I agree with what you say, even though it's not entirely true. what we can do with coins fully in control is in our hands. but, we cannot control the market price of the coin itself. I mean, we can't raise and lower the price of every coin we have.
This is incredibly true. Though market changes are mainly determined by investors,,, it Is actually not entirely in our hands to determine what the morrow holds for a project.. There many other determining factors that can't be sidelined. I.e Team/Dev
investors will only invest if the project can get him interested so it is very true if you say if a team or dev plays an important role in developing a coin.
if the team has a good mission, the investor will invest heavily and that will make the value go up.
