Hi, rok sivante nice to meet you. Let me answer your questions as good as possible.
Yes, you are right, merchants hate the price volatility of Bitcoin and want to get a stable currency that does not kill their margins. That is why we convert all income currencies like Bitcoin, Ethereum, Litecoin, Dash etc. all into BitUSD. Actually, the Merchant has a choice of +5 receiving currencies ( USD, EUR, CAD, CNY, ARS). We are working on providing a 1:1 payout from BitUSD to USD too. So that the merchant is as secure as possible. That is a great selling point for our terminals.

Fees

We charge a flat .5% fee to the consumer, and it works like a small tax. So when you want to pay for a bottle of water 1,5 USD + 0.05% fee. We additionally have to pay a small Blockchain network fee of max $0.04 for miners etc. We even have a few merchants who will cover the fees themselves so decrease the friction with the consumers.

Marketing

We have set up an international BlockPay Ambassador Team currently +50 people in +28 countries to promote and represent BlockPay.
