I think this is ordinary pump maybe provoked by recent news. Cryptomarket is still down. There are just whales groups playing with random coins.
"Whales groups playing..." : perhaps.
"...with random coins" : whales never play with a random coin, it is always THE coin they choose, with specifics datas/qualities.
Are you able to predict surely when and what coin will be pumped?

If not, PnD events look like random for you. Many coins is sutable for pumping. There are not many ways to get profit on stagnant market so PnD events are observed easily now. In recent days a series of PnD have been commenced. RVN, EXCL, RADS, ZCoin yesterday and more.. Of course whales did preparation work before pumping. About 200 Znodes magically disappered just about pump started

I believe zcoin price will return to last usual levels or slightly higher in several days.
