Well it looks like that won't be at least for a couple weeks according to the chart. Why do you think bitcoin would tumble when gold typically goes up? Also, when did this belief that bitcoin is tethered to tether start?
It's all about expected return. $1300 to 70k is a lot better use of capital than $1300 to $2400. I really doubt anybody has traded from $1300 to 70k in gold PnL..and even if they did they had to grind it out..a hodlr just napped his way to 70k :)
