Research before talking. Bitcoins are being spent more than ever: the transaction rate keeps increasing and is roughly doubling every 18 months https://blockchain.info/charts/n-transactions?timespan=all&d...

Preemptive reply to those who think speculators cause the tx rate to increase (often an invalid comment thrown out in HN): no they don't. Speculators typically leave the coins in an exchange wallet (they are not sufficiently technically savvy or motivated to run their own wallet). Buying/selling on an exchange does NOT create a transaction on the blockchain.
