I just wanted to know if those paid services of Bitcoin transaction accelerators will help in this case like ViaBTC since it has many partners in a mining pool.
I never had experience using the Paid service of ViaBTC accelerator but since they own a pool they can be able to speed up the transaction.
By default, a pool like Viabtc prioritizes transactions that pay higher fees automatically. However, The pool owner or the pool operator can manually choose what transaction they want to add to the block.
So Viabtc's paid service should work in this case the only problem is the paid service is a bit expensive.
