Now, crypto is a currency people can choose to use. They don't have to. We need to build it as good as possible so that people who choose it, can. And those of us who want and have time and resources, focus on building good showcases, demonstrating that it works. Is rapid adoption that necessary? We need to be able to learn as we scale upwards. Right now, we're in the middle of the development after having learnt that "on-chain isn't the be-all end-all scaling solution". It was a fight getting here, and in the end the big-blockers went and created their own coin, which I think was good for all parties. Has it gone viral already, in a way?
Crypto prices have always been viral in various social and electronic media when prices have soared, and when that happens, it usually triggers the growth of new users who want to adopt crypto currencies.
IMO rapid adoption's very necessary, but it seems that it is difficult to be realized, given the absence of control from the authorities. "Quick adoption" is said to be necessary because this method is one of the ways that can stimulate market activity which at the moment seems lethargic.
