did i just lose a .2btc transaction because the fee was set at .2btc?
Aww man, I'm so sorry reading that!! Things can be confusing in advanced settings, yeah... Better just stick to the regular send-feature! I once almost screwed up with those long Bitcoin addresses. Mixed up a few numbers or letters. It was already pretty late and I was out partying!
It is really not possible in practice to mess up typing a BTC address. Your wallet program would likely not allow it, as if you make a typo it would most likely show up as being an invalid address. What could happen, and does somewhat frequently happen is you could copy the incorrect address to send the funds to. This is a similar but different problem that the OP had, as the OP setup the TX so too big of a fee would be given to the miners.
I think the OP's situation is an important lesson of the importance of attention to detail when using BTC.
Yeah it's those little things that people who know Bitcoin and know how to use it don't get. The normal person on the street wants something to be easy and safe. If it was possible to pay more than you intended to pay with your Credit Card, people would freak out as well!
Sure, but BTC is more like cash. Irreversible.
if you drop a stack of 100$ notes when going out, they are gone.
If you pay someone too much and he is not cooperative, the money is gone.
I don't see the harm, but yes, everything could be more user friendly!
Yeah, sure. But that's exactly the thing. People want the security that Credit Cards offer them. I think they also still just have to learn to be more careful when it comes to Bitcoin. They shouldn't believe everyone and just send BTC to some address.
