We're keen to use bitcoin and have been talking to various people about this for years. Would you believe bitcoin merchants are also susceptible to 'No adult content'?!!

I've been in the crypto-currency scene for a year now and I can say definitively that early adopter passion is giving way to healthy (and normal) market skepticism as the market becomes more aware of the technologies. It's atypical of the way any market evolves and how it evolves over time. Not sure why we keep expecting Bitcoin to go from zero use to global use in a matter of a few years...

The porn industry has, time and time again, used new technologies to overcome limitations of the medium by which they do business. I do think crypto-currencies play a part in that, especially when considering the opportunities presented by a global marketplace. Better you can sell to anyone anywhere with no fees, instead of being locked to a given region because of credit card number, or cost structure because of higher risk transactions.

My experience of accepting donations over 3 months on my site: a handful of donations via Paypal, zero donations with BTC.

UPD: doesn't matter though, I'd still implement BTC if I had to do it again. It didn't take much time and was a really interesting experiment. I do believe it's the future of Internet payments.

BTC is an investment pyramid scheme, but an entirely legit transaction technology. Just be sure to exchange the BTC back into normal money fairly quickly, as it's neither a secure nor stable store of value.
