Actually, it's simple. It's all about supply-demand. As the transaction supply increases, transaction fee increases.

It's also about the number of miners in the system. As the number of miners increases, the ratio of the demand is increased and the fee falls.
You can still find a great&technical answer in mining section if you want. There are a lot of thread in there.

I need to read it few times in order to understand the main problem you wants to share. Are you getting problem in blockchain wallet especially about the fee? I'm using blockchain wallet in my android phone as well, but I have never experienced any issues. If your main problem is in deciding the fee you need to pay to send, blockchain gives you 3 options to choose and I usually use the priority fee so my transaction will be confirmed faster.

I think this website is good to visit if you want to see the latest paid transactions fees
https://bitcoinfees.earn.com/

According to this website the "the median transaction size of 224 bytes, this results in a fee of 2,240 satoshis." for a median bitcoin transaction today, but that number can change each day.

Right now you can just use the lowest possible fees your wallet allows you to do, and your transactions will go through within in a few blocks, and not more than one hour.

Here you can see the numbers of unconfirmed transactions, waiting to be sent

And here you can see how many real transactions that each block have

I barely understand what you're saying, but the gist of it is that you want to know which fees are appropriate without having to test yourself, right? You can use this website:

https://coinb.in/#fees

I find that this one is better than other common fee estimators, as a lot of those often inflate the minimum fee recommended.

As a sidenote, it's higher than usual at the moment (but still low in the grand scheme of things) so you should wait if possible.

The idea you have is almost what I think Op is asking. Yes I think the transaction fees varies, from the miners and how fast you want the blocks to be confirmed. I know that segwit bitcoin wallet gives option for a faster transaction but with additional charge.

The links posted above given two very different fees for different situations.

https://bitcoinfees.earn.com/ gives the minimum fee to try to confirm in the next block with a >90% chance. In real terms, this means your transaction is likely to confirm within 10 minutes (on average). If you need a transaction to confirm this quickly, then choose that fee. At time of posting, that fee is 18 sats/byte.

https://coinb.in/#fees gives a fee for your transaction to be included "within the next few blocks". This can sometimes mean waiting a couple of hours or more, but works out much cheaper. At time of posting, their recommended fee is 2 sats/byte, or only 10% of the previous fee. If you are not in a hurry, you can safely choose this fee and just be patient.

Another useful site is this one https://jochen-hoenicke.de/queue/#1,8h which will give you a visual representation of how full the mempool is, and may help you to choose a fee somewhere between the two suggested fees given above.

i believe that this website is mainly designed to be useful newbie and not that much for anybody else because they always intentionally give you a higher fee because (again i am assuming) they want the transactions with that fee to be confirmed with 100% chance. so for example if it tells you 18 s/b that means you can get away with 5 s/b too.

I really can't understand the thought of your post. But for what I understand, I think that you're asking what will happen to the fee if the price of btc go up? I observed that the fee is just getting bigger if bitcoin goes up. So, if bitcoin goes down, the fee will also go down.

If that's what he's asking, then the answer to that is it depends on the platform. In the wallet I use, the lowest transaction fee is .000018 I think but it is so slow it could take up to 3 hrs. And for hitbtc the price of fee is .001 or so. In bittrex that's the fee also. It depends on the platform.

Like other people, you need to make a simple question, so we know what your means is.

Ok, here is my opinion.

Let say you install Mycelium, and you have a balance, for example, $100 in bitcoin. Then you want to send $25 in bitcoin, but you don't know how much the fee.

You can look at the image below:


You can use the scan QR code to add the wallet address or use the other option, add the amount of bitcoin. Then in the lower in Miner Fee, you will see how much fee you should pay. You can slight to the right to see how much the difference of the fee. If you don't want to wait too long, then you can use Priority ~ 10 minutes to get arrive. But usually, it won't take too long, and sometimes it's only less than 1 minutes to get confirmed in the network.

I hope that is what you want to know.

For the benefit of every stakeholder, bitcoin holders and traders may accept a considerable amount of transaction rate. Using and enjoying a service without paying means nothing for the future of bitcoin, but also an over-priced transaction fees can make people keep away from investing and trading.
