What's the advantage of buying Dolz tokens istead of buying credits ?
Perhaps a more relevant question would be "What's the advantage of selling Dolz tokens instead of selling credits ?"
I don't know the answer to that question either, but it is the more important of the two if you want to understand why it is being done.
Buy DOZL tokens, buy card which has a random chance rareity.
The more rare the more you can sell it for(main point of nft's is that you can sell them), then the buyer can sell it on for even more DOLZ and on and on and on. Until there is a crash and you lose all the value. :/
Because the cards are NFT's ownership needs to be tracked with a blockchain, DOLZ are linked to eth for the transaction. So a record of any sale will become part of the blockchain and the owner can be validated.
AFIK DOLZ isnt going to be specfic to this progran like the credits are they can be used elsewhere, vrparadise for one. I believe they are attempting to get the entire porn industry to use DOLZ tokens, as yet i havent seen any other companies planning to or have adopted them though.
At least thats what appears to be going on ...
