Echo chamber - an environment in which a person encounters only beliefs or opinions that coincide with their own, so that their existing views are reinforced and alternative ideas are not considered.
For a long time now (and particularly since the big crash after $20k), I've noticed how unhealthy a lot our cryptocommunities are. Bitcointalk in this regard is not the worst offender, but recently someone replied to a post of mine saying how a lot of their beliefs in cryptocurrency were just parroting without any real thought or research.
This phenomenon is a hundred times worse on individual coin/token communities. One observation I have made is the more obscure and unlikely to succeed a coin is (provided it is not a scam), the more fanatically users believe in its success. Whether this is self-deceptive rationalisation after seeing the price of their coin plummet or plain delusion I don't know.
This is financial bias at work. People are hyping up their holdings -- partly to convince others to buy, and partly to convince themselves to keep holding through huge losses.
Communal reinforcement in this way is incredibly dangerous, and could prevent us from seeing/preventing future problems with cryptocurrency. My question to you is what can be done about this increased tribalism? On a platform such as Facebook it is as simple as changing what material a user is exposed to. What can be the solution to such a big problem?
Cryptocurrency is novel in the respect that users are inherently
investors. I don't think there's an easy solution to this problem. You can see similar behavior in the Yahoo Finance boards with people shilling the penny stocks they own.
