First transaction is confirmed, can someone please help me to accelerate the others?
Looks like they've all been confirmed now... all mined by ViaBTC in 2 different blocks...
Is it free to accelerate transaction? Same here, almost 3 days still unconfirmed.
Yes, the ViaBTC accelerator is free as long as you meet the 0.0001 BTC/KB minimum fee... and your transaction isn't relying on unconfirmed parents and isn't a double spend etc...
The only other issue is that they only accept 100 txes per hour... they reset the submission at the start of every hour and it fills up VERY quickly so you have to be quick.
