yes there will be more people leaving.. but then again, people with free electricity and dorms etc... or rich will still profit! Once 1 block equals 25 btc.. it wil get scarce and the price will rise 50-100 usd in the future. that's what most are waiting for.
Most are waiting for $1,000+/btc. That's pretty much what it will take to even try and make this a viable currency. (price stability and a big enough market to actually make this work.)
The only thing that will make it a viable currency, is price stabilization. Nothing else. Value of the individual BTC is irrelevant to anyone but a Miner, so long that it's stabilized.
It would be nice for vendors to list in BTC and everyone know what that means, rather than listing in country of origin currency. Companies wouldn't need to adjust their prices nearly as much if it was all in BTC and BTC were stabilized to where people actually knew the value.
The only thing that's going to bring this is a stabilized market and something that doesn't drop 15% in just a week.
As it sits now, people don't know the value of BTC. I haven't checked in a couple hours. As of this post, I have no idea if it's back up to $8.15/BTC or back down to $7.15/BTC. It really could be either or in between. That's just a couple hours. Too much of a gamble for companies to set prices in BTC and too hard for your average person to keep up with.
