Once you use that services in which you're be obligated to pay some bucks for the sake of speeding up your transaction, you just lost the point of using bitcoin for its cheap fee (even if now's that not cheap anymore).
But well, for some whale, few bucks doesn't really matter as long as their money could arrive fastly. How about just buying a contract on viabtc and uses the special privilege of accelerating transaction? is it worth it?.
