Alexa ranking does not affect the ups and downs of the number of users.
Of course thats true, because alexa ranking is not a site that promotes bitcoin forums but rather sites that analyze traffic from sites.
after all, ranking on alexa does not reflect this forum abandoned by users. because, as far as I know, Alexa ranking will increase if more members are using the Alexa addon in the browser he uses. this is makes Alexa ranking accuracy does not reflect how many users are actually active.
The level of accuracy that is not well indicated by the alexa ranking for the site bitcointalk.org is also not a reflect that the forum has lost many users, only the traffic measured by alexa ranking is a site search keyword or SEO. IMO
Of course, bitcoin forums have high search traffic from 2017 to 2018 because bitcoin is very popular among people because of the very high price jump of 20K usd. But after that, we can also monitor that there is a decrease in the number of active forum users during this time period due to several factors below:
- Merit system in January 2018
- Many ICOs end up scam
- Many bounty not worth it
- e.t.c
On the other hand, this forum is well known to the crypto community and does not need alexa to get revenue from advertising. just look at how much money this forum has from donors and banners. This is very enough to support the forum without having to alexa tracking to get advertisers.
Bitcoin and cryptocurrency have become popular assets and are already one decade old, we can find lots of news about it on social media and elsewhere. Increased adoption is also a determining factor that the forum is the right place to discuss a few of the problems in it without the need for promotion from other parties.
