The Price at Kraken DID NEVER reach 2000/BTC or higher yet.
These are bugs in trade engine or anything like that. That happens usually ~once a month, but in times like this it happens more often...
Nearly every exchange is unreliable at the moment.. also bitstamp has stuck orderbook quite often these days...
If it didn't reach that price why would Kraken site itself list it as the high price today? Were is it getting the data if not from its own trading engine?
Are you really sure no trades were executed at that high price after bypassing the entire order book?
Is there any place I can access a log of all trades executed?
