We may increase the block reward bonus to 5 tomorrow to attract some whales. Network hashrate is definitely a problem. Those who support PXL we could definitely use your help mining! We are considering all options right now and keeping a sharp eye on the network hashrate.
You need to advertise the coin more, especially on community hubs like reddit, facebook etc.
We do plan to advertise but we want to get on an exchange first. We want people to be able to easily purchase coins through an exchange once they hear about the site and get excited about it. There is no point to begin our big push yet because if a company wants to advertise their only option is to go to a forum thread and try to negotiate a deal with someone who may try to scam them. We don't want that because if advertisers have a bad experience it will give us a bad reputation in the long run. So once we are on an exchange we will definitely begin our big "marketing push". This coin is all about advertisers - they are the ones that will essentially fuel the growth of the site and the coin. Advertisers having convenient and affordable access to PXL is paramount to our success.
