As the name implies, this forum is dedicated to talking about alt coins and initial coin offerings but also has spaces dedicated to the big names like Bitcoin. A sampling of the alt coins on discussion here include Dash, Monero, and Cardano, among others. There are also sections of the forum dedicated to mining, avoiding scams, blockchain tech in general, and discussions on taxation.
The local posts section will be of the most interest to non-English speakers and offers support for Arabic, Indonesian, Bengali, Spanish, Chinese, German, Greek, Japanese, and French as just a few of the languages offering localized forums.
One thing worth mentioning about this forum is that it also has its own token.
