SolarCoin needs as much coverage as possible, and viral marketing is one way to get it for sure. Investors in the project are great, but Im less convinced of the value of speculators/traders, aside for providing liquidity on exchanges, they deliver little value to the project.

So we need two strands of marketing, one for claimants, and one for the businesses that might invest. Investment in this context means more than buying some SLR, it means accepting SLR as a form of payment, and having other business partners consider doing the same.

We need to show businesses one primary thing; Using SLR will increase their profits

We can demonstrate this easily, lets assume SLR = $100. This makes the minimum TX fee to make a payment 0.0001SLR x 100 = $0.01, thats for any amount, anywhere in the world, in a maximum confirmation time (20 confirmations) of 30 minutes. Receiving funds is the same, except its totally free.
This is so much cheaper than any other form of payment and requires no bank instructions, bank costs, no merchant fees, no SWIFT/SEPA costs, and doesnt take 3-5 days to arrive.
Also becasue the block-chain is impossible to defraud in so many tradtitional ways, accounting costs are reduced, you look in the wallet, and have a fully audited amount, with every inflow and outflow confirmend by the entire SolarCoin global network.
