Oh well; I had a chance just 2-3 weeks ago (BTC was $194), but didn`t pull the trigger. Kinda kicking myself now, but... I don`t have the $ to be playing around with prices this high anyway. For me, the train has left the station (I may get on board with some of the other coins). In the meantime, this whole crypto-currency thing is fascinating and scary at the same time! I detest centralization and regulations, and I hope BTC can resist the dark forces out there that will more than likely corner the market by `owning` (via regulations/centralization) most of the limited # of BTCs (21 million, from what I`ve read). The times they are a changin`...
The dark forces would buy bitcoins only to create crashes to scare people away. Buying bitcoins and holding them makes no sense for them because it is just increasing the market capitalisation of the bitcoin system.
We could have said the train has left the station when it went from 10 cents to 1 USD. Or to 10 USD. Why today ?
The train will have left the station when there will be thousands of start-ups worldwide working on bitcoin related services, thousands of articles in the mainstream press all around the world, mass adoption in physical and virtual shops etc...
At that point one might say "the train has left".
Right now it's only warming up slightly.
