I think I'm using bitcoins less but on the flipside I've been earning more bitcoins so it balances out I reckon.
If so, what can we do to help increase it?
I think the answer to this is pretty obvious: use it more. Though according to this thread
https://bitcointalk.org/index.php?topic=1078996.0 there is a record 152,800 Bitcoin transactions on May 28 following constant growth all year, so I think bitcoin is still growing just at a sklow rate that we're not really noticing.
