It only took 66 years between the first powered human flight to landing humans on the moon. It's not unreasonable to think we'll have a colony on Mars in the next 120 years.
I believe we will likely have a colony on mars, but its unlikely to be a fully functional place to live. It'll likely be experts placed there, so that they can effectively build infrastructure, and colonize the planet. Its unlikely to have a currency, and will likely be employees of various different space companies. However, the reply did imply that there would be multiple planets using Bitcoin, and at the moment its only really Mars that we have any hope for, and we don't know if we'll be able to effectively create a sustainable living there, without help from those back at Earth. Too early to tell, but even if we could, I don't see massive amounts of development in 120 years.
There's no real reason Lightning wouldn't work in its current form, just with delays to channel opening and closing as described above. Or maybe we end up with a separate Mars blockchain
A separate Mars blockchain would probably be the best bet. Although, like I said I can't see the development of mars requiring a currency for a while. Depending on how successful we are at colonizing the planet, it would likely take many years for there to be an actual need.
It'll be a sweeping statement to assume that Bitcoin will rise in the long term; it can very well be but there are obviously various shortcomings of Bitcoin that are either innate or difficult to solve.
There's some obvious shortcomings that people tend to ignore. Now, I'm not saying that there's another cryptocurrency that does it better, not currently. However, I have said this before, but I believe Bitcoin isn't the ultimate solution to our problems, but rather the building block; the foundation. I'm not sure if Bitcoin will be able to solve its issues within its limitations, reaching some sort of consensus, and succeeding as a currency.
Yes, I agree. Incorrectly expressed his thought, or rather it will be like this: As you can see, over 12 years, bitcoin has made a huge leap in terms of adoption, from a handful of bitcoin geeks to entire countries. In the next 10 years, the reach of bitcoin will become even more widespread.
Also while I agree with ranochigo that nothing is for certain, the labeling within your little timeline is mainly how the media portrayed it back then, rather than having any substance behind it. There was plenty of non nerdy characters around dabbling in Bitcoin back in the day too.
