I am new to bitcoin. I have some fundamental questions.
If bitcoin does not have any centralized entity controlling it, who provides the infrastructure for the trades to happen? Does this has something to do with mining?
Another issue comes to mind is, in case if full anonymity of bitcoin transactions, how can someone create trust between merchant and customer. For example, if I order something online using BTC and don't receive the goods, how can I make sure I will get justice in terms of refund etc.
