What it is
BuyCrypt is not an exchange. It is a venue where people learn to trade on live data from real exchanges without risking their own money, and where learning is turned into competition. A user enters a $5 tournament, trades the same interface they would on Binance or Bybit, and if they win, receives a $5,000 funded account with an 80/20 profit split.
Behind it sits the infrastructure of a genuine trading platform: one API over 22 exchange providers, a real-time quote stream over STOMP, position and liquidation maths, and three independent systems — the Java core, Django tournaments and the Flutter client — that must all answer “how much money do I have” identically.

What it does
01
Trade 22 exchanges from one interface
Spot and futures under a single order model on top of wildly different APIs, from Binance FAPI to MEXC. The user never sees whose engine is underneath.
02
Tournaments with a real prize pool
Two scoring modes — percentage price movement and net PnL. Ticketed entry, automatic winner settlement, prizes credited to balance.
03
Prop accounts on FTMO-style rules
8% target / 5% drawdown, 80/20 profit split, USDT payouts on-chain. The same rules as major prop firms, but entry starts at $5.
04
Demo mode on live quotes
A full simulation with a real order book, fees and liquidations. A mistake costs experience, not money.
05
Fraud and multi-account defence
A relationship graph across devices, withdrawal addresses and behaviour. Real collusion rings were caught exactly here.
06
An admin panel on live data
Streamlit console: users, tournaments, payouts, bot-excluded reports and manual interventions — in production, with no hand edits to the database.

Under the hood
- Java · Spring Boot — the core: orders, positions, liquidations, leaderboards, tournament scoring.
- Django — the tournament perimeter: creation, entry, rewards, organiser admin.
- Flutter — one codebase across iOS, Android and web, plus a separate terminal build with its own base-href.
- STOMP over WebSocket — real-time quote streaming and position updates.
- GitLab CI — the production branch deploys itself, no manual ssh in the loop.
- Backward compatibility is sacred: two-year-old app builds are still in the field and must not break.
