Can anyone give me a likely scenario that would send the price up, or at least stabilize it so that XBT could work as a currency?

Remittance doesn´t make sense because you are likely to loose less by using Western Union or bank transfer.

Paypal using XBT sent the price down!?!
Argentina and Ukraine using XBT sent the price down!?!
Just about every piece of good news in 2014 has sent the price down. What can change that?
