They are using Bitpay as the payment processor which unfortunately Dash is not on. We have approached them recently for an integration and were quoted a ball park figure of $100k to get it done
Has it occurred to you that masternodes are paid over 2 & a half times that amount every single week - even at these prices - for doing next to nothing ?
We've had this discussion already but perhaps I'll try again to summarize it here as succinctly as possible what was already said across multiple posts...
You are correct, as Dash is, masternodes are paid too much... then again there is an argument for rewarding early adopters and those that risk their capital despite you disregarding it.
In any case, you might have heard that Platform (or whatever it may be called) is in development and may actually be released this year. Everything I read indicates that there will be a cost to use these new services so the economics of Dash will change. Will masternodes be even more overpaid? Could be but until a closer thing to a complete product is available and we see what kind of demand it garners we're both just speculating.
