Looks like a SCAM to me Looks like a SCAM to me, I tried to contact support but the site said "The form was unable to submit. Please contact the site administrator". I emailed them through acceleratebtcnitro.com and yet no answer.

Since a few people here decided to post… Since a few people here decided to post 1* reviews, I thought I'd share my own experience. I paid for the premium service and had my transaction confirmed in less than 3 hours. I contacted support who repleied in about 20 minutes (I think they cover CET timezone) and were very helpful. Can't ask for much more than this!

Customer support gives quick feedback… Customer support gives quick feedback on issues and does everything in their power to help move your transaction along as quickly as possible. 10/10 would recommend their service and will use again if ever needed.

I paid for the Premium service and am… I paid for the Premium service and am not getting responses from support or the website working. It says 'The specified UID does not match any of our records.' EDIT: Support started responding after I posted this review but my transaction is still unconfirmed 48 hours later. Starting to feel like this service does nothing and only refunds if you don't naturally get your transaction through and if it does they keep your money. 0 connection to pools. EDIT2: This service did nothing to help with my transaction, I paid, I waited and nothing happened. They do exactly what I described earlier, take your fee if it gets confirmed on its own or refund if it doesn't. It is a scam.

Worked really well Worked really well! In a couple hours, the transaction was confirmed. Highly recommendable
