Your tx has 49 inputs, so the volume is far higher than what ViaBTC free accelerator accepts, it also does not meet their criteria in fee/byte. But your tx is rbf enabled, so if you cannot wait for the node you are connected to drop your tx, you can use rbf to bump it by replacing this tx with a new one paying a higher fee.
I think he wants to consolidate his input. He can increase the fee if he is in haste.
The transaction vbyte is around 4500
The mempool right now is around 218 sat/vbyte
At 100 sat/vbyte, the fee to be paid woukd be around 0.004501 BTC. Bitcoin at $44050, the fee is $198.27
At 200 sat/vbyte, the fee to be paid would be around 0.009002 BTC . The fee is $396.46
I think that amount is huge in fee. I will advise him to wait until the mempool become less congested. But he can increase the fee a little bit higher. Like 50 sat/vbyte. Or maybe the mempool will still become lesser congested.
OP supposed to have consolidated his inputs before this time. 2 sat/vbyte still got confirmed in November.
