Sales is today but marketing seems pretty quiet
Maybe GpuCoin should consider refocusing their target market from gpu miner to regular people since it looks like there's not enough demand.
In my opinion easy acquiring of gpucoin by consumer is the most important part to focus on whether your target is gpu miners or other people. Even though I dabble in crypto myself I just want to click a big button that says Get GpuCoin and pick 5$, 10$ or 50$ etc worth of gpucoin and off to the online store. GpuCoin should also offer to buy whatever amount of gpucoin from miners at average market price and let consumers who's not into mining or trading get them at the site at above average market price. That should be the primary way for them in getting rid of their pools of gpucoins instead of solely dumping on exchanges.
Also in the future I suggest sponsoring gpus to one of those gamers that streams. They are celebrity in the kids world with thousands of followers and marketing should target people with that kind of connections
I don't know of GpuCoin LLC plans cause they're not sharing but the business feels like it could be managed better so can't blame people for worrying.
