I have the cash to buy 1 Bitcoin, But unless I can turn that into about 2 or 5 Bitcoins easily, Im not sure how worth it  that it would be buying that first one at $600. If it was 5 years ago and I could get the first bit coin for under $100, then waiting knowing it would go upto $700 then that would be profitable. I do have money set aside to invest also to help, But The problem is finding a method where I can make profit from bitcoin to begin with. If there was a way, I would buy that 1 BTC if i knew i could grow it, not just risk loosing it by bad trades or something...
