How much do they charge for their services?
i think it depends, but the other day i wanted to try their service for my .005btc transaction and they did ask me for $6+ so i didn't tried it and I'm not sure if my transaction will be confirmed in the very next block since they claim they are cooperating with other pools
So, let me get this straight, you wanted to send roughly $6 and they wanted to charge you $6 to do that. Wow, where do I sign up for this kind of rape fest?
Obviously, from first sight, no one is going to proceed with this unless there is an urgent need to have that transaction confirmed. That being said, aside from what this service is charging people, in some cases transactions do need massive fees in order to confirm. Good example is those that make one transaction from plenty of smaller dust transactions, which will result in you needing to pay a fee that is holding a higher value than the transaction itself. We don't know if this is the case with the person you quoted. No way to know since information is lacking.
