All "bitcoin accelerators" that were not offered by any mining pool is obviously scam. What i know about accelerators offered by mining pool are viabtc, antpool (free), and btc.com, but unfortunately the two of them stop their service.
There are two more legit ones but of course paid, Binance as it owns a pool and mempool.space as it has a deal with foundry.
They want people to pay $1067 for instant priority. Lmao.
With instant being between instant and one hour, with just yesterday a block taking more than 70 minutes to be mined you can see why only a noob or a scammer will use time instead of blocks when advertising this.
People said there is no evidence that they are scam, but definitely they are scam, including the here one that you have justed posted here. They are all scam.
I just hate this whole thing that is right now spreading though the forum where you must have complete evidence and there must be a victim who will dox himself, prove ownership of funds, prove the funds where received by the scammer and before anyone would have the right to accuse that guy must also KYC himself and send a sperm and blood sample to the jurors.
We've reached a a point where someone trying to sell a bridge from Cape Town to Tokyo for 2 BTC is not a scammer till somebody actually buys it!
