Some general thoughts on new coins.

No 500 billion supply for a start. Those coins will spend their entire life on the lower tier exchanges (I don't know how ripple does it). No coin burns etc either. Keep it simple let the market dictate value based on a sensible supply for your project. Think about it there are only 7 billion humans on the planet and 90% will never own your coin. So 500 billion is too much. People need to think in sensible numbers. If you can keep it at a sensible number in peoples heads they will use the coin more.

Make sure no single person controls too much of the coin apart from you (do not give half the supply to favourite Uncle Bob who then falls out with you etc). You will regret it. Don't pay your developers in coin; pay them in USD. You let them get control they will get greedy and ruin your project with pump and dumps. Been done.

Avoid running forums and chat boards - just do the coin. It looks bad. If people want to do that let them but don't you do it. You can blog but not run a social site for people to cause mischief directed at the coin and you directly on your own platforms.

Your coin has to do something; can't be trying to be BitCoin which is the only value store coin worth anything. It won't fly. Take blockchain and use it to achieve a goal. Not a techie goal a goal normal people need to get done. What are you interested in, can blockchain help make it better? Example there is no loyalty coin I know of were retailers can make use of the blockchain to track and redeem loyalty points (imagine all that heavy infrastructure gone replaced with simple blockchain). Make it cool, make it for the young first not the old and it will catch fire. Blockchain is for the young not the old (sorry old people).

Throw money at the best web site you can get. Pay for high end graphics. It needs to be amazing before you launch the coin. Grab images of the team show the bios. Investors always need to see this as it is like paying off your credit card to credit agencies - it shows you care and are invested yourself.

I don't think minning is of much interest to the average coin user so I would not bother with ASIC resistant minning (but evidently don't make it easy to mine all the coins in one go). I would follow BitCoins example here. Bigger rewards to a small group will make matters easier. There are plenty hobby coins and mostly they have low values forever. I would avoid trying to pay people to "use" the network or "run" the network outside of mining. Don't ask the average punter about your tech or any of this stuff - just do it. They want to see what can be achieved not how it is achieved.

Wish you all the best with your coin! Hope you achieve something and don't just make money as reputation lasts forever money doesn't.
