of course the demand would increase a lot if countries accepted bitcoins because people would buy as much as they can
bitcoin is definitely going to reach 700 dollars in like a month or so, i think that there will be soon a huge pump and dump that will push the price to the sky
$700 is just an inch away. No need for such a pump for that to make it to happen. A push from community can reached that price even without the help of big whales.
And no, people especially most here in the community tend to work to get bitcoin rather than to purchase it in a bitcoin exchange.
