This is currently an experiment, but if it works, there will be more available:Cam4.com
is one of the World's largest free cam websites with 1000s of amateur performers.
Cam4 also has tokens which can be used for "tipping" cam performers during their shows.
I have an inventory of tokens that I am selling in exchange for Bitcoins.
The BTC to Cam4 token (C4T) exchange rate will fluctuate based on the value of the Bitcoin, but you will pay approximately 1.2 cents (USD) per C4T at the time of purchase. Check this against the cost of buying them through the site and you will see that this is a good discount.
There are a couple of steps involved with getting your discounted tokens, but you do not need a credit card and you will get them for less than they cost at the site.
If the demand is there, I will expand this offering.
PM me if you are interested or you can post here if you have any questions.
