My first experience with high-frequency trading on a mobile device was actually out of necessity.

That day, the market suddenly moved, and I took out my phone on the subway, placing orders, canceling, and placing new ones. The result was either slippage or lag, and in the end, the price had already moved beyond my ability to catch up. At that moment, I realized one thing clearly: it's not that I don't know how to trade, but that many mobile trading apps simply can't keep up with the real market.

Later, I started using @easydotfunX, and the difference in experience was very obvious.

Many trading apps on mobile share the same issues:
Insufficient depth, looks like it can fill, but gets eaten up when you tap;
Noticeable latency, by the time you react, the opportunity is gone;
The so-called "fast in, fast out" often relies more on luck.

But easyfun gives me the feeling—it's not just a "barely usable mobile app," but a tool genuinely designed for trading.

In terms of depth, it’s basically on par with top CEXs.
Prices are displayed as if they are really there.
A tap, and the trade executes immediately—no extra steps, no emotional interruptions.

Speed is even more critical.
Whether it's small fluctuations in spot trading or opening high-leverage contracts, the entire process is almost real-time feedback.
You can feel it: the market moves, and you move in sync.

And all of this fundamentally depends on Hyperliquid.
Without its low-latency, high-throughput on-chain perpetual mechanism,
such "instant confrontation and real-time execution" experiences would be impossible.
This isn't about UI aesthetics; it's determined by the underlying architecture.

Another feature I personally like is Copy Trading.
In the past, if I wanted to follow experts, I could only stay up late analyzing data,
checking wallets, matching addresses, calculating win rates, and still might not keep up with the rhythm.
Now, it's different. I can directly view top traders in the community within the app,
their strategies, returns, and history all laid out, and I can follow with one click.

This is actually very important for ordinary traders.
Not everyone has the time, and not everyone wants to watch the market every day.
Sometimes, delegating execution to more stable traders is a rational choice.

Ultimately, what easyfun gives me is not just a "sensation of excitement,"
but a long-missed sense of certainty.
When placing an order, I know it will execute;
When copying trades, I know the logic is transparent;
Trading itself has finally returned to "judging whether it's right," rather than "whether it will lag."

And this is something I am increasingly valuing:
A good trading experience isn't about making you more aggressive, but about making you more calm.
