Speculative; Mass adoption will happen when mainstream addresses blockchain as technological innovation instead of cryptocurrency as a financial innovationr/CryptoCurrency
First wave of mass adoption I see happening in Asia (more specifically in China). They have shown that they are more open to this idea than Americans right now and willing to try on a bigger scale because they see the potential rewards. My strongest suspicion is that one of these supply chain coins will get traction and really start to make the value of crypto feel tangible on a business level, but at the same time they seem more ready for a change like this on a personal consumer level as well with what I've heard of Wechat.
I think America will be the second major market to wave, it feels like we are going to turn the tables on China in this tech in the sense that this time we are letting them research and test run a new large-scale technology and then coming after the leg work is done to reap the rewards. I am of the opinion that America will very quickly accept cryptocurrency and this is going to be triggered by the coverage of mainstream media change from being a financial topic to a technological topic. I've noticed that so much skepticism in the space is around the financial aspects and almost never about the blockchain technology in itself. taken from conversation on crypto panic via reddit
