I have actually very concrete ideas about what sort of hardware to provide - but what I don't want to do is fall into the trap of "I think we should use x" just so people can then say "ooh no I don't like x I like y". If you notice, I am deliberately light on technical detail - not due to the fact that I haven't got an outlined planned but just due to the fact that I don't want to go in a direction that the majority of contributors don't agree with (or a least a vocal minority). If I say "the expense to the merchant is 0.5%", someone will say "oh that will never break even". If I say 2%, someone else will say "that's far too much". If I say "let's provide them with budget android devices", someone will say "OMG no-one is going to trust 5000 BTC on one of those". If I say "let's supply merchants with brand new ipads", someone else will say "but they'll just 'lose' them".
Ok - here's a challenge for you. Instead of rubbishing what I am trying to do (and include personal statements about "I'm surprised no-one is throwing money at me" - based on what did I say again ?) - how about you list a series of questions which I will answer, and if you think there is a better answer, then after a constructive discussion, we'll adopt your answer. How does that sound ? But if your reply is just "don't do it - it'll never work" then my retort to you is "People who say it cannot be done should not interrupt those who are doing it.”. I'm more than happy to answer - or try to answer - any questions you have. But please stop saying "it's not going to work stop trying".
You seem to have a misapprehension over where the onus lies.
I (and others like me) aren't the ones seeking reasons to invest in your project. You're the one trying to raise funds - so the onus is on YOU to convince others that your idea will work.
The fundamental questions you need to answer in my opinion are:
1. What is it you'll be offering that Bitpay doesn't? Bitpay allows merchants to accept BTC payments and receive fiat equal to the price they want (less a fee). They don't need BTC wallets at all. They don't need to know or care what the exchange-rate is.
2. What can you show to demonstrate that you've done the ground-work and have the competence (either as an individual or within your team) to deliver on your project?
Where I have ffurther concerns is that I don't believe the funds you're asking for are sufficient to do what you plan to do. Are you planning to do it all yourself without any pay for your work? Staff travelling around to merchants and demonstrating the hardware/software costs money. As does staff cold-calling (or whatever you plan to do) to identify merchants to demonstrate your product to in the first place. I seriously believe the funds you're asking for are an order of magnitude below what you'd need to make any sort of decent attempt to deliver - but as there's no attempt at any sort of cost projections in your fund-raising request I obviously can't point to the specific things you haven't covered.
If you want funds then you need to convince people that you can deliver, that the funds you're asking for are sufficient to deliver and that IF you deliver there's a market for the product. I'm not seeing any of that - the need you appear to have identified is one that's already got a solution.
I should note in passing that you appear to be in the UK - so potentially you DO have a market there that (as far as I know) BitPay aren't in any way focussing on. But have you done ANY market research showing that there's actually demand if you deliver?
Contrary to what you seem to think, I don't have any interest in dissuading you from continuing - it makes zero difference to me. I'm just pointing out the reasons why, as it stands, your proposal is of no interest to me. If other people are PMing you en masse and donating by the bucket-load then clearly I'm wrong. If they aren't then maybe the reasons I'm expressing are actually similar to those of plenty of other people.
YOU need to convince US that you have a good idea - we don't need to convince you of anything.
