So I suppose currency
With investment potential for early adopters?

I think both in varying degrees.
If I had followed my instincts I would have purchased 10 bitcoins @$140 as an investment
When it reached $1200 I would have cashed in as payment towards a house in Italy I am currently buying.
But that was a couple of weeks ago when I saw the word bitcoin for the first time as I read the story about the Norwegian guy who found his Wallet information and realized he had amassed $850,000.
Since then I have read voraciously everything bitcoin and I intend to collect bitcoins as stock - because I truly believe in it as a future currency.
