This definitely should go in another board, like service announcements or altcoin announcements.
If you leave only a link, many would not click on it for fear of it leading to a site containing malware.
If you post an article that is well written and informative along with the link, that could be a better format for people being interested and deciding to visit your website.
Also having 1 activity isn't something that would give people confidence.
If you'd take the time to analyse the post, e.g. quoting it to see if there is a hidden redirection, the links go to where they state. Cryptocoin (a trusted site) and their website, lest trustable, that advertised their coin.
It is completely safe.
I personally think all these gimmick coins have lost their novelty.
