I've really prefer to use Shapeshift for many of small transactions than to trust an account with my money and details. I know it's more expensive, but it's quick and on the fly. So to answer your question, it's 0 since the amount is never actually deposited in any exchange.
I use them too because it is accountless for any transaction/exchange with a lot of available alternative cryptos and the wait time is instantaneously.
Pretty amazing system if you ask me. I am a happy customer with them
Exactly, I don't really understand how many prefer to leave huge amounts of BTC in exchanges. I mean I understand you set a price and forget about it (either for buying or selling) but you are definitely at risk. Poloniex seems the best option from what I've heard. Does anybody knows exactly HOW much expensive Shapeshift is compared to other exchanges? I know how it works, it takes the value from other exchanges and takes a cut, but I've always wondered how much is the price difference between using Poloniex for example or Shapeshift.
