We sent all clients an email about this. If you didn't seem to get it, please check your spam folder. (Our email provider inexplicably sent all the emails out in about 10 minutes when they should have gone out over the course of hours, so many of the emails may have been marked as spam.)
The email didn't address the fact that the new fee structure is a substantial increase for our national currency pairs. As I've already said above, this should have been addressed in the email and I apologize for this omission. We don't expect anyone to be happy about the increase - who is going to be happy about paying higher fees?
It's been so long now that probably it's been entirely forgotten, but our current fees were originally intended as an introductory rate. From the OP of this thread made back when we launched:
...we offer you discounted trading fees, and love, of course—at least during the first month
Instead of offering the discounted trading fees for a month or two, we've kept the discount going for almost a year. We understand if the discounted rate has been in place so long that it now seems like a standard rate. But in fact it's always been a discounted rate that isn't sustainable long term given the resources required to run an exchange.
Could we somehow slash our operating costs and make the current fees viable? Even if this was possible, it's never been our goal to operate a bare-bones exchange service. It's always been our goal to offer an exceptional exchange experience at a reasonable rate. The new fee structure may seem high compared to the current deeply discounted rate, but it's still very reasonable compared to many other exchanges. Remember that it's not just trade fees that matter. When evaluating the true cost of an exchange, you also have to consider other factors, such as the cost of depositing and withdrawing from your account. We still have the same low fees we've always had for depositing and withdrawing euros from your account (basically free for SEPA).
Again, we always appreciate your feedback because we're always striving to better understand and meet your needs. There are of course limits, however, when it comes to fees. We're here for the long-term and we need to have a sustainable fee structure that better reflects the true costs of our services.
