Almost everyone is wrong, and only because; Bitcoin is not at all about all the deep dips but the stabile growth with the high peaks. That's it and that's all of what most of them just don't get.
But if you look at it, everything is wrong with Bitcoin specially in the beginning,
- Founder is anonymous, we just know connotate Satoshi Nakamoto with Bitcoin
- Magic internet money
- Mt. Gox the first big crypto exchange was hack and up to this time we are still being haunted by it.
And so with that, everyone has it's pessimism, others who make money have sold early and now regretting their decision. Prices goes of the roof in the last 10 years, and now we are looking at least 6 digits as it's next all time high. With that, no one really knows that after all this wrong and whatnot, Bitcoin still survive and continue to grow.
