Alright. considering the tether fiasco... If that all settles down, this idea might very well still be valid. On coinbase, and bitmex we didn't see the over-reaction of binance and bitfinex. In fact it topped out at 7000 and the 200 MA, exactly like we've seen here.
If Tether does correct though, it does kind of mean that BTC should be trading around the 6400 range on all the exchanges, and not in the 6800 to 6900 range.
