eBTC didnt even have white paper or anything. It was just another ERC20-clone token with nice name. Powtoken actually has white paper and some good ideas of been social media token. I will hold some atleast. I would not compare this to e-tokens.
WHY IS THERE ANY VALUE IF YOU ARE GIVING THE POW AWAY FREE?
A nice way to think about this is using early telephone networks as an example. When the first telephone networks were developed, the phone companies used to give new customers phones and connect them to the network for free. When there were no other users on the network, the early adopters didn't get any utility from the phone. It was just a silent object which sat on their hallway table. Distributing the phones was just a cost, with no immediate benefit for the phone company. However, as the network started to grow, and people started to ring each other, the phones' utility started to increase, making ownership of the phone highly attractive and creating a virtuous circle which lead to almost 100% ownership amongst the public.
The above can be applied directly to distribution of an electronic currency. Right at the beginning there is no real benefit in owning it, but as the network of owners grows, the utility grows massively, meaning that almost any transaction you currently do with traditional money could be done with POW 'lite' with zero fees and lightning speed and ease.
WHAT IS MY POWTOKEN.COM ACCOUNT FOR?
Your POWtoken.com account is for sending and receiving POW 'lite' to and from your friends. Initially we have integrated with Facebook, but will soon roll-out more social media platforms that can be used. All the free allocations of POW 'lite', are simoultaneously represented by a real ERC20 token on the blockchain. These real ERC20 POW tokens are held in a single ETH account on the Ethereum blockchain. Your individual holding of POW 'lite' is kept track of using a centralised database and is 'off-Blockchain'. The POWtoken.com site operates that database and gives you access to your POW 'lite' and the ability to transfer it to friends (currenctly restricted to your Facebook friends, but soon to be including your friends on all the major social media networks).
