6221  Economy / Economics / Re: Basics of the Current Monetary System on: October 11, 2021, 04:43:15 PM
It could be a great lesson in fiscal responsibility, but more likely what would happen is that they would come up with some new fractional reserve system between various governments and central banks which would allow them to spend 100 BTC for everyone 1 they actually hold.

But, why would they legalize and enforce Bitcoin usage if they continued using a fractional reserve system? Correct me if I'm wrong, but such system works only if there's demanding for new loans AND available reserve from the clients' deposits.

For instance, I may not want to move around with $10,000 neither to store them in a closet, so I'll deposit it in a bank and feel safe. But, with Bitcoin there's no need to worry for such scenario. It can be hidden much easier than with cash. You also don't need to move around with it, as you can send most of your coins to a cold storage.

In the current monetary system, your bank is useful. You use it to transact with. When it comes to withdraw your funds, they give you an IOU which can be used as currency.

I may have messed up some things again, but it seems to me that the easiness Bitcoin provides replaces some functions of the bank. Currently I need the bank to transact online, so I'm forced to increase their liquidity. With Bitcoin, I won't have to.

Can't I recover it?
Chances aren't with your side.

How many incidents like this one do you (plural) need to understand the importance of the seed phrase? This is your money. You can't have really forgotten or chosen not to write it down. Ledger must have warned you about that.

However, I have the backup file of Electrum. I can still open it, but I can't send coin.
Does it say that it's a watch-only wallet?

Would it be possible for some amazing kind person to write the script for me? I can't code.
What kind of script? You can calculate the addition of those public keys really easily. Just take a program, such as Secp256k1 Calculator and fill the proper fields.

Once you add those two points:
Code:
x: 4BDC661EFDC05C536E1E116B9E059D0E36AA3A25253E18DFC0DDEFD4FACF36F3
y: 22D570A7D46E4F19E3D94869FEF6894ADFA93771837F36B03D3E8341FB15B62C

x: 05FC50574C83CC70A20BDE37F637F76EC53F7780A8FE6C4A4EA7EE9641FD5D39
y: C9523862EBE583E5A9B1423DDC54C789EB332DD9D30A2939CB10258D88987C1F

You'll get this one as a result:
Code:
x: 937192A2BA413909EA6AED1CA53E0AA294736BBB6F41164D159E0A7392926C00
y: 56AFE970031AD898FE0AAD818C133E131122EE682E8FF9C3F1DAB493754999EF

Since it returns you coordinates, it's not outside the curve.
6224  Bitcoin / Development & Technical Discussion / Re: First Bitcoin, then Blockstream Satellite. How about we go fully decentralized? on: October 11, 2021, 06:22:17 AM
It's nice seeing that there's always some sort of enthusiasm for a new invention. The intelligent part of this innovative technology is that it incentivizes you to think likewise.

I think that one of the problems Bitcoin will be facing over the long term is the aftermath of some disastrous events. I'm talking about events leading to internet blackouts or power cuts.
I think that's fearmongering.

Everything is built to operate online; the whole world moves (and has already moved) their businesses to the internet. There are stores which only exist in the internet. Part of the education system is done from distance. The communication etc. Saying that one of the problems Bitcoin will face is this kind of disastrous event is trembling the least.

Lots of other events will occur in such scenario which will affect the economy much worse.




BTW, lightning doesn't always require internet connection.
6225  Bitcoin / Bitcoin Discussion / Re: I am new to Bitcoin and have been using Coinbase only. on: October 10, 2021, 07:53:28 PM
there is a good chance your bank can reverse all the transactions and get your money bank.

I don't think that's the reason why getting stolen in a bank is better than in an exchange. A thief can spend your money much faster than you'll realize you have to somehow reverse the transaction. Not sure how a bank can tackle this problem; how can they reverse a transaction if the thief has already spent the money and not deposited them somewhere custodially.

It's the insurance. Coinbase can get hacked or pretend of being hacked and you can do nothing about it. On the other hand, the bank may provide you insurance in case of such incident.
6226  Alternate cryptocurrencies / Altcoin Discussion / Re: ANY STRATEGIC IDEA ON LONG TERM INVESTMENT IS HIGHLY NEEDED on: October 10, 2021, 07:13:47 PM
If you want to invest in the long term, you probably want to bet with the lowest risk. If that's the case, go with Bitcoin. It has a bright future, it may be globally adopted this decade when central banks introduce their digital currencies.

But, if you just want to make yourself richer at the expense of other investors, then you deserve not to. Sorry.
6227  Bitcoin / Bitcoin Discussion / Re: The top 3 the best anonymous wallets and practices to anonimize Bitcoin in 2021 on: October 10, 2021, 06:57:55 PM
I use wallets https://trustwallet.com and https://bitcoin-wallet.org I believe that they are completely anonymous, because no personal data is required during registration.

Being anonymous doesn't mean you avoid revealing personal data such as your name, phone number, passport etc. Anonymity is the condition where there's NO WAY for an individual to work out your personal information. For example, if you give someone your IP address, you are not anonymous. The fact that your name remains unknown to them doesn't mean it will remain forever. There are ways one can locate you based on your IP address; first ones? The government.

The wallets you mentioned are not recommended if you want to remain anonymous. Instead, the greatest anonymity you can achieve in Bitcoin is by using a non-custodial wallet which is connected to your full node which is also connected to the Bitcoin network through Tor.

