Haha found this funny article:
https://www.forbes.com/sites/adamhartung/2017/08/15/a-bitcoin-is-worth-4000-why-you-probably-should-not-own-one/?sh=40081f113b08Pay attention to the date it was published (Aug 2017). The conclusion was the best part haha:
Unless you are a professional trader, or you simply want to gamble, stay away from Bitcoins. They have no inherent value, because they are a currency which represents value rather than having value themselves. The Bitcoin currency is not managed by any government agency, nor is it backed by any government. Bitcoin values are purely dependent upon holders having faith they will continue to have value. Right now the market looks a lot more like tulip mania than careful investing.
So beware guys, Bitcoin is a bubble.

I am curious what he will do after he sees this bubble

Maybe he is crying not involving in bitcoin.
There must be thousands of such articles. That one was published in Forbes, which is prestigious, but I think a compilation of articles warning that Bitcoin had no intrinsic value and the like would be enough to write a book.
Btw, thanks to xhomerx10 for designing my new hat.
Key word here is
intrinsic value.
Had a conversation with two very intelligent guys recently, both worked on AI, and both were very sceptical about BTC (one mostly because he thought governments would never accept losing control over money). I explained to them that the intrinsic value of BTC is absolutely there, only organised differently then in traditional companies. BTC has a great number of capital goods, only they are decentralised, coming and going, in the form of miners and full nodes. BTC has IP, only it is open sourced. It has development, only also more decentrally organised. They found that enlightening.
But of course the biggest intrinsic value is that it actually works to safely and immutably exchange value and store other valuable information.
And then there is this inflation thing.......
