In my opinion those accelerators are not effective. They basically broadcast your transaction to more miners... but transaction broadcast is not a problem after 6 hours of broadcasting.
Your opinion is completely wrong, first check the facts and then you will see that at least in the case of ViaBTC things actually work if the set conditions are met. Over the years ViaBTC has saved me a very nice amount on fees when needed.
I didn't know about those websites, however they don't look very effective. The minimum fee to get included is ridiculously high. 100 sat/byte. I will still ignore them and keep my opinion
Your transaction is confirmed by Poolin pool, so no transaction accelerator helped you in this case. If you used the ViaBTC accelerator (free), then you may have noticed that it gives you the message that you have too low a fee to take your transaction into account (only 0.00004451) and their condition is a minimum of 10 000 satoshi.
That's ViaBTC's minimum fee per KB, not in total:Quote from: https://www.viabtc.com/tools/txaccelerator/
you can submit any TXID of delayed transactions that at least include a fee of 0.0001BTC/KB
100 sat byte, the minimum, is a very high fee which will get confirmed in a few blocks even when network is congested. Using that "service" or not.
20 sat/byte (OP case) will still get confirmed naturally by some random pool even when network is congested, which just happened. Looks like the benefit of using those services is minimum, if any, because any miner in include a 100sat/byte in a few blocks.
Over the years ViaBTC has saved me a very nice amount on fees when needed.
I think using 100 sat/byte is wasting money. Unless you really need to get into the next block.
I rarely use more than 10sat/byte. 90% of my transactions are 1 sat/byte, and they get confirmed within a reasonable time.
