I beg to know more information about these people who have proved that it's all a bubble. I'd like to know what part of math and science is proving that Bitcoin is a bubble, about to burst. Despite rumors and assumptions, I'm yet to see any solid evidence, as you're mentioning.
Strange that you didn't notice @proudhon, everyone already knows him in the speculation board, and he is especially popular in the WO board because of his eternally pessimistic attitude. His sources that have confirmed his theories with the help of mathematics and science are supposedly from China - at least that's what I remember from some discussions.
Here is an example of his post from 2016, and any further discussion after that is completely unnecessary - 6 years later he is still defending his opinion, and the value of 1 BTC has grown from $400 to the current $47 000.
I've been studying bitcoin for years now, and have fully confirmed my fear from a few years ago -- that ultimately bitcoin is doomed to failure. All the data I've seen confirms this and anyone can check it with analysis of their own by technical analysis data, as I have confirmed. Just check the Chinese and Russian sources, as have been confirmed by my TA analysis and multiple linear regression study.
The best course of action at this moment is to sell if you have bitcoin and not buy bitcoin if you don't have bitcoin. That course of action is confirmed by the available data and will prevent losses. I'm simply offering this advice to help people not lose money on a dying technology. Feel free to review the data yourself. It's very clear. These news, data, and charts should be concerning and demonstrate with confirmed facts that bitcoin is nearing the end of its life. Maybe something better will come along, I don't know. But unfortunately, bitcoin has failed and is collapsing.
