Before Bitcoin appeared, we seldom doubt the reasonability of currency.
As a matter of fact, wealthy entities did that, hence they kept their funds "locked" in gold, art, properties, ... name it.
Correspondingly, paper money is gradually fading. I believe in the next two decades, cryptocurrency issued by private company and legal electronic currency launched by the central bank will replace paper money. Perhaps, in the few decades to come, paper money will indeed disappear.
A way of "currency" that doesn't need electricity, internet and such may have to keep remaining in use in certain regions of the world for quite more years. I think that while the "few decades to come" can cover over 90% of the population, the remaining will need (exponential?) more time.
5. Bitcoin is the best value storage carrier. Bitcoin itself is valuable. Future currency will also be anchored by Bitcoin;
While this has indeed pretty good odds to happen, it may make it even more a "digital gold" than a "currency". I have mixed feelings whether this would be good or not.
And as a side note: while the post is informative for those who don't read much, it's also (too) long, hence those who don't read much may not read it all (and the informative part remains just wasted time for those who - more or less - know the history). An idea you should think on is to reduce your posts' length
where possible.
Hi, NeuroticFish, thank you for your advice. These articles of mine are indeed very long, and it will be tiring to read them. Many friends also gave similar suggestions. I now try to shorten the content as much as possible in the writing process. But in many cases, it is really difficult to reduce. Many of these articles of mine belong to philosophical thinking. Not only do I have to give a conclusion, but I also have to write the process of reaching this conclusion. This causes a lot of text to appear verbose. They will certainly not be liked by most people. However, I think it is still necessary. They may be suitable for some friends who like to think deeply. With my writing level, I can easily write many short works that are popular with most people in the forum, and cater to most people's preferences. However, this is not what I want. I hope to organize my fragmented thinking into systematic knowledge. There is an opportunity to publish these articles into books in the future. As part of the evangelism for Bitcoin. I believe that in the next five to ten years, as the global consensus on Bitcoin continues to strengthen, more and more people will realize the value of my articles.
