This is indeed a very good question, what is our USP?

If I look at some of the other coins I see statements like:

• Bitcoin is an innovative payment network and a new kind of money.
• Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.
• IOTA enables companies to explore new business-2-business models by making every technological resource a potential service to be traded on an open market in real time, with no fees.
• Ripple - The world’s only enterprise blockchain solution for global payments
• Dash is Digital Cash You Can Spend Anywhere
• Monero is a secure, private, and untraceable cryptocurrency. It is open-source and accessible to all. With Monero, you are your own bank.
• NEM is the smart asset blockchain built for performance

Now if I compare the above with Gridcoin:

• Gridcoin is an open source cryptocurrency (Ticker: GRC) which securely rewards volunteer computing performed upon the BOINC platform in a decentralized manner on top of proof of stake.
• If you require a serious amount of distributed computing power for "FREE", you can easily create a BOINC project and the Gridcoin network can potentially reward your active userbase to help offset their electricity bills and improve userbase retention.

None of the other coins talk about the mining aspect, it can't be the goal of the coin from a value proposition perspective, it is 'just' a means to sustain the network security like the sha256 calculations in Bitcoin unless you specifically sell the capabilities like for example Golem.

So what is Gridcoin really offering coin buyers? What makes it attractive for people to buy this coin and not another coin? I believe this information should be on the Gridcoin.us website to attrack buyers.
