It seems likely that BTC will continue its upward march... there's a finite supply coming face to face with increasing public awareness and interest... we're only at the very tip of anything that even vaguely resembles mass adoption. That's the upside.

The question mark for me is the technology... is Bitcoin going to start looking "old fashioned and slow" in comparison to some of the alt coins... even some of the alt coins that may not even have been invented yet? For example, my wife and I have a small art gallery, and we'd love to "help the cause" by accepting BTC as a form of payment... yet the functional implementation of that has issues... confirmation times... vs. taking the risk of these so-called "zero confirm" transactions now being touted.
