> By mid 2013 [..] the thief had taken out about 630,000 BTC from MtGox.

630,000 BTC to USD = 1,560,069,000.00 US Dollars

Crazy.

$1.5 billion USD = 2.5% of Bitcoin's market cap ($40 billion) and someone stole it.

Around Mid 2013 Bitcoin supply was around 11.5M coins so 630K was more like 5.5% of total Bitcoin. Just using a different kind of math. There's more coins now so using todays market cap % makes it seem less then it actually was.

But mid 2013, the price of Bitcoin was ~$100.. So 630k was "only" $63 million. A much larger percentage of a much smaller asset.

Of course, there is almost no way to liquidate those BTC for $1.5 billion. Unless you can find a buyer for all of them at once, the market price will fall sharply as you sell them off.
