Advertising is more of a balance with liquidity providing and additional exchanges.
The best advertising is performance.
QUSD is a new project and I am sure that developers are planning to start advertising soon.
I think that a very strong marketing support is needed for the success of the project. You need a lot of advertising, paid articles in magazines and online publications, a review of bloggers and analysts and much more. Then the project will be successful and famous.
I have often seen situations where a lot of money is spent on advertising, but the results are few, so advertising needs effective.
