This kind of argument shows up a lot, but is a classic example of "appeal to popularity". Whether bitcoin goes to $0 or $1,000,000 is mostly irrelevant when discussing technological and practical merits of bitcoin.
Where the price of bitcoin is relevant is when discussing it as a speculative investment. So what tends to happen is a conversation that was supposed to be about blockchain technology turns into one about blockchain speculative investing. This and appeals to greed/FOMO ("have fun staying poor") tend to drive me nuts about a lot of blockchain discussions.
> A lot of anti-bitcoin crowd gets ego invested in their opposition, and the result is articles like this, which misunderstand the fundamentals of bitcoin.
If a "no-coiner" has high ego investment in their position, what level of ego investment does someone holding cryptocurrency have? And what specifically does this article misunderstand about the fundamentals of bitcoin? Just stating that the article misunderstands something is not a very strong argument or rebuttal.
