Sales platforms for products such as ebooks and programs, where users can offer their products downloadable online with a possibility of payment via PayPal, have been around for more than 10 years. What seems to be differentiating DecentGo is the use of BlockChain for its operations, but it would have to see in detail as they say that they use BlockChain to operate, because I have the impression that companies start to appear to ensure that BlockChain is used when really do not use it, and they only do that to attract customers, since the criptomonedas and everything related to BlockChain are in fashion.
