Changetip will begin to charge 1% on withdrawals from their digital wallet (which I don't think is unreasonable - credit cards routinely charge ~4% per transaction). No fee for actually making Changetip transactions. Fans could tip directly from their personal Bitcoin wallet to any Bitcoin address for free of course (truly removing all middle men). Still a far cry from the behemoth that is the recording industry leeches.
The future will be micropayments (tips) using digital currency like Bitcoin. ChangeTip has recently integrated with SoundCloud so that users can tip the artists they enjoy directly with Bitcoin. It is already in place for Youtube and other social media platforms. The middle man will be cut out completely.
