Hello. Please do you have any recipe how to make the cheapest possible transaction with many inputs 5 or more to 1 output and yet make it the cheapest ? I need to do the transaction through an application , I don't have the PC option . It keeps giving me high fees whether it is 50$ or 150$ , I try all options , mempool , static...and no acceptable reduction in TX fee. Thank

Firstly, which wallet are you using because transaction fees are moderate now and you should not be spending much on it. You can use https://mempool.space/ to check the actual fee needed to transfer your bitcoin so that it can be added to the next block.

Electrum accepts adjustments of fee manually and I think that will be the best thing that you need to do by checking it on the me pool and set the fee to the right amount shown in the mempool for such amount that you are sending. It is because you have spending from 5 outputs as one input, the fee will be high. You should use mempool and not static.

Since you are using a phone, this can adjust fee by moving the fee adjustment to the right or to the left before clicking pay.

Give me from Amount to send 0.0007 mbtc lowest mempool fee 0.0874 mbtc and write alert : Please note: The fee for this transaction seems unusually high. (1248.57% of amount).

I guess you have more than 5 inputs. That is one of the reasons you can see the warning of fee is unusually high on Electrum. My advice is to use coin control to freeze the coins with lower coins.

On Electrum mobile version, click on your wallet name -> addresses/coins'. At the top right corner, click on addresses. Then click on coins from the drop down. Freeze the coins that are small in amount that are dust. Leave only the ones that are high in amount. Then go and proceed with the transaction.

I froze all the addresses , and it still shows the same amount of charges , after freezing it should not give you the option to do a higher transaction than the allowed funds ... The wallet is installed on xiaomy 13 Lite ... could be a problem in the phone ...?

Please note: The fee for this transaction seems unusually high. (860.00% of amount) - I want send 0.001 mbtc , All coins are frozzen...

[Charles-Tim]

Go and unfreeze the addresses.

I posted that you should freeze the coins and not the address. But unfreeze the addresses. I guess that the bitcoin denomination confused you which is the issue you are having. 0.001 mBTC equals 0.00001 BTC which is very small.

After you unfreeze the addresses. Do this:

At the top right corner, click on the green circle. It can be in blue if you are using Tor and it can be in red if not connected. After you click on the circle, click on preference. Change the base until to BTC and go and make the transaction.

I guess you want to transfer 0.001 BTC and not 0.001 mBTC.

The amount is too small. 0.001 mbtc = 0.000001 Bitcoin. Send more than that.

Yeeaaah Thaaaank you !!! IT IS goood...

The Coins tab is like an advanced tab for those who want maximum control which is why it gives you the full control over which coins to spend while disregarding the frozen address.

You're on Android Electrum, right?
For Coins (UTXO), after toggling to show Coins: tap and hodl the UTXO for about 3 to 5 seconds and "Freeze" button should appear below the screen.
Frozen UTXO are displayed with purple square icons.

This is because you have spent all the coins and you have no coins to freeze. If you are receiving coins on the address or addresses that the wallet generated, you will start to see yours UTXOs (coins) that you can be able to freeze.

Thanks you very much...👍

To avoid something like this then avoid receiving multiple inputs on the same address all the time  because it's not good for your privacy in the first place even, although coin control has been a life safer so far but what if you have to spend it all at once..
Then incase you have the chance to consolidate your inputs when the mempool is very low  with not too  much unconfirmed transactionif you ever found yourself with more inputs(not including  dusts ), Do it and wait it out to drop into the new address

The OP issue is not about having multiple inputs, it is about not knowing the difference between BTC and mBTC. He was sending 0.001 mBTC which is 0.00001 BTC or 1000 sat which is very low amount of coin which cause the warning on Electrum. He has changed from mBTC to BTC denomination so he can easily understand the amount he is sending and I think it has no issue of sending again.

Okay! initially I was actually focused on what OP said in his First post  below.

It keeps giving me high fees whether it is 50$ or 150$ , I try all options , mempool , static...and no acceptable reduction in TX fee. Thank

Really thought OP was trying to send a BTC worth of $50 to $150

Please note: The fee for this transaction seems unusually high. (860.00% of amount) - I want send 0.001 mbtc , All coins are frozzen...

Just seeing this now .... although 0.001btc is close $50( just saying ) which is so different from mBTC.

I've moved away from using mobile Electrum, but does that mean that Electrum still shows balances in mBTC and not in BTC by default?

We wrote about it here a few years ago and I got the impression that it will be changed in new versions, because it is confusing for every new user, and I really don't see why the developers so persistently don't want to change something that would make it easier for many to use this wallet?

By default, it is still in mBTC.

Yes, It is better in BTC. Also another suggestion would be that the fiat currency should be in checked by default. Even if it is in mBTC and the fiat currency is checked by default, this may not be a problem because the amount to send can also be seen and written in fiat.

I haven't seen any discussion here that involves the developers about changing the default unit, perhaps it's posted by someone unaffiliated with Electrum?

Anyways, it's just a 1 line of code if we're just talking about switching from mBTC to BTC as the default unit.

But I'm hesitant on creating a pull request since the potential issue here is to those who haven't set the default unit
and comfortably using mBTC, thus there's no "decimal_point: 5" in their config file.
Once they, upgraded to a version that changed the default unit, they might send unintended larger amounts if they do not pay attention to the new version's default unit.
(e.g. 0.1mBTC but sent 0.1BTC instead)
Users who previously set it to any non-default value then switched back to mBTC default shouldn't be affected since the "decimal_point: 5" saved in the config should persist.

If anyone want to push that, feel free to create a PR that changes this line: github.com/spesmilo/electrum/blob/76f5d6ceb07b49e403f63488832fd6cb397ee91b/electrum/util.py#L95
from: DECIMAL_POINT_DEFAULT = 5  # mBTC
to: DECIMAL_POINT_DEFAULT = 8  # BTC

It makes sense, but sometimes a problem can arise in the value of the transaction, considering that Electrum uses several sources with fiat values ​​that can be different. I once had problem with payment through Electrum because I chose the amount in fiat, but that amount ended up being less than the amount that should have been in BTC - unfortunately the service refused the payment. It is safest to pay the amount in BTC.


@nc50lc, I didn't mean developers, but us forum users who have read dozens (if not hundreds) of such topics where new users got confused because Electrum shows mBTC by default. I personally don't have a Github account, but if someone thinks it would be useful to change that, it might be worth a try.
