just wanted to let you know that this coin is going to have a tough time of adoption. Your coin is already overrun with scripts that automatically bid higher than the person, and that also seem to have deals made with the mining pools as their lower fee transactions are also getting block priority. Tried high amounts five blocks in a row and every time a much lower fee got priority. And it is from one of the scripts that non stop subimits. You need to find a way to block the automated scripts or set it up so that no address can receive more than a certain number of coins an hour or day
Read the sections in the whitepaper on mining and clogging of the Ethereum network. It is expected that Ethereum miners will start cheating at some point if there is enough incentive to do so. Also note that not
all miners sort transactions by gas price. It is the default setting in geth, but miners are free to use their own sorting algorithms. Other things, like the sender address, time received, etc, could also play a role:
"It is expected that over time, only the most sophisticated minters, who are also willing to pay a high gas price, will compete for new SOV. An equilibrium should emerge between the cost of minting SOV and the price at which it trades on the market."
