i don't use bitcoin at all. I try to keep it and wait for its price to go up and then i sell it to get some profit. That is because in my country the government does not accept bitcoin as a currency and it is still illegal to use bitcoin right now to buy food, etc. So my only choice is to hold them in my wallet
I don't think that bitcoin is illegal in most of the countries, even if its not getting support from Government that doesn't makes it illegal, if you can easily convert it to your local currency then everything is fine.
