I understand the idea behind 'bid walls', but on Kraken, prices are being kept low through the use of 'sell walls'. The volume on this exchange is too low to have a chance of getting through these walls, even when prices on other exchanges are skyrocketing. Every so often, when the price falls a bit, up comes a new 'buy wall' keeping it there. The price on Kraken falls when other markets fall, but gets stopped at the wall on the way back up. I am curious to know what the strategy behind this tactic could be.
