I've seen in many posts that you are interested in something like a Bitcoin ATM, and there has even been someone who has built a Bitcoin ATM somewhere in the USA.
I believe that reprogramming an existing vending machine (specially condoms or parking meters for their size), or even taking an old motherboard or android phone, and attach a coin acceptor and a thermal printer is not exactly something revolutionary (technically speaking). But it hasn't been done yet (well, it has, but a big and mostly proof-of-concept project, diametrically different from the low cost, widely deployed EUR/USD/GBP2BTC machine everyone want).
So, my question is why. And thinking about the question I found that Bitcoin is not what people need. It will, when it succeedes (I'm optimistic about Bitcoin) be an extraordinary medium of storing wealth, something like gold today, with the additional advantages that everybody in this forum knows. But I don't think that people need to change their salary to Bitcoin (price fluctuations aside), exactly, again, as they don't need to buy gold with their salary. It's just not worth it. Bitcoin is not useful for buying bread. You can argue, of course, that if the baker accepted Bitcoin, people could use them to buy bread. But why would the baker accept Bitcoin, if he must pay his taxes in euros? It just adds more headache to his accountant.
Another reason I think that people will not rush into the ATM to buy BTC is the responsibility. Who would want to be considered the only responsible of protecting its own wealth? If you are stolen/threatened/forgetful that's it, game over. With a bank, despite all the inconveniences, hidden fees etc, if your credit card is stolen, you can chargeback. And the Bitcoin community does not support the idea of trusting a Bitcoin bank (which, given the past experience, I understand).
So, when I enthusiastically tell my friends about the wonders about Bitcoin, they ask me, skeptically, "how can I use them?" And in the answer I realize that they don't really need them, as well as they don't need gold coins.
People don't mind paying 2 euros more in an item of 60 euros because of the fees of Paypal, if they know that they can recover their money if something goes bad. Bitcoin has primitive escrow services, but are they below the Paypal fees? If yes, for how long, when the Bitcoin economy expands?
In conclusion, when I was looking for a catch phrase to write in the ATM describing why everybody needs Bitcoin, I realized that Bitcoins are useful for wealthy individuals and from a macroeconomic point of view, but not for the people that would casually buy them in an ATM.
I hope with this post to get contrary opinions about this fact, since I want to be convinced that a Bitcoin ATM would be useful, since I find the project of building one really, really cool :-)
A bitcoin ATM could improve access to bitcoins to those that aren't willing to spend the time to figure out how to gets bitcoins. If a bitcoin ATM were user friendly, even people that aren't computer savvy might use it to get some bitcoins just for the novelty of it or to just try it out. It would bring bitcoin to a segment of the population that might not otherwise take the time to learn about it.
