I definitely think the next comment has to be true if the willy bot scenario is true https://www.reddit.com/r/Bitcoin/comments/3fe92x/im_ashley_barr_aka_adam_turner_the_first_mtgox/ctor4f3
It's basically this, which was very insightfully written at the time:
TL/DR: A young man had a secret. To keep it hidden, he kept digging until the hole was a billion dollars deep. This is a speculative tale of a great bitcoin theft from MtGox in 2011 and the efforts that this man undertook to fix it. The tale explains the bitcoin bear market of 2011, the explosive rally of 2013, delayed fiat withdrawals, malled transactions, and a bot named Willy.
Holy mother of God. This is it. This makes sense.
I don't know why I suddenly and instantly believe this theory, but it fits all the pieces so perfectly.
But when was the Willy Bot active? I understand how it could guide all markets since things all started on GOX and that is where the liquidity was.
But as other markets developed good liquidity, why would they still follow GOX so closely? At the end they stopped following GOX, right as the Shizz hit the fan.
My point is, why not ANY of that before? (Outside of a small price disparity.) This is more a practical question regarding when other exchanges surfaced with their liquidity perhaps.
Perhaps GOX just had a liquidity monopoly until, it obviously no longer had one.
