However if you look at the volume traded, versus the total market, I think you get a different picture.
Or is it possible that these people have grown to trust bitcoin, seeing it as a savings vehicle outside of the usual currencies?
I think scams are an obvious harm, but the highly financialised and speculative nature of crypto is a more subtle harm: most investment produces positive material side effects like products or services, but because the main selling point of crypto is to continually pass it around in a circle, a lot of money, time, and expertise is wasted on something that is completely unproductive. To be fair, I think this criticism mostly applies to Wall Street too, but most people no longer try to argue that Wall Street is a source of meaningful innovation. To say nothing of the proof of work model leading to ever increasing energy consumption during climate change.
I just don't see much real upside to the crypto industry, and quite a lot of downside.
