For now I'd rather hold my bitcoin than spend it. Right now bitcoin value is high, so it's better not spend it often. Maybe in future, bitcoin might grower and the price rise up. So, I would feel regretful if I spend bitcoin.
You should also spend sometimes to help the circulation of bitcoin in market, but to earn good profits from it we need to hold majority of coins for future.
Hard decision for every person. They do have their choices but that is the very least we could do for its good circulation. Some should go to spending even if just the profits can have an impact.
