With XRP facing a SEC lawsuit and suspending its trading or could possibly lead to delisting in some major exchanges like coinbase,okcoin, OSL another top notch coins are facing same dilemmas as XRP. Bittrex announced the delisting of Monero(xmr), Zcash(zec), Dash(dash) but gave no reason for doing so. By the way these 3 coins have 1 thing in common all of them are are ones of the so-called privacy coins, not only bittrex  is doing the move but actually there are some other exchanges had already made their move. Any thoughts about it?
