Bitcoin will always yoyo forever siphoning money from those with less market knowledge to those with more market knowledge (or ability to manipulate it) until there aren’t enough people in it anymore. They aren’t making money, just moving it around.

I agree with that assessment.
Bitcoin is just another tool to move money from uneducated people with fomo to those who hold the strings.
Technically it’s obsolete, but I’m glad it paved the ground for some innovative approaches to transfer value anonymously or very fast and with cheap transaction fees or even no fees at all.
