Storing $1 Million in your head while walking across a border is worth it for BTC to exist.
True, but the general public doesn't have 1m, nor need to take more than $9000 over boarders... but people have been treating bitcoin differently and way over valuing it, like the housing market of early 2000s. lol @ going all in on mining gear and paper wallets.
And also, this luxury won't be happening for long, the whole anonymity thing. I hope what seems like the inevitable won't be happening.
Stricter currency controls are likely in the near future. Legislation is being put into place - and is already in place in some countries - to legally confiscate private saving accounts. There will be another major crisis, and relatively soon. And more after that.
