and which public chain do you think is going to do the most volume?
bitcoin? ethereum? thingchain? a less secure private chain?
At this time it is impossible to predict which chain will get the most volume. It might require that the technology is implemented by stealth and people don't even know they are usin ga blockchain in order for it to overcome the terrible Bitcoin marketing.
To anarchists it would seem like Bitcoin being associated with Silk Road, and now the ISIS terrorist, is good marketing. It's actually terrible marketing.
While it might seem that a lot of Americans at least give lip service to being against the War on Drugs, or supporting the decisions of Edward Snowden, the actual behaviors and shopping histories don't necessary reflect that. The same with privacy where a lot of American citizens may say they believe in strong privacy rights, but the behavior doesn't reflect this.
I would say it's not possible to predict how the blockchain will go mainstream or whether or not it will be Bitcoin. It's 50/50 whether or not it will be Bitcoin. I think politics are bad for marketing because a lot of people will never use a currency associated with something they don't believe in. A lot of people will never use a technology associated with something or someone they don't like.
Political neutrality is better for marketing to the mainstream while for the hardcore activists political marketing works best. Bitcoin is being politically marketed which is why adoption isn't increasing very fast. The blockchain itself doesn't need a brand at all, and no one has to know about Satoshi Nakamoto, or politics, to simply use blockchain technology. In fact people would not have to know they are using it at all, it would just be the new way to trade stocks.
