Nowadays, very few people waste their coins on gambling. In 2011 and 2012, there were so few options available for users to spend their coins. Most of them tried their luck on sites such as Satoshi-Dice, since Bitcoin was not being accepted anywhere else. But the situation has changed now. Currently there are a lot of options to spend your coins.
If that will change soon than there will be a lot of people that is getting a lot of profit and that would be nice.
Yeah and I think right now we only have that option of converting it to fiat and then spend, but we will see many physical shops that will accept bitcoin as a mode of payment.
in the future it will probably be a lot of physical stores that accept bitcoin as payment, but all depends on the development of bitcoin. if every year getting better and some countries many of which use bitcoin as a public service. it may happen.
