Which version of Electrum and where did you download it from? Here you can find older versions of Electrum (don't forget to uninstall the one you currently have installed if you decide to try out other versions). Users seem to encounter this issue on Windows 7 and Windows 8.1. The dialog box from the image you uploaded suggests that you use Windows 8.1. Make sure that your OS is up-to-date.

What is the largest transaction for you? Do you mean the transaction size or the amount of bitcoins which were sent? If the latter then this page might be useful for you. It shows all transactions with the biggest amount of BTC sent in the past 24 hours.

Actually, Ledger released model Blue which had Bluetooth support a long time ago. However, none of the built-in apps took advantage of this feature. Why both Ledger and Trezor haven't released proper Android apps which would work well with their devices? Support in Mycelium is a bit out of date (no SegWit) and the app itself became shady. I agree that there are plenty of good software wallets for smartphones, for example, Samourai which can be used for on-the-go payments.

Localbitcoins is basically trading with other people in your local area face-2-face in most cases (lower risk of getting scammed). You could also try looking for Bitcoin ATMs but they are still rare, especially in small cities. I used to buy Bitcoin directly with my debit card but many websites which provide such service have a minimum amount of dollars which you have to spend. CoinGate is a pretty solid one but they also enforce some kind of verification. You might pass it, though.


You have to talk with the other person about it. 100 dollars is obviously not the same as 100 euro. PayPal payments are reversible so that's why some people might be reluctant to trade with you.

As I wrote above, due to the increase of transactions, the fees have gone up significantly.


Which version of Electrum do you have? The latest one should have Replace-By-Fee enabled by default. After clicking "Increase fee" you should see a slider which will allow you to set a higher transaction fee. There are currently 5 thousand unconfirmed transactions so it's slowly getting better. If it isn't urgent, wait a couple of hours and your transaction will be confirmed.

Sposób złożenia aplikacji nie jest jakoś specjalnie trudny. Wspomniałem już o tym w którymś z moich poprzednich postów.


Dziękuję wszystkim, którzy wyrazili chęć przetłumaczenia moich poradników. Osoby te zostały odpowiednio nagrodzone. Mam nadzieję, że mogłem choć trochę pomóc i postaram się wymyślić inny sposób aby móc przesłać trochę merita adekwatnie do włożonego wysiłku i poświęconego czasu.

It looks like there has been a spike in the number of transactions recently. The recommended transaction fee is 12 sat/byte which for an average transaction (1 input, 1 output) is about 2300 satoshis. It is ten times more than what you have paid. What wallet are you using? I would recommend you either Electrum or Bitcoin Core if you prefer software wallets. Your transaction will be confirmed but you have to wait a few more hours.

As I mentioned in my other thread, this problem has been addressed in the v0.5 release of LND. I have just edited the topic and included proper explanation. I have also included a few questions which were answered by me in this thread.

TREZOR is currently porting trezor-core (new software which is used by Trezor T) to Trezor One so that it could take advantage of new features and coins. However, Monero might not be supported due to hardware limitations (memory problems) but TREZOR team is trying to address this issue. Monero has had a few hardforks so the firmware you linked is a bit out of date.

I have done a little bit of research and I found this piece of code with good commentary.


As you can see, since the CLTV time-lock didn't expire, you had to wait until it was "incubated". Here you can find a graph which will help you to understand it more easily.

Hardly anyone will agree to do that. PayPal payments are reversible while Bitcoin transactions are not. You can try your luck here but I guess that nobody will be interested in your offer since you don't have any trading history on bitcointalk.

Are you trying to say that using Electron Cash with a hardware wallet is insecure? In fact, it is secure and the same applies to Electrum. Trezor never exposes your private keys. You have to connect your Trezor only during the wallet creation and when you want to sign a transaction. Trezor is busy with more important things, for example, adding support for native SegWit addresses directly to their web interface. Beside the code changes, they would have to run nodes following Bitcoin SV chain.

"maturity_height" and "blocks_til_maturity" are your answer. 144 blocks is about 1 day so you should get your funds back in approximately 5 days. Similar problem has been described here. There must be something wrong with timelocks. Have you used that channel? Did the other party have zero balance?

Rozumiem, że mogłem zabrzmieć trochę dwuznacznie. Przez pomoc miałem na myśli wytłumaczenie jak działa cały system. W takim razie zostawię to Wam i po prostu nagrodzę najlepsze odpowiedzi


Zgłosić kandydatów musimy w dziale "Meta". Zazwyczaj każdy kandydat ma swój własny temat. Następne kilka dni chciałbym spędzić na rozdaniu części merita, który zgromadziłem przez ostatnie kilka miesięcy. Tak jak napisałem wyżej, większą ilością zarezerwuję dla osób chcących przetłumaczyć moje poradniki napisane po angielsku. Dwa o Lightning Network zostały już zarezerwowane przez @wwzsocki.

It's not possible to connect to all nodes at once. Thirteen connections is still quite a lot (take a look at this discussion). Even if you connect connect to a few hundred nodes, you won't be able to download blocks faster since every block must be verified by your Bitcoin Core instance (the processing power is a huge limit in most cases). The same applies to sharing blocks and filtering data for lightweight clients once you change your -listen parameter to 1.

Trezor servers run Bitcoin ABC software which means that on the 15th November they will follow ABC's proposal. The other chain won't be officially supported (no replay protection and splitting tool) but it will be possible to claim those coins using Electron Cash.

Z tego co się orientuję to nie ma polskiego merit source. Z chęcią podjąłbym się trudu złożenia aplikacji, ale potrzebne by mi było wsparcie od Was. Muszę też trochę porozdawać swoje merity (na ten moment mam dokładnie 127). Jeżeli ktoś przetłumaczy jeden z moich tematów o Lightning Network to jestem gotów nagrodzić taką osobę 5-15 meritami w zależności od wybranego tematu (link do moich tematów).


Weź pod uwagę, że większość postów na polskiej grupie to wypowiedzi typu "Dlaczego BTC spadło o $100?! Bańka pękła?". Poziom tutaj jak i na polskim forum jest znacznie wyższy. Z chęcią mogę Ci pomóc z meritem, możesz śmiało napisać do mnie wiadomość.

The input is a nested SegWit address. All four outputs are native SegWit addresses. While creating a new wallet in Electrum, you can select whether you want to use standard addresses or SegWit ones (bc1). Using SegWit addresses allows you to save a lot of money on transaction fees (more detailed explanation here). You can learn more about Segregated Witness (SegWit) here. Native SegWit addresses are also used by every Lightning Network software. Channel funds are locked up in such addresses.

Fortunately, not. Bitcoin Cash is a fork of Bitcoin which can have 32 MB blocks and doesn't support SegWit. It can process more transactions than Bitcoin thanks to the increased blocksize but barely anyone uses it. We are now focusing on off-chain scaling (the Lightning Network, RSK, Liquid Network) which brings us new benefits, for example, instant and cheap transactions while not doing any harm to the decentralization. I would be more concerned about mining pools but it's better for them to make a long-term profit on Bitcoin mining rather than try to double spend some coins.

The estimated BTC transacted is zero because you sent those bitcoins to yourself (the same address). You have combined two inputs into one which is a good thing to do when the transaction fees are low but you did it accidentally with only two out of ten transactions which you have received. Here you can see it more clearly.
