If after 9 years you still don't know what bitcoins are for, you're doing it wrong. Enough said.
Could you please explain then? I personally am curious as to what makes BTC so attractive
outside of investment opportunities. If you think it actually makes you harder to track than other forms of tender you're mistaken. Cash is pretty anonymous, BTC leaves a trail no matter how hard you try to fight it. Can that trail be obfuscated? Yea sure, but a motivated-enough adversary could absolutely figure out who you are. IMO the only use of BTC is as an investment which is a shame because its a cool idea.
