I see 2 options:

Difficulty increases ... Miners earn less btc and bitcoins take longer to generate.. less new btc on the market.

Market value continues to drop .. mining no longer becomes profitable.. less new btc on the marker

What we really need is a secure and easy payment service to rival paypal.

Average joe and jill need to be able to use bitcoins not just techies.

right now supply outweighs demand.
