Are there dividends?
I don't think so mate no, for that I think the coins would have to be actual stocks and that is not what we've got here.
But you can profit from the success of this company. A higher price is always included in successes!
...a higher price comes from pumpers. End of story. Success of a coin or it's team has little effect on price, except when there's a huge community following and even then it's arguable.
