The wicks on bitstamp look like stop hunting. But it's the shorts being preyed upon...
Looks more like someone fat fingered a 200 BTC market buy to me, as the price spiked up +4% to ~$29K within a 1 minute candle. High frequency trading bots would have therefore exploited that opportunity.
Usually stop hunting happens over the longer course of time, like 15 minutes to a few hours, ending with a wick above the highs (or below the lows) prior to a reversal...
Either way, if it was stop hunting, it was an epic fail as price only wicked that high on Bitstamp (not on other exchanges) so wouldn't have liquidated many people

For reference sake, Bitstamp has a
pathetic amount of liquidity compared to the likes of Coinbase or even Bitfinex.
There is only 100 BTC sell orders to cover a 5% move to the upside, or roughly 200 BTC to cover a 10% move to the upside...
