What does it take to influence the market of an altcoin? Buying a big amount of the total circulating supply from 1 exchange wouldn't work right? Or does the price go up while buying that big amount? To get that to happen the exchanges would have to look at eachothers prices right?
when you think that "the market" exists, then you wont be able to influence
second problem is what do you mean with "value",
people today mostly cosider value as liquidity in the lead currency of US dollars,
the market consists of very diverse interest groups,
if you want your coin to grow in US dollar liquidity u need to attract and give reasons to those that hold many us dollar,
in that case you have more or less 2 different interest groups
1. Salary dependent employees, these want to have more US dollars
2. US capitalists, these seek to improve the power and value of the US dollar and protect themselves from Cryptoeconomics , these basically think the same like the bitcoin capitalists.
