Using an absurd 75% - 20 day envelope on the chart which I think does the job of identifying extreme stretches for this stock. The recent pull back is reminiscent of a blow off the top formation. Don't see why RIOT couldn't halve back to the $30s in the coming weeks even with bitcoin above $50K. Should finish today with a bearish engulfing.

Please note this is also a log chart, so it may not naturally look stretched, but for a log trend this is stretched.
