TREX is a "pay as you use" application. Payments for the software are made using your digital currency wallets stored on Bittrex. To enable this you will need to provide the application with your Bittrex withdraw API keys. TREX will prompt you for a password to encrypt your API keys and store them in your user folder (for networked computers note that this might not be a local drive.) Your encrypted keys are kept by you and only your password can decrypt them for the application to use. A software payment is required under two circumstances:

  • While in “Automatic Trading" mode, the payment buffer (displayed) has filled to over 100%. Please note: if you close TREX before it hits 100% you can avoid making a payment, also payments can be automatic when the buffer is over 100% if two factor authentication is enabled on Bittrex, otherwise you will need to authorise every payment through Bittrex to keep the application from automatically shutting down. The payment buffer fills with the repayment activities of the loan/repaymanet mechanism (and on the loan side for GroupCoin-BTC Safe price spikes.) Even if the buffer hits 100% and you make a payment, you keep the difference between the total profit on repayments (which can be much higher than the minimum stated below) and the fixed rate TREX payment share:

    Pair Type Minimum Total Profit TREX Payment Share
    GroupCoin-GroupCoin 7% 0.5%
    TUSD-GroupCoin 5% 0.25%
    BTC-GroupCoin 5% 0.125% (+ 0.125% on BTC Safe price spike)
    BTC-TUSD 3% 0.125%

    Percentages are the proportion of the loan size you are using for the loan repayment mechanism. For example a $10 loan size would be a minimum of 70 cents profit for GroupCoin-GroupCoin loans with the buffer filling by 5 cents and you keeping the other 65 cents (or more.)

  • While not in “Automatic Trading" mode, and you have not made a payment to the for longer than 7 days; a payment is required to enable the functionality of the “Redistribute” software tool (the user will be prompted by TREX to authorise payment and also the user must authorise using email if two factor authentication is not enabled on Bittrex.)

On Bittrex there is a security mechanism used known as 2FA or Two Factor Authentication. If you disable it then all payments need to be authorised by you by email. You can initially disable 2FA so that you can authorise every payment to the The whole process works in the same way with 2FA enabled, except you don't need to authorise payments by email ("Automatic Trading" payments will be fully automatic once the payment buffer exceeds 100%. TREX will prompt you when you are not using "Automatic Trading" before making any required payments; if you haven't made one for over 7 days). We aim to take small regular payments as the software gets used. The month to month (1st to 1st) payment size dollar value change will never exceed 25% on the previous month's USD, value as set out in the Terms of Service. You can review your payments through "Wallets" on Bittrex or you can login to this site to review your payment history (and current bot performance if you want to check how an "Automatic Trading" run is performing while you're not at home.) If at any time you wish to stop making payments, then simply stop using the software.

Your Bittrex data (API Keys and Secrets) is stored locally in an encrypted format: These values are never sent to

Some other trading platforms will charge you on your profits so as they go up so do your fees. At we charge you as you use the software, so if and when you do make large profits - you can keep them.

Unfortunately there is no free version, but compared to the current competition: for small, medium and large scale investors is amazingly good value and we intend to keep it that way!

The payment mechanism might seem un-necessarily complicated, but it actually does something very useful: It allows users with very modest investments to use the system at a reasonable price, while ensuring the software producers get a fair share of huge profits made by the very rich. Increasing the value of funds used while automatically trading will increase the frequency of software payments.

You can expect to make good profits; most of the time. Using a $500 portfolio spread over 20 different digital currencies, a $5 dollar profit per day does not sound like much, but that’s 1% IN A SINGLE DAY. Many bank accounts pay less interest in a whole year. And TREX can do this while prices are falling, rescuing money that you would have otherwise lost. Having a bigger valued portfolio amount with more currencies opens the door to bigger profits (having more coins available for multiple loans in each currency and also more of the currencies enables TREX to monitor more markets, and also frees it up to react to price fluctuations by performing more loans.) Over $80 per day profit can be achieved with as little as $5,000 in digital currency on Bittrex: That’s more than you would make if you were mining digital currency with $5,000 worth of hardware, consuming enough electricity to keep a kettle boiling constantly (very costly!) For larger investors, TREX has been designed with you in mind, but is a new company and does not have access to hundreds of thousands of dollars to test the application against, so we don’t have data at this stage to inform you on. During development TREX never lost significant amounts of money, due to error or trial and error testing, this is a testament to the stability of the Bittrex platform. If you have over $100,000 in digital currency and would like to go somewhere no one has gone before: TREX is ready, and would love to have the data the run will generate. (There will be occasions when the system actually loses you money; there is no way to completely eliminate risk.)

TREX enables users to monitor its performance by showing the difference between 1. What your portfolio would be worth if TREX hadn't done anything and 2. What your portfolio is worth now after fees have been deducted. This "Profit/Loss" calculated value can be viewed anywhere by you by logging into this site while the application is left running at home. Note that if you manually execute trades or transfers on Bittrex while TREX is running in "automatic trading" mode this calculation becomes inaccurate. Larger investors will incur more fees because the frequency of payments will increase while the payment size remains the same (payment size can always be viewed on the page footer below,) rate of return does not change for larger investors: The percentages for filling the buffer remains the same, as do the weekly payments for manual batch trading, however we expect larger investors to configure the application to perform more and larger "loans" in automatic mode meaning the payment buffer (displayed to the user) fills quicker and the same size fee is paid to at a higher frequency than it would be for smaller investors. All fees paid to can be tracked using either this website or the Wallets page on Bittrex
