Bitcoin is well known around the world, strong and alive, but the use of it is far from being a reality.
Anyway, step after step the future arrives: so, did you think about a single thing that will let you say: ok it's done, bitcoin is unstoppable, for all, the common people too!
For me it's a simple thing, a legal sport betting site that 1) allows you to deposit and withdraw bitcoins and 2) works as a withholding agent, so people have not to worry about taxes.
Probably this is not important in every country, but when it will happen in mine I will think bitcoin has definitely won.
