Testing
43+
------
44+
You can use the testing platform to test the APIs. The balances on the test sites are not real and do not represent any real value. The testing platforms work on Bitcoin TESTNET and you can deposit TESTNET coins to your account. The testing platforms are:
45+
46+
[BTCTurk Test] (https://btctrader-broker-btcturk.azurewebsites.net/)
47+
Important Our mobile applications will not work with the testing platforms. They can only be synced with our live platforms.
