GainAlgo is an MIT-licensed crypto trading bot I've been building. The latest update lets it manage four exchanges from a single server and one dashboard:
| Exchange | Futures (USDT-M) | Spot |
|---|---|---|
| Binance | ✅ | ✅ |
| Bybit | ✅ | ✅ |
| Upbit | — | ✅ |
| Bithumb | — | ✅ |
That's 2 futures + 4 spot markets, all in one process.
Honesty first: it's not a money machine
On its own, the bot is roughly break-even. I think of it as tilling the field and standing guard 24/7 — the human still does the final harvest. Defaults are deliberately safe: every engine off, paper mode, single server. Live trading is an explicit, per-exchange opt-in.
If you came for "wake up to money piling up," this isn't that. It's a framework you tune — together.
Why one server?
Running a separate bot per exchange means juggling windows and duplicated infra. GainAlgo keeps them in one place but fully isolated:
Capital — one exchange's balance/positions never leak into another's sizing.
Records — trade journals, daily P&L, and gate stats are kept per-exchange.
Settings — entry/exit configs are tuned independently per exchange.
One screen, zero cross-contamination.
What shipping multi-exchange taught me
Before open-sourcing the latest work, I ran a multi-agent adversarial audit over the code and fixed what it surfaced:
- a paper-mode path that still queried the live account,
- missing order idempotency (a retry could double-fill),
- per-exchange record files that could overwrite each other.
Small bot, but I'd rather knock on the bridge before crossing it.
