Actually, you are not correct. The top holders have only added more XC to their portfolios, not dumped. They know the future is bright for XC.

They are dumping. Last week top 10 possess 33.3% of all the cap. I think XC already dead. And falling in abyss with light speed. URO looks much promising
XE aint dead, seems its a pro team we new fresh ideas. But it ll take a while to get to the top. They need to implement features of other (temporarly) successful altcoins. One coin dat can replace other coins. LOTR-mode: On ring to oppress them.
But for next little success and daytraders like me: Need moar ETAs (REV2 and REV2.5).
