To ever leave BTC on any exchange is stupid given the recent history.
Agreed, although I find as a pragmatic matter that there are usually crumbs left over at an exchange after most withdrawal transactions.
Not to pull a Godwin, but somehow this factoid (from Wiki) springs to mind when I think about the Bitstamp story:
"The classical period of witchhunts in Europe and North America falls into the Early Modern period or about 1400 to 1700, spanning the upheavals of the Reformation and the Thirty Years' War, resulting in an estimated 70,000 to 100,000 executions.
The last executions of people convicted as witches in Europe took place in the 18th century. In the Kingdom of Great Britain, witchcraft ceased to be an act punishable by law with the Witchcraft Act of 1735."
Plus ça change.
