My arbitrage:
1) Buy large quantity and hold in paper wallet.
2) Buy smaller amount and hold in hot wallet.
3) Spend smaller amount.
4) Replenish smaller amount.
Repeat.
Guaranteed earnings. Promise.

Heh, that is really cunning plan. But I am really interested in experiences of people who have been actually doing arbitrage. With this constant 2% spread on average between exchanges, there must be some people who profit on this. Am I the only one making money on BTC arbitrage?
