Young but I'm not that bold

there is nothing strange about your transaction fees Wink

. Maybe you used to use blockchain.info wallet and their .0001 btc fees.
AFAIK, in mycelium, you can not write a specific fees. you just can choose between low priority, economic, normal and high priority. and it also differs depinding on the transaction size of course
So I did not send two transactions before with the same fees while using mycelium Grin

give me your cryptos

Mycelium uses their own special server to trawl through the mempool and find out what's the cheapest way to get your tx into the next block. It's not always accurate, but it works. It will try and put it to the lowest satoshi. I base my transactions on cointape.com, because blockchain.info can't do that

... The problem is the interface doesn't allow to see the fee in advance, so we can't see exactly how much we will pay.

Correct me if im wrong.. but after choosing standard/economic/high priority.. Mycelium wallet shows how much Fee is going to be paid..

Thanks, I was wondering about that lately as well, so I just checked and it shows this when I try and send $2.00 USD to a random address (not going to hit send lol):

Amount ~2.00 USD
.00465344 BTC
(Miner Fee Normal .03253mBTC, 0.01 USD)

Well, I will answer to myself in case someone has the same question.

I went through the code and it appears Mycelium use theirs servers to calculate a live optimal fee, based on transaction pool I guess. The fee setting is now a n-blocks confirmation target, based on this heuristic.

The endpoint is this one:

Code:

curl -k -X POST -H "Content-Type: application/json" -d '{}' https://mws2.mycelium.com/wapi/wapi/getMinerFeeEstimations

The problem is the interface doesn't allow to see the fee in advance, so we can't see exactly how much we will pay.

Maybe someone can enlighten me about a strange transaction fee policy I noticed on Mycelium. I just made a payment of 0.015237 BTC with a very standard transaction (1 input, 2 outputs) through Mycelium. However, the fee appears to be quite random: 0.00012349 BTC.

Is it expected, a new behavior? I thought the policy was 0.1 mBTC per 500B or something...

Here is the transaction:

Thanks
