Barry Silbert is more optimistic than most about the future of Bitcoin. Here's my favourite prediction of Silbert's:

1. Bitcoin will enable Facebook to provide remittance, banking and person-to-person money transfer services to its users.
Rumors that Facebook wants in on the e-payments game at home and overseas are making the rounds, but the billion-member social media mammoth has yet to confirm a single one of them.

Silbert told us that because of Bitcoin and other cyber currencies, Facebook will become a go-to platform for moving money from person-to-person, domestically and across borders. He also thinks it will also provide a host of basic banking services utilizing the Bitcoin currency and protocol.

That would be huge for Bitcoin's growth.
