Small online communities are thriving in quality but all the business models are gearing on communities becoming huge and exploitable with a content for the average. I.e small communities on reddit have high quality content when they are small and they start looking all the same as they grow, attracting trolls, propaganda and disguised advertising by power users.
-so we have content quality issues due to misalignment of incentives of consumers, creators and gatekeepers.
Here is the thing: Other countries will follow China's model and the current internet giants like Facebook and Google will lose their status of global giants. Even USA has strong anti-globalist movement and a president who is preaching it.
-so we have political landslide towards geographic compartmentalisation.
Bitcoin and other blockchain projects are reaction to the current direction of the internet. Transfer of value, distribution of value and guaranteeing identity are the pillars of the movement.
In my opinion, investing in bitcoin or altcoins with reasonable projects is a better long-term investment than investing in Facebook or Google.
