Wish I knew the reason for the surge in interest in XCR - over 6000 sats and 64 BTC volume on Polo, also 2900 sats and 16.8 BTC volume on Bter. Crypti does offer the same features as Lisk without the inflation, so maybe one or more people want to continue on with it as an alternative platform given the huge interest in Lisk.
Probably the same reason that occurs when 'random junk coin' increases in value several times.
Someone is pumping it.
They probably realized that with so many XCR tied up in the Lisk ICO, there is hardly any out there... and most activity is on one exchange ... not so hard to move up now, especially since they can try to tie Lisk success to XCR somehow.
Of course any logical person would look at this as being insane. One party (Lisk devs) will own almost all of the coin, and after the refund period is over, could create never-ending sell pressure if they wanted to.
