One thing I immediately noticed this morning, is how much USD-T had gained relative to its normally inconspicuous (boring) deviation (lack of change).
It's obvious now.
If I can personify a moment, Bitcoin doesn't like money moving in and out. If we thought Ethereum was like a turtle, over-reacting and pulling its head into its shell at the slightest movement, Bitcoin is a rabbit racing off into the grass.
Someone with smarter math skills than I can calculate the volatility, but it is obvious from looking at this graph, and we should have been well aware that a very quick draw-down was ahead. Until we see some relative calm (like we did preceding these past weeks, we will continue to have difficulty moving up in any meaningful way.
