Will follow the development of your app as it seems interesting.
Thank you so much for your feedback.
You welcome, glad I can help you out. Though I have one more question which I forgot to mention above: Are you looking to implement the SegWit, might enable users to switch between SegWit and normal addresses, it is not important to add it right away but I do believe it is the feature that is going to be used more and thus it would be really nice to see it in the app.
Hi. We just released first version so a lot of functions are still not implemented.
"Exchange" - In the nearest time we'll integrate Ethereum, so users can exchange BTC for ETH and so on.
We are looking third party APIs to implement this feature. Right now there are 2: ShapeShift and Changelly.
Yeah shapeshift and changelly are standard ways that many wallets opt for their built in exchanges which is good to see here as well.
