Exactly and not only gambling people are spending huge amount of bitcoins even on trading sites and that is the best thing for the bitcoin economy as we need circulation of coins and cannot afford to keep our bitcoins idle in our wallet.
I will hold my coins for now, there is not enough good incentive for me to spend them. Sending them now, when we need to pay a half dollar transaction fee is a bit of waste IMO.
There is no exactly any incentive to use your coins when they might be worth 2x or 3x of current value in a year. Plus, you need to have access to your coins if/when Hard Fork happens.
Exactly,this is the point of spending the coins, we need to circulate it to the market. We need to help bitcoin to grow. You know what once we hold long the bitcoin the developers will be urge to produce many coins.
