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:
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.
you don't understand how viabtc accelerator works. It does not particularly care. if you do 1 sat or 100 sat it does want. the fee to be.
0.0001 or higher. so if you have a send that has tons of bytes. and you add to over 0.0001 it works.
This occurs when you may have had 25 or more deposits in a wallet and the transaction is 1000bytes at 10 sats you cross the 0.0001 and it works great.
If the transaction has 250 bytes it won't work since you paid 0.0000250
So some mine at nicehash and other pool they get a weekly payout of 0.0010 btc and don't move the coins from the btc addy until the years
end
it is 50 x 0.0010 btc or 0.050 btc and it is 50 x 250 = 12500 bytes.
you could pay. 5 sats = 0.00062500 btc. over the 0.0001 total fee threshold and viabtc works fine.
for free. zero problems
in fact you could pay 2 sats. and it would be 0.00025000 btc and be over the fee level for viabtc to work.
Now if you pool allows a threshold setting and you keep the coins pool side until they reach 0.01. that is the same 0.050 btc but only 5 x 250 = 1250 bytes. you need to pay. 10 sats for a total of 0.0001250 btc and viabtc will unstick it.
I have issues with btc payments from people when I sell gear.
The send. 1 sat on a 250 byte could be .100 btc. and the money gets stuck. viabtc does not work. in that case. cause they paid.
0.00000250 btc which is under the 0.0001 viabtc rule.
