Tried using this and paid, so far it has been 8 hour since my payment and no confirmations yet. I do hope it is worth it that I spent extra just to accelerate a transaction. Man, the network is so congested right now, I guess this is brought about the sudden increase in price of bitcoins and as a result a lot of people wanted to move their bitcoins around.

I have a question though, the site said that if the transaction does not confirm in 72 hours you will give a free accelerate on the next one. How do you log with ones to give a free acceleration to, there if there is no login?

Edit: Seems like the owner of this site has not been online for about 7-8 days already (last seen December 3, 2017). So I am guessing this is just an elaborate scam, oh well, shame on you for running with my $4 if this was indeed a scam.
