I see many people creating new coins and many more investing in them... If you were to create your own coin, what would you do?

Tbh, most of the newly launched projects are greedy devs launching useless products just trying to make profit for themselves and eventually giving up on the project. I personally believe that for a coin to be successful, the product behind it also has to have some value to the users, such as improving an existing business model etc. So was wondering, what existing "problem" would you try to solve with your coin?

Would love to hear your thoughts...

On a side note, from an "investor" point of view, what are the most important things you look for in a new coin project?
