I don't believe this is the only reason, altcoin section is the busiest section of this whole forum, without it this forum would lose huge traffic and other beneficial things and eventually fade away. You guys certainly care about it and most of those who defend bitcoin and talk shit on other cryptos (even if they are good innovative coins) are benefiting from bitcoin and don't want to see any other crypto rise. I dare you guys to delete the alt section, you won't do it and to say people will spam the bitcoin section is simply exaggeration, most of them won't care and will go somewhere else which this forum wouldn't want.
