Yes, the same Bitfinex part and parcel of the Tether fraud, which has created $25 billion USDT, backed with "reserves", which operate exactly like banks. They make "loans", and then use that as the backing for their balance sheet (among other dubious methods of "reserves").
Okay, chart time. What you're looking at is:
On Top: XMRBTC price in orange and the ZECBTC price in blue
On Bottom: Net longs for each coin, XMR orange, ZEC blue, and BTC in gray for reference. *See note
*Note: For XMR and ZEC, it includes BTC longs-shorts. It also divides by 30 day SMA of volume, to factor out changes from skewing the chart. As evidence, look at BTC, in gray, similar magnitudes as Monero.
So ... some partie(s?) on Bitfinex started longing ZEC with increasingly large fluxuations starting in mid 2018, continuing until present day. The amount of longs vs shorts as a ratio of volume appears to be exponentially increasing.
Until recently, XMR and ZEC mostly matched each other for price direction (if not magnitude). However, suspiciously, the net longs seem to have little correlation. This doesn't make sense for two coins who *were* competing for the same use case (the competition is over, Monero won).
Worse, for apparently no reason at all, last year, at exactly the same time that Monero price began to diverge upwards from ZEC and Monero was quickly distinguishing itself not only as THE accepted currency for DNM, but also as one of the best performing coins of 2020 ... we see something which hasn't occurred since 2018. XMRBTC net longs drop drastically into the negative, far beyond at any time in it's trading history, while ZEC has yet another larger exponential move into net-long. This occurs immediately before the XMRBTC ratio drops out.
One must ask, how is it possible that these two coins have such widly divergent action on Bitfinex longs-shorts, whether or not the corporate interests behind the largely defunct zcash have anything to do with this, whether this has anything to do with the fact that Monero has dropped precipitously relative to other coins, and what part Bitfinex plays in this fraud.
Probably alot, given that the defacto state of their relationship to Tether is nearly synonymous with Tether, and it is likely a significant factor in the price action of the past 6-9 months.
