let me crunch some numbers (please tell me if i made any errors anywhere):

- deposit $1000 to bitstamp and pay $5 fee
- buy $1000 worth of bitcoin in (on? at?) bitstamp at $1170.88 you pay $2.5 fee and get 0.85192333BTC
- withdraw bitcoin to kraken and pay nothing! or 0.1% with bitgo (apparently)

- sell bitcoin at $1186.54 and get $1010.54 and pay $2.62 fee so you are left with $1008.21
- withdraw to your bank and if you pay the same fee as bitstamp you end up making $3.21

this is 0.32% profit. if you think the risk is ok such as price changing up and down, withdrawals getting stuck and taking long, ... then do it.
