Multibit HD to electrum or BRD ?

[HCP]

@HCP so after have been verifying 2 or 3 times, I finally added the fees and the total match the balance showed in BRD slow sync or eletcrum.

Crazy that the fees made such a huge difference to the balance! That's quite a substantial amount spent!

I am gonna continue to better understand what was these 3 transactions that don't appear in Fast Sync. Do you have any the idea why these 3 transactions didn't appear at first ?

The only reasons I could see for them no appearing in the fast sync would be some sort of "Gap Limit" limitation (ie the system was simply not generating enough "new" addresses to check and missed those 3 transactions) or it was caused by some sort of timeout in the sync process.

I'm not overly familiar with BRD as I haven't used it in years (As I recall the app wouldn't run on rooted devices and I was heavily involved in Android Custom ROM development at the time so was using rooted devices) so you would need to talk to the app Dev(s) and ask them why the fast sync misses those transactions... fastsync is some custom system they have developed to replace SPV, so it might be a bug that they can fix.

Yes...not cool. Do you think @HCP there was anyway to escape this "substantial amount"?

I would like to have more info about BRD Fast sync, but for the moment I have not. I am gonna send a new message. I am trying to recover old multibit HD transaction history to see if these transactions are in it.

I am a little bit confused about this balance 0.38 => 0.04. I am gonna dig a little bit.
I will tell you if i get more info.

Thkx for your help to make me understand this craziness

About the only thing you can do is use a wallet that allows the setting of custom fees and try to be more aware of the network status at the time you go to send a transaction...

https://mempool.space/ and https://jochen-hoenicke.de/queue/#BTC,24h,weight give good overviews of the current state of the network and with a bit of practice you can determine a "decent" rate that will suit your purposes (ie. cheapest option, don't care about how long it takes to confirm vs. must be next confirmed in next block etc).

A lot of wallets try to simplify fees to things like "low", "normal" and "high"... but don't give any indication as to what those rates actually are (or mean)... and because the network can be quite volatile, you can end up over (or under) paying by a substantial amount!

I'd have to look at all the transaction details to see exactly why your total fees paid were so high, but the normal causes are:
- Using legacy UTXOs as inputs. Legacy UTXOs are much larger than SegWit UTXOs, so using older Legacy addresses will mean that when you go to spend the coins, your transaction will have a larger total data size. As the total fee is (size * fee rate), then logicially a larger total data size == higher total fee.

- Using multiple inputs to a transaction. Having multiple inputs (Regardless of SegWit or Legacy) will result in a transaction with a larger overall data size. As above, larger data size = higher total fee. This is usually the result of collecting a lot of small amounts of BTC from mining or faucets etc and then trying to spend them all at once. Can be somewhat mitigated by occasionally consolidating your inputs when the network is not busy and the fee rates are low. That way, when the rates are higher... you'll likely only need 1 input and the smaller transaction size helps offset the higher fee rate required.

Hi @HCP,

Well, in fact I didn't touch the wallet since 2017. Between 2016 an 2017, I made many transactions. Now when I am looking at the history of multibit HD in the panel, I don't see any fees https://snipboard.io/zsugFD.jpg. This screen capture is today.

When I export the csv file from multibit HD, I have these 'transactions fees that appear', I don't really understand because I didn't notice these fees in 2016-2017. https://snipboard.io/VqDgCs.jpg

The only transaction I made since this period was with BRD 2 weeks ago, and they have a mode slow (=low fees), and it was transparent. No huge amount.
So where these fees come from, I don't know.

I have to admit, it's quite technical for me. In 2017, I didn't know nothing about bitcoin. And I still don't know so much.

https://mempool.space/ and https://jochen-hoenicke.de/queue/#BTC,24h,weight give good overviews of the current state of the network and with a bit of practice you can determine a "decent" rate that will suit your purposes (ie. cheapest option, don't care about how long it takes to confirm vs. must be next confirmed in next block etc).

I thank you very much for this information. It will help me.

I am gonna try to understand this.

If you have time and if you want to have a look at the csv file, you can give me your mail, no matter for me.
You are a great help since the beginning but I have to confess I am still in the smog. I should follow  a course on the blockchain

If you actually click on the invididual transactions, it should show you the fees. A lot of (most? all?) wallets don't show the transaction fee on the transaction history page... it is usually only shown on the transaction detail page.

The transaction history page will usually show you the total amount that was spent (being the total sent + transaction fee).

I think some of this confusion has simply been caused by the fast sync giving you an incorrect balance, when you then believe to be your actual balance... and then the shock of seeing the actual balance as reported by Electrum.

The money hasn't been lost or stolen or anything like that... it was simply an issue with the BRD fast sync (and to a certain extent your memory) reporting an incorrect amount which lead you to believe you had more coins than you actually did.

Great, thk you @HCP for this trick

Yes, I understand about

the fast sync giving you an incorrect balance,

.

This fake balance was very close of what I thought I had lost.

What a pity, but that's life!

Thank you very much for all your posts, explanations. It has been a pleasure to exchange with you.

Kind regards
