I have witnessed weird things on the Kraken, like a day or two before the 2015 crash down to $150 on all the other exchanges. On the Kraken somebody briefly dumped the price down to that level two days in advance when the price was far higher elsewhere. The dump was over in seconds, but the buyer got dirt cheap coins. The Kraken has thin markets, but that trade struck me as weird nevertheless.

If we're lucky those Kraken 589.30300€ candles might be an indicator of the price on all the other exchanges in a few days.
