The coin ecosystems currently is reminiscent of the wildcat banking era
Proponents of coins say this is a feature, not a bug.
Bitcoin is singled out because it is the oldest, most established, and if you naively believe that true value of all coins in circulation = spot price * number of coins, also the most valuable.
Sure other coins solve (or alleviate) some of the more glaring problems with bitcoin, yet other significant structural problems remain with the whole concept. One example: sometimes mediation is actually needed to resolve real disputes becasue we are afterall only human and bad actors are out there. The only way, by design, crypto coins do this is forking blockchains, a la The Dao and ETH/ETC split. Again proponents see this is a feature, not a bug.
Alot of wheel reinventing going on, done in ignorance of what has happened in the past WRT banking and finance. IT innovation in banking and finance is wild west stuff and an honest appraisal of things would be that noone knows what the fuck they are doing
