Okay, so one of his option is to wait for the average fee rate to drop below 44sat/vB.
Judging by
the way fees are dropping, that may actually happen today.
Or if he want it to confirm faster, paying for a legit accelerator services will be expensive for 1000vB+200vB (approx) transactions.
He will have to pay about $500 to those pools.
I checked: ViaBTC charges $270.
