I understand what most of you are saying. However why can’t anybody answer this question:
On cex.io the price to buy 1ETH is much higher than the price to get it back + the fees...
For example it costs 800$ to buy 1ETH but when you sell back 1ETH you receive much less. So not only are there fees but there is also a price difference.. How can one trade successfully if the exchange rates are like this. Can someone please comment this.
