Risk & Limitations
Version 1.0.0 · last updated 18 August 2026
No real money is involved here
Every trade on this site is simulated. No real order is placed, no funds move, and there is no setting that changes that. This service holds no money and no exchange credentials.
That also means you cannot lose money here. The risk this page is about is different, and it's the one that actually matters: acting on what you learn here with real money elsewhere.
What this simulator still can't model
Koineti models exchange fees, slippage from real order-book depth, and minimum order sizes — which already puts it ahead of most paper trading. It still cannot model these, and each one flatters your results:
| Not modelled | Why it flatters the result |
|---|---|
| Market impact | Your simulated order never moves the price. A real order of any size does, and it moves against you. The bigger the position, the more this matters. |
| Queue position | A real limit order waits behind everyone who got there first, and often doesn't fill at all. Here it fills. |
| Partial fills | Real orders frequently fill part-way and leave you holding an awkward remainder. Simulated ones fill cleanly. |
| Outages and rejections | Exchanges go down, rate-limit you, and reject orders — reliably at the worst moment, because that's when everyone else is trading too. |
| Latency | The price you saw and the price you get are not the same price. In fast markets the gap is where the profit was. |
| Withdrawal and transfer time | Moving funds between venues takes minutes to days. Any strategy that assumes capital is instantly where it's needed is assuming something false. |
| What it feels like | This is the big one. You did not feel the drawdown. You were not tempted to close early, or to double down, at 3am with real savings on the line. A simulator measures a strategy; it cannot measure you. |
This list is here because a simulator that doesn't tell you its blind spots is how people conclude they have an edge they don't have.
Past results predict very little
A strategy that worked over some past window may have worked by chance. The more variations you test, the more likely it is that the best-looking one is a fluke rather than a finding — test enough combinations and something will look brilliant by coincidence alone.
Where Koineti sweeps parameters it shows the whole distribution rather than just the winner, for exactly this reason. An isolated spike surrounded by poor results is noise. A broad plateau might be something.
Why you'll see so many refused trades
Koineti declines far more trades than it takes — on the desktop build, roughly 769 declined for every one executed. That is not a malfunction. Order books are too thin to fill, apparent gaps vanish once slippage is priced in, and some spreads are so implausible they mean two exchanges list different assets under the same ticker.
The Reality Check panel shows what was refused and why. A track record built only from accepted trades, with the refusals hidden, is the single easiest way to make a strategy look better than it is.
Crypto specifically
- Prices are highly volatile and can fall very fast, including to zero.
- Many markets are thin, and a price on a screen is not a price you can necessarily trade at in size.
- Exchanges have failed, frozen withdrawals, and lost customer funds. Not a hypothetical.
- Regulatory treatment varies by country and changes.
- Tax treatment of gains varies and is your responsibility. Any tax figure this software estimates is a rough guide, not advice.
If you take this to real money
That's your decision and your risk, made elsewhere with a real broker or exchange. Some things worth having settled first:
- Never risk money you can't afford to lose entirely.
- A simulated result is a hypothesis, not evidence. Treat it as the beginning of the question.
- Costs compound. A strategy that's marginally profitable before fees is usually loss-making after them.
- Consider speaking to a licensed adviser in your own country. This site is not one.
