9361  Bitcoin / Electrum / Re: Fraudulent transaction along with the correct one(Ledger Nano S + Electrum) on: February 19, 2020, 02:01:23 PM
Nothing stops malware from generating transactions and sending them to your ledger for your to accept/verify them.

I'd guess that OP would have seen on his Ledger the new transaction he has to confirm and would have rejected it...
And in such a case this whole topic would have no substance.
9362  Other / Beginners & Help / Re: Consider these 12 things before joining a bounty program on: February 19, 2020, 10:42:16 AM
Before participating in a crypto bounty project, here are some things you need to check in order to save time and problems later with the project.

A list like this is necessary. But.. you could take 10 extra minutes and write it better, taking care to
* structure it better, meaning not take the same/similar idea in multiple lines (see 1+3; 6+10;2+11)
* not make mistakes yourself "if they have a lot of mistakes, quick quit soon"  (also, actually not join at all, right?)
* remove unnecessary points (some get long term jobs which "resonates with your passion", so let's not be such purists)

So the list is good, but you can make it great with a bit more effort.


PS. I also agree with @JeromeTash that "weekly" payment is a rule one cannot follow because there are (almost?) no such bounties.

9364  Bitcoin / Electrum / Re: What is electrumx server? on: February 19, 2020, 07:28:03 AM
I have seen at least 3 different electrum server software, one is literally called "electrum personal server" and its quite light.

I want to remind you that OP was asking about ElectrumX.


Truly paranoid people should stick with core, or cherry pick the servers they connect to (yes you can choose).

Truly paranoid people should not connect to the internet. Ever.
This being said, everybody will have to research and choose what suits him best according to how paranoid he/she is.

I don't think that cherry picking would help much in most cases, since even "known good" servers may get reinstalled with something else. So the real options are SPV or not SPV.
For me SPV is "good enough" for daily use. If I'll ever get rich I might reconsider that  Grin
9365  Alternate cryptocurrencies / Mining (Altcoins) / Re: Blocks rejected when solo mining but accepted on pool? on: February 19, 2020, 07:18:12 AM
Did you set the conf file correctly? Afaik you have to do a little more than just start the wallet/daemon.
I don't know if this is (still) OK for the coin you mine, since it's 5 years old, but it could be a start: https://bitcointalk.org/index.php?topic=521563.0
At least the
Code:
server=1
listen=1
daemon=1
part may be of interest.

Also most of those miners may be behind routers with no packet forwarding available one could reach them (unless you hack the routers, of course).

A newbie has posted not long ago Medium link on this same subject. It may worth a read, I don't know, I still didn't completely understand it.

9369  Economy / Trading Discussion / Re: Exchange managed to lose 7000- 13000 BTC in Non Payment?(BTC downtrend reason?) on: February 18, 2020, 02:00:58 PM
And we all go back to the good old trust.

Heh, as long as some exchanges still operate after not giving back user funds after hack, inside job or whatever,
as long as people still keep massive amounts of coins in the exchanges instead of their own wallets,
as long as exchanges still have customers after fishy behavior (see Kraken users getting strange hacks with multiple levels of 2FA on, see Yobit token machine).. the trust seem to be .. unnecessary.

I guess that we deserve our fate, really. And sorry, but exchanges are supposed to be financial (not banking, but not too far) institutions after all, since we talk here about coins and tokens with real value (at least some of them), not Monopoly money.
9370  Alternate cryptocurrencies / Speculation (Altcoins) / Re: I have bought Yoda and Alisa. Should I continue holding them? on: February 18, 2020, 10:49:19 AM
I have bought some Yoda and Alisa coins in Yobit.

Did you read at all about them before investing?
There are some rules on investing in altcoins:

[1] Never invest money you don't afford to lose

[2] Invest based on what you think, not others

[3] Read about the coins before investing and after you invested too, from time to time. Some have a real future, development, good idea and will rise over time. Some only show empty promises and have to be avoided. Some stop / slow down the development and probably will not succeede because of this. Some others only have a bad time when the funds leave the altcoin market,  but may recover at some later point.


It's hard to find the good projects, but I have a feeling you didn't do your homework (see [3]) and you've picked coins you shouldn't have.
However, do your reading and decide for yourself what to do.
9371  Economy / Trading Discussion / Re: Exchange managed to lose 7000- 13000 BTC in Non Payment?(BTC downtrend reason?) on: February 18, 2020, 10:00:39 AM
There should be some kind of regulation, everyone can create an exchange and then just steal the funds, like what we see here.

