another hot wallet - 1CbR8da9YPZqXJJKm9ze1GYf67eKAUfXwP with more 10k roll offs

I think the way gox's wallet system worked was they had a main hot wallet, rolled off X amount (< 10k and > 1k) and then spun 200 btc wallets off of that that performed withdrawals sending the remaining values to subsequent wallets until it was depleted.

When the hot wallet had a value of > 10k they would roll it into 10k "cold" wallets.

Edit: they would also fulfill withdrawals from 2k wallets evidenced from second hot wallet
