Bitcoin arbitrage plays a crucial role in maintaining price equilibrium across global cryptocurrency exchanges. By capitalizing on temporary price differences between platforms, arbitrageurs help align values and ensure fair market conditions for all users. This process not only stabilizes prices but also encourages healthy competition among exchanges, especially benefiting smaller or emerging platforms by increasing trading volume and liquidity.
For traders seeking to profit from these short-lived discrepancies, speed and efficiency are paramount. Enter BTC Trader, a specialized software developed by Eun-Joo Hansch Seoung and her husband Andreas to streamline the complex, time-sensitive process of cross-exchange arbitrage.
How BTC Trader Simplifies Bitcoin Arbitrage
Manually executing arbitrage trades across multiple exchanges is a tedious and error-prone task. It involves juggling browser tabs, copying wallet addresses, monitoring price feeds, and navigating different APIs—all under tight time constraints. BTC Trader eliminates much of this friction by integrating key exchange functions into a single, automated interface.
Originally built for the now-defunct TradeHill exchange between late 2011 and early 2012, the project was nearly abandoned when the exchange closed. However, the developers pivoted quickly, adapting the software to work with MtGox by reverse-engineering its API and reusing much of the original graphical user interface (GUI). The result? A powerful tool capable of automating most steps in an arbitrage workflow.
BTC Trader supports:
- MtGox API integration for selling Bitcoin and generating USD coupons
- BitInstant API for fast fund transfers between exchanges
- Real-time BitcoinCharts market overview
- Multi-currency balance tracking—offering a unified view often missing on major exchanges

A Real-World Arbitrage Example
To demonstrate BTC Trader’s capabilities, Eun-Joo shared a tutorial showing how a trader could execute a full arbitrage cycle in just 50 seconds:
- Sell 2 BTC on MtGox for USD
- Convert USD into an MtGox coupon code
- Generate a BitInstant quote with one click
- Transfer funds to BTC-e via BitInstant
- Confirm receipt using BitInstant’s API response
- Buy back BTC on BTC-e at a slightly lower effective price
With BTC Trader, steps 2 through 6 take approximately one minute, giving users a significant speed advantage over manual traders.
In this example, the user ends up with 2.0037 BTC—a small but meaningful gain. At scale, such micro-profits compound quickly. As Andreas notes: "With 100 BTC, you can gain about 1–2 BTC per day", provided the price delta exceeds $0.25 and execution is swift.
Core Features That Set BTC Trader Apart
While many traders rely on spreadsheets or basic scripts, BTC Trader offers several unique advantages:
- Unified dashboard: View balances across multiple currencies without switching platforms
- One-click operations: Automate coupon creation and BitInstant transfers
- Real-time market data: Monitor prices across exchanges directly within the app
- Risk reduction through speed: Minimize exposure during fund transfer windows
Despite its strengths, the software has limitations. Full integration with exchanges beyond MtGox—like BTC-e—is still incomplete, requiring users to manually complete the final trade step. According to the developers, expanding support will take considerable time and effort.
“The development of a BTC-e version may not take another year,” says Hansch, “but there is still a lot of work to do.”
Given the rapid evolution of cryptocurrency infrastructure, BTC Trader may never reach a "final" version—but it’s already functional enough to deliver real value.
Human vs. Bot Trading: Can Manual Arbitrage Still Win?
Many assume high-frequency trading bots dominate arbitrage opportunities. Yet Andreas argues that human intuition still holds an edge.
“Although many people are using trading bots, you can still make some profit because a human being will always be better in analytical abilities than a trading bot, which may be faster.”
He explains that less sophisticated bots often react predictably to price changes. By placing small, strategic sell orders, experienced traders can manipulate bot behavior—luring them into selling low before buying back at an advantageous rate.

Even with intelligent bots in play, market dynamics don’t always favor automation. Patience and timing allow human traders to capture gains without chasing every micro-move.
Trust and Adoption Challenges
One of the biggest hurdles for BTC Trader is user trust. The crypto community tends to favor open-source tools or self-built solutions, especially among technically proficient users who run Linux or audit code independently.
As Andreas admits:
“A proprietary software for trading on MtGox faces the difficulty that nobody will trust such kind of software.”
Convincing users to adopt closed-source software—even for free—is tough. Monetization seems even more uncertain. Yet the first download brought excitement, signaling potential interest.
“I don’t know if this user will try it. But I will know if he requests a license.”
Frequently Asked Questions (FAQ)
Q: Is BTC Trader still functional today?
A: While originally designed for MtGox and BitInstant—both largely obsolete—the underlying concept remains relevant. Modern versions would need updates for current exchanges and payment rails.
Q: Can BTC Trader be used for non-Bitcoin cryptocurrencies?
A: No, it was built specifically for Bitcoin arbitrage between USD-denominated exchanges.
Q: Does BTC Trader support automatic rebuying on destination exchanges?
A: Not fully. While most steps are automated, final purchases on non-integrated platforms like BTC-e require manual login.
Q: What are the main risks in Bitcoin arbitrage?
A: Price volatility during transfer windows, failed transactions, exchange downtime, and sudden market shifts can all turn potential profits into losses.
Q: How fast do I need to act to profit from arbitrage?
A: Ideally within seconds. Delays increase exposure to price changes. Tools like BTC Trader reduce execution time significantly.
Q: Is arbitrage still viable in today’s mature crypto markets?
A: Yes—though opportunities are smaller and shorter-lived. Geographic restrictions, regulatory differences, and liquidity gaps continue to create price disparities.