There's quite a contradiction. Regulations, among other things (including the fact the owners may be prosecuted for theft) bring the so much hated KYC (so the prosecutors get to know which individuals the funds are stolen from).
Don't take me wrong, I am pro-regulations for companies, but it's hard (actually impossible) to keep everybody happy.
9372  Economy / Reputation / Re: Is franky1 making libellous statements about BitRefill? on: February 17, 2020, 06:40:46 PM
Imho he is 100% against SegWit and LN as part of Bitcoin, hence he's trying to convince everybody (by all means!) that Bitcoin going in this direction is a mistake. This sums it up.

PS. Obviously the "by all means" part is the problem.

The team have decided to close the campaign due to low response from forum. Everyone is free to remove your signature.
9374  Bitcoin / Electrum / Re: What is electrumx server? on: February 17, 2020, 02:01:34 PM
there is nothing important that a malicious Electrum node can fake. for example they can't give you a fake block header without having to mine it first!

Indeed, they cannot fake the Bitcoin headers, I wrote pretty clearly what did they actually fake.
All I could have been adding was that with the newer versions of Electrum the messages to be sent are handled different (hardcoded?) and even that cannot be exploited anymore.
But this was not relevant for the discussion, the relevant part was the fact the server node may not have to do anything special in order to have clients connected to it.


i strongly dislike calling them "servers" because it makes it look like a centralized thing you connect to.

In my mind server is something that serve i.e. offers its services (usually for free).
But I don't mind, node is good too.
9375  Bitcoin / Electrum / Re: What is electrumx server? on: February 17, 2020, 12:23:08 PM
People connecting to your server doesn't necessary meam that they trust you.

Actually I think that the last year's Electrum hijacking was made with a couple of malicious ElectrumX servers (telling that Electrum needs update and sending out the link to their malicious Electrum) and DDoS on the legit servers, making the users connect to the hacker's servers.


I have tried to google it but none of the answer could have satisfied me.

I guess that the main page to read is https://electrumx.readthedocs.io/
Shortly yes, it's a "node" (or better: server) for Electrum.
9376  Bitcoin / Bitcoin Discussion / Re: Bitcoin's transaction fee lowered by 4000% on: February 17, 2020, 11:10:06 AM
It's cheaper than ETH transactions.

Yep, and still the (brainwashed?) Bcashers continue with their false advertising even in this thread, and now I'll even answer to that.


* Coins in Blue process more transactions per day than bitcoin at a lower fee than bitcoin. *

One blue has similar or higher fees, one is a worthless shitcoin that has low fees because nobody is using it and the third is not a proper decentralized coin.
9377  Bitcoin / Hardware wallets / Re: Yes, the Keepkey is a worthless black bricklet on: February 17, 2020, 07:39:22 AM
At least it can be used as doorstopper.
Too light, even for a cat door.

It can be used as decoy if you ever face the 5$ wrench issue. Just give them your KeepKey  Grin
9378  Economy / Speculation / Re: Buy on Friday and Sell on Monday on: February 17, 2020, 06:58:11 AM
The researcher found that the average lowest price of bitcoin was at  6 am UTC time on Fridays and the best time to invest or buy bitcoin.

If you would have done this in the week-end just passed, you would have bought at around 10240$ and sold at 9790$. Not a good business.
The morale of the story is: don't just go by various self-called specialists, some don't know sh*t and Bitcoin market is more volatile than the "rules" they want so badly to find out.


Still the market price of bitcoin was volatile the study is justs getting the average so you cannot rely on this analysis all the time.

This is the only correct part of the analysis imho.
9379  Bitcoin / Bitcoin Technical Support / Re: Very slow synchronizing with Bitcoin Core on: February 17, 2020, 05:55:45 AM
Last time I needed a full sync I made a symlink onto the SSD only for the chainstate and it did wonders.
And after the sync I moved the chainstate folder back to HDD.
9380  Bitcoin / Wallet software / Re: importing seed to another wallet on: February 16, 2020, 11:15:29 AM
I know that I can import them for the same wallet but can I do that as well with another wallet?

If you created the seed with Ian Coleman tool or a hardware wallet (or anything following the standards), it will work in other wallet too (eg Electrum), you'll just have to set that it's a BIP39 seed and set the correct derivation path.
If you created the seed with a recent Electrum it may not work with anything else because Electrum also adds extra info in the seed (eg version).  You can read more here: https://bitcointalk.org/index.php?topic=5203955
