nearly 300k transactions per day---are you sure hardly anyone is using it as a currency?
as technology improves and latency/bandwidth become provably less of a threat from increased block size, i don't think it'll be that big of an issue. this will eventually happen, just not on the timeline gavin andresen and mike hearn thought.
the question for me is, how difficult will it be to smoothly pull off a hard fork?
You betcha. I'll guess that's primarily money going to and from exchanges. We hardly hear a peep about actual expenditure these days and that's going to be become even rarer when people don't want to spend at all.
I don't think a hard fork will ever happen apart from the ones that deal with pure catastrophes. It's too late now. There are too many vultures circling too keen to throw a spanner in the works. One of the services the Bcashes has done us is to demonstrate what an utter shitshow it is when things are opened up to splintering.
