ViaBTC's accelerator, Antpool's accelerator, Transaction announcer services.
These services all work, however they are difficult to time (in the case of VIABTC, requiring you to be on the website at EXACTLY 0:00 on the hour, trackable via UTC time zones) or will not directly accelerate your transaction, rather just adding them back into the queue (where it may sit at the very bottom and remain unconfirmed). What causes stuck Bitcoin transactions?
Stuck or slow Bitcoin transactions are caused by low transaction fees. These are visible by putting your transaction onto Blockchain.info and looking for the amount in "Fee per byte". If it is a low "Satoshi" per byte relative to the current rate, it will get stuck. You can view the current recommended fee here Other ways to fix stuck transactions
Consider looking into "Child Pays For Parent" if your receiving address contains a "chainge" address, or Replace By Fee if supported by your wallet client or the receiver.
