Either way, I lost another two days and a small amount of Bitcoin for this ultimately ineffective service. The major decentralised exchanges operate within Australia, with the exception of BitQuick. So the entire weekend was wasted by LocalBitcoins. This means that if the seller runs away with your money and does not release your Bitcoins, LocalBitcoins. Comment below. Right now, it looks like LocalBitcoins. Coinbase and Circle are both prominent and feature-rich exchanges which allow you to sell Bitcoins for USD.
