When people start recommending the use of BitCoin as a alternative to your service you must surely know somethings up. BitCoin for all its faults (ease of use mostly) is a far safer alternative to PayPal (somhow), there are no risks of chargebacks and it is anonymous, also no one is turned away. Worth a look if you accepting donations or something, shame its not more widely used.
