Adding other btc-api suported coins.

[Toni-d-e-v]

Could you help me or add ability to not use btc node but litecoin or dash so you can add lighter chains to the exchange.

We are open source biggest balkan cryptocurrency community crypto.ba We have our coin RXC based on dash x11 and we want to add it to your code to add to our exchange, we are nonprofit community.

Thanks
