There is also BitAccelerate for those who wants to take a shot in using a free accelerator service. Though with my experience on this service, they aren't as quick as ViaBTC or Antpool's.
Bitaccelerate don't accelerate your transaction at all. They only rebroadcast your transaction and that's different from accelerating.
I really don't understand why some still use BitAccelerate it says there clearly:
Our service will rebroadcast the transaction via 10 Bitcoin nodes
it's a rebroadcast system, if your tx has such a low fee that it's going to be purged by nodes then there is no chance in hell it would get confirmed, it would be at least 100 block under , so what's the point? Actually since they don't ask for a fee, what's the point of that website also? Not going to disable adguard to check but other than income ads and donations I really don't see a reason for its existence!
Cheap marketing? Huh. I assume, highest percentage of smart people make RBF-enabled transactions, so, there you have a majority of people who have no idea about RBF and correct transaction fees. This marketing is aimed towards those people to give them a false sense of discount and motivate them to accelerate transaction on Binance immediately.
Yeah, cheap marketing!
Because it's not a product on a market , it's not like you're offering a pepsi bottle 50 cents cheapen than the shop next door, it's not like selling a phone that was 1000 yesterday for 900 now! It's a sum that fluctuates according to the mempool congestion, so saying you offer a discount to a non existent prior price is just garbage!
