Yes I spend my bitcoins a lot on the online bitcoin market, because there is more to buy these days.
I also gamble a lot but this is with low amounts only so I will not lose a lot at the end.
What do you mean by online bitcoin market? Exchanges? Stores?
If you are pointing out to bitcoin store, you know many people here posting that there isn't much online bitcoin store that they know. Maybe listing your list here will able to help them.
I don't think he meant about exchanges etc.. as they are no where close to bitcoin market or a place to buy stuff.There are many online markets for bitcoin and you may read about them in many coindesk articles or have a look at the link below.
