December 2013. I discovered Bitcoin and ordered a graphics card to mine altcoins. While waiting for that delivery, I created a simple program in a few afternoons that would do arbitrage on Cryptsy about 10 days, I turned 0.1 LTC in 1 BTC. I sold my miner soon after.

Together with a friend of mine we improved that simple program. Currently we have over 40 BTC, I do not think it is possible anymore to turn 0.1 LTC into a few bitcoin in today's market. But our profits the last 6 months were enough to offset the decline in bitcoin price from $600 to $220, so it is certainly still profitable.

The program has now grown into a trading bot that we want to start selling to the public. The trading bot is a command line application with a configuration file that can be easily created and modified with our GUI. The bot and GUI are separate programs and can be run on different systems. For example run the bot on Linux and use the GUI on Windows.

We are currently running a pilot with a handful of users. The software obviously works, but the user experience is not always ideal. We are mainly focusing on improving that. We expect to go live in a few weeks.

Features
What we do not do:
 - EMA crossover.
 - StochRSI.
 - Fancy GUI's with 20 sliders and checkboxes that need constant babysitting.
 - Send your api keys to our servers.
 What we do:
 - Fully custom trading strategies that have been verified to work in the field. Not just in backtesting.
 - Extremely low maintenance.
 - Easy to configure. Simple GUI with a few options.
 - Track profits via external (open source) application that produces pretty graphs and mail reports.
 - No-nonsense.

Supported exchanges
BTCChina, BTCE, Bter, CEX.IO, Hitbtc, ItBit, Kraken

On these exchanges we support almost all combinations of currencies and cryptocurrencies (only on CEX we do not).

Supported platforms
 - Windows
 - Linux (Debian, Ubuntu, CentOS upon request)
 - OS X support not planned
 - Raspberry Pi upon request

The GUI will probably be open sourced soon, so users with unsupported platforms can compile their own version.

Target audience
The tool is suited for you:
 - if you have too many bitcoins or other cryptocurrencies on the shelf.
 - if you are into cryptocurrencies for the long run.
 - if you understand the risks of cryptocurrencies and exchanges.

I expected that question. To back up our claims we have:
Since 22 dec 2013 daily balance data from all exchanges in csv format.
Since feb 2013, half-hourly balance data from all exchanges in csv format.

As we mentioned, we have an open source project that collect this data and creates nice plots automatically. It takes a bit more time to format those plots in a way that the community can't misunderstand them.

Additionally, i am prepared to give a few members of the community access to our accounts so they can download our trading, deposit and withdraw history. The only problem with this is that most of our early profit comes from bter, an exchange which does not seem to keep that data for more than 24 hours.

1. Testimonials from new accounts will not be considered valid. At all. Do not bother.
2. Get a couple TRUSTED community members and have them reviewing your code, or make it full open source.
3. Post that hypothetical performance publicly.

Otherwise GTFO, seriously.

Before you say anything about the novelty factor of my account, I am not here trying to get profit or convincing anyone.

GL.
