You know, we facepalm, but that's a big problem with BTC right there. Random Q. User has no idea about cryptography and what all those keys do and why you give out one and not the other and oh, I'd better give you both, I never know which one is which, all those numbers, haha, when I was young we didn't have so many numbers you know. numbers were shorter than, but it's the times I think everything get's more complex, oh so it worked thank you young man.
And there you have a recipe for disaster.
That's why I always suggest new users to services like blockchain.info. I've had newbies complaining to me that they've reformatted their PC and have their wallet password, but their coins are lost.
