I'm not in favor of another bar, ticker, or anything. There are already too many things that distract me. Now there is also a voting bar next to the 365 news bar, animated ads at the top of the page, additional ads within the topic, a post with rules... The forum is turning into an ad platform.
As for the purpose itself, I did not get the impression that it is necessary, but if the need is recognized based on the previous requests, I can understand.
It certainly looks better than the news ticker.
Buying or not, anyway, most things in crypto come down to the same thing, paying attention and artificially creating more interest in a token or service... It just fits the current trend.
