We implemented Bitcoins half a year ago, simply because integration was easy (with coinsnap) and we wanted to offer customers another anonymous payment method. All shops at shopmaker.com now have this payment option.
However, revenues via Bitcoin are negligible, but with a slow upward trend. Very slow

If it picks up, great. If not, we did no invest much (time).
Our most important anonymous payment method still is paysafecard. With solid sales. Unfortunately it is still mainly available in Europe.
But obviously most customers do not care about anonymity. Credit cards are dominant.
