That said, it seems to be a split between people who really, truely don't care, and people who go "hell yes! Fuck the fed! I need to get into this". Not an even split, but a split. Most people don't care, or worry about "how do you get the money back out".
There are also people who think it's a cool idea, but probably a scam.
I haven't told many people, so these statements of mine don't come from much of a sample set.
There is also a fair share who like it for the ease of transferring and speed / safety. Then a good portion like it for everything involved with it.
