Too Long; Didn't Read
Bitcoin can be adopted fully by the mainstream but I doubt if it will ever fit in. A lot will have to be changed for it to fit. Bitcoin is way too decentralized and this makes it a problem for mainstream finance. A coin that controls itself, rules itself, and determines its own fate doesn't sit well with any government. Mainstream finance will always see bitcoin as a threat rather than a component. Bitcoin has value because it upholds very well when it comes to the 6 qualities of a currency: scarcity, divisibility, utility, transportability, and counterfeit ability.
