Done via Antpool accelerator. Hope it could get confirmed soon.
Today I learned that there are other free accelerator that doesn't have maximum number of request. Credits to
SFR10.
For Antpool you can easily copy paste all of the transactions at the same time and accelerate it (no hassle)
For ViaBTC, you have to do it on hour resets and if you're fast enough you can accelerate two transactions at the same time.
For ConfirmTX, as long as it's less than 400 byte/tx, it will be processed for free (without a limit on number of Tx's).
For Antpool, you have to make an account on their site (that includes SMS verification) to use their transaction accelerators.
