I have some question hope you guys can answer.. english is not my first language and I dont know much about bitcoin.
1- Can I rely only on bitcoin and not have a bank account specially that I live in a country where bitcoin is unknown?
2- If not.. where can bitcoin be used?
3- If the world Economy collapses, will the value of my bitcoin go down?
4- Does Bitcoin use Usury loans and take interest?
-yes, if you want to convert them to fiat you need to register on an exchange
-some site let you pay directly in bitcoin, or you can use all4btc which buy everything for you and you pay in bitcoin
-it should rise in theory, because everyone will buy more btc, they will see it as a "safe heaven"
-i don't think so, anyway it should work like fiat in this case
