As strange as it sounds, this wall I believe is part of a larger conspiracy, for the exact same walls have been placed in litecoin just sitting there for weeks/months.  I believe the purpose of them is to try and trick people into believing coins such as LTC + Monero can't rise and to try and force speculators into the Eth market to buy horrificaly overpriced Ethereum from the R3 banking consortium/Digital Currency group/other large fucktard organizations.
