumsy or potentially misleading, especially since the trade was placed from a donation address.
One user wrote on X (formerly Twitter): “This is how coins pump these days? With a $20 trade and some accidental hype?”
Another quipped: “CZ just accidentally did more marketing for APX than their whole team this quarter.”
That’s crypto for you — even experiments can cause tremors.
What this says about CZ — and Binance
This mini-event also opens a curious window into CZ’s relationship with trading. For a guy who built a trading empire, he doesn’t seem to trade much himself. Not even on his own platform.
That kind of detachment is rare in crypto, where founders often double as whales or degen traders. CZ’s statement could be read as intentional neutrality — or maybe just a philosophical choice to stay above the fray.
Still, the fact that he used a public address that’s tied to donations and prior activity raises eyebrows. Transparency? Sure. But also: visibility. And with visibility comes speculation.
One thing’s clear — even micro-trades by CZ don’t go unnoticed.
The numbers don’t lie — even small actions move markets
Here’s a look at the immediate market impact after CZ’s test trade was discovered:
Token | Price Before | Price After | Change |
---|---|---|---|
Mubarak | $0.146 | $0.154 | +5.5% |
APX Token | $0.64 | $0.81 | +26.5% |
The APX rally was especially notable. A product test ends up doubling as a marketing event — not bad for a Tuesday.
That said, CZ has yet to comment further beyond his original message. No word on whether he’ll run more “tests.” No hints about whether he liked what he saw.
For now, all we’ve got is one trade, one message, and two price spikes.
But hey — in crypto, that’s sometimes enough to set off fireworks.
