In my opinion it will be some bitcoin fork in the future that can act more like a currency. Effective currencies lead to true economic prosperity and in that masses of people see usefulness and ease of use is also necessary. Bitcoin is none of that. Bitcoin is a now corporate wallstreet rich mans' game. It's like walking up to the average person and trying to trade them gold for their dollars. They find more use in their dollars because more people accept them. Bitcoin feels like a venture capitalist and wallstreet fantasy come true and they own chunks of it probably almost all of it.

So i don't think the onboarding and adoption will come from bitcoin or 99% of altcoin projects. I think it will more than likely be a bitcoin fork with a good distribution system to the people where it was meant to be and not controlled by big insitutions and corporations .. a system not a business on the blockchain. An economic overall system that works for the people otherwise we can use the systems we already have in play.
