ViaBTC accelerator is full, so you have to use btc.com (expensive, AliPay) or ask certain users (for a fee) - from what I've read Quickseller is one of them.
Viabtc now also offers a paid accelerator service in addition to its free one. You have to email [email protected] to use it, and it costs 0.01BTC for each transaction. It's explained at the bottom of the free accelerator page.

Has any one here used this expedited accelerator service
and is this also available in real time considering only way to contact them is through their email address which is not the fattest of communications
