Can you be more specific with your question? What do you wanna do? If you wanna setting the initial supply and total supply of coin and you should know what will be the purpose of your coin.

in my opinion if the supply of coin doesn't matter a lot as long as you have developed a useful product. If you are seeing CMC and some projects with billion supply can make its token worth a few dollar for each token while there was also another project with the same supply that each of its coin worth zero value.
