Both are scams. There is no such thing as a transaction accelerator these days (except the ones provided by a trusted pool like
pushtx.btc.com). ConfirmTX, spdybit, btcspeedy... They were all scams.
And you don't need one anyways. The
mempool is nearly empty, so you can send a transaction with a 2 sat/byte fee and get a confirmation in a couple of blocks.
