I think that right now we should start counting webcam sites that don't offer bitcoin payments.
For certain (just checked) that two of the biggest like lj and chaturbate are accepting
BTC , and lj even litecoin.
For them is far better as it easier for customers to pay and that way is easier to spend day and night.
You might not have funds on your cc or in your bank but your coins are always in reach and ready to be spent.
For sites that are doing recurring 30 days membership
BTC is not that attractive.
others got scammed instead of live they play the recorded video to earn token. But the scareist of all is they payed token to kill someone will recorded on camera.
I'm pretty sure this would have hit the news if it had actually hapnned.
