I was not talking about cloud mining or similar, I was talking about paying for having a particular tx mined.
I laughed at most of the replies above because almost all of them are talking about cloud mining without even reading your first post.
I think title is quite misleading and most of the people who have replied above are just posting to increase their post count or to get paid.
I haven't used any paid tx accelerator till now but found free tx accelerator viabtc have really helpful.
