an article that talks about price all the time and calls that "success" is not worth reading in my opinion. bitcoin's success is not about what price level it is going to reach, the price is only the byproduct of the actual success which is defined as how decentralized bitcoin is and in short how much did it stick to the basic principles that are defined for it

That's perhaps what some of us believe. Most investors atm, especially those spamming HODL everywhere, are mostly interested in Bitcoin for its price rising. Its value as an investment cannot be a means to an end. Currently, Bitcoin is mostly just severe wealth redistribution. Most general investors, when pressed, end up accepting its issues in practical use and make clear their belief Bitcoin is some "store of value", and believe that's sustainable or practical. I don't think it is.
