I use Coinbase as my primary purchase broker. The official LOW PRICE FOR THE DAY is $277.22 and I guaran-damn-tee you that NOBODY bought @ $13 or 10¢ at Coinbase. They bought at whatever the 8000 ETH were offered at. Even if it WAS $13 or 10¢ it was 8000 ETH, and no more. If that is the case, it is the "F'ed Govt" using MANIP-MANOP to spook the ETH holders. Which would be a STUPID Move, since they just OK'ed ETH for 401K's and IRA accounts.
No, there were people who absolutely got orders filled at $0.10 and $13.00.
