I just got an email from Kraken:
Fiat to digital currency trades:
The old fee structure ranged from 0.30% to 0.05%. The new fee structure ranges from 0.35% to 0.10%. Why the increase? The old fee structure was a promotional rate designed to support liquidity during our first year of operation. The promotional fee structure is not sufficient to sustain the level of service we provide and wish to continue providing. Fast execution, innovative features, exceptional support, high security - that's what Kraken is about.
Digital currency to digital currency trades:
The old fee structure ranged from 0.20% to 0.05%. The new fee structure will range from 0.10% to 0.05%. Why the decrease? Our aim is to strive for simplicity and encourage trading in selected alternative digital currencies in order to support the digital currency ecosystem. Further, we are delisting several pairs which means that some trades may now require two hops where they previously only required one.
Is BitBot able to handle those changes?
