guys i don't think that transaction acceleration for TX hash bitcoin is real.
the most of that is bullshit i think,can someone confirm it?
acceleration is possible if it is done by the miners/nodes itself by including their preffered transactions
but confirmtx never show or explain his affiliation with any current working miners
read page 5-6, you can see a few complains and no responses from confirmtx
a few more unanswered complains in his (confirmtx) other thread

There are other accelerators but all free ones are crowded and you should use caution when using paid ones.
