I wonder how much time and money the development of such a project would require. It looks like there's been quite a bit of time and effort invested in this already.

I hope you'll succeed in developing this, it could be a very good thing for people like me who accidentally got into cryptocurrencies through questions from customers but have been hesitant to take many risks - the economy is not such that small businesses can afford to take many risks. I'm glad practical solutions to many of our concerns are under way. I find the idea of cryptocurrencies fascinating and certainly worth looking into. Projects like these could help convince other small, hesitant business owners to be more open to the idea. To be honest, I put off looking into it for quite a while because I didn't know what it was and found it all a little daunting (and making enough money to get by is tricky enough and taking up a lot of time as it is for most of us).  

I think what would greatly help many of us (speaking as a rather ignorant business owner) is user-friendly projects that minimize potential risks and this one looks promising.