That's the highest decree of anonymity Bitcoin offers you.
6228  Bitcoin / Bitcoin Discussion / Re: Bitcoin(Cryptocurrencies) is a social movement? on: October 10, 2021, 06:42:36 PM
Do you consider Bitcoin(or cryptocurrencies) in general a social movement?
I think that anything revolutionary is involved in the social movements. Bitcoin doesn't dictate anything to anyone. Its freeing nature is what attracted most of us.

It's more like a social phenomenon.

Is there a formal organization behind Bitcoin?
This forum we're using at the moment to discuss supports Bitcoin as a social movement. Anyone can create an organization that supports it, but it's better if we move as a team, in one place. Again, it has to do with its freeing nature; you can do whatever you want with it.
6229  Other / Archival / Re: [POLL] What to expect from Bitcoin in 2022? on: October 10, 2021, 06:31:42 PM
I think that as time goes by, we should be even less optimistic about huge changes. It's not a million dollar market cap joke anymore, but a trillion. Billionaires can't affect it, the same way they could in 2013 or in 2017. I don't know what will really send it to $100k-ish, $200k-ish, $300k-ish etc, but my opinion is to enjoy what we currently have.

This asset has proved it's gaining more and more attention long term. There's even more speculation which stabilize it in a way. I think that it's meant to succeed and hell yeah, I want to be part of it and increase my accumulation position.

Μόλις έστησα έναν υπολογιστή με μια 3060 lhr και θέλω να κάνω mining με 2 νομίσματα στον trex.
Τι εννοείς θέλεις να κάνεις mining με δύο νομίσματα; Επίσης τι είναι ο trex;

Έχω κλείσει Καθε ασφάλεια των windows και πάλι δεν συνδέεται.
Θα πρέπει να μας εξηγήσεις σε ποιο pool προσπαθείς να συνδεθείς και τι βγάζει κάποιο log. Δεν μπορείς να λάβεις μια βοήθεια αν δεν διατυπώσεις το πρόβλημά σου σωστά.



Επίσης, το νήμα ανήκει στο Mining Discussion (Ελληνικά).
6232  Economy / Economics / Re: The Economic Problem on: October 10, 2021, 09:14:39 AM
Therefore, the economy has to answer three questions
You've forgotten the fourth question the economy has to answer. How will we increase the quantity of the produced products, which means how will the economy of a society grow.

Sorry for the title giving the wrong impression.
It's not that bad choice. The problem you described is the main economic problem, not just the economic problem. It's the one in which every other economic problem comes from.
6233  Bitcoin / Bitcoin Technical Support / Re: Electrum - How to create more Receiving Addresses? on: October 10, 2021, 09:01:00 AM
wallet.change_gap_limit(number)

Instead of this solution that requires to restart Electrum, I'm providing another one that doesn't have this requirement.



Go to View -> Console and type:
Code:
for i in range (n): print (wallet.create_new_address(False))

If you want to generate receiving addresses or:
Code:
for i in range (n): print (wallet.create_new_address(True))

If you want change addresses. Replace n with the number of addresses you want to generate.
6234  Bitcoin / Bitcoin Discussion / Re: I am new to Bitcoin and have been using Coinbase only. on: October 10, 2021, 08:51:47 AM
You could liken Coinbase with a bank. The bank holds your cash, you hold a so-called IOU. If the bank goes bankrupt or if they get somehow stolen, you'll lose your money.

The administrators of the exchange hold the keys. They've just given you an IOU which says that you own an amount of coins. Bitcoin was created to avoid this middleman in your online transactions. Coinbase is required to buy bitcoins from, but not to be used as a wallet. Instead, you can be the owner of the keys and ensure you're the sovereign of your own wealth.

If you're interested in this technology I'd recommend you to work on Bitcoin. It scales with second layer solutions such as the Lightning Network and it's far more practical. If you're attracted on smart contracts, such as Ethereum's, Cardano's, still; work on Bitcoin. It's not advisable to start from a much more advanced project as a newbie in this field. It's like knowing nothing from programming and start your journey with javascript.

Here're developer's guides: https://developer.bitcoin.org/devguide/
6236  Other / Beginners & Help / Re: Who else has your passphrase on: October 09, 2021, 01:43:43 PM
You don't have to give them your passphrase/seed/private keys. You only need to make them learn some stuff, like how Bitcoin wallets work etc; you should just sign a transaction which spends all of your money (you want to inherit) to a freshly generated address which will be owned by your family/loved one.

Just make it spendable after a certain block and ta-da! Trustless inheritance.
6237  Economy / Economics / Re: Basics of the Current Monetary System on: October 09, 2021, 07:15:23 AM
In the case of the USA, I see that it is 0%.

Yes. That is true as of 2020. Since keeping only the 10% makes the supply 10 times greater, imagine what happens when they keep no reserves. This is when the “∞/21M” meme/joke became famous. The infinity symbol indicates the current money supply.

Indeed, since there's no limit in the currency inflation, you ought to be protected from a safe haven asset, otherwise you'll be pulled to poverty one way or another. Whether that asset is gold, Bitcoin, stocks etc. Although, I think that based on what's waiting us, Bitcoin is the best choice.
6238  Bitcoin / Development & Technical Discussion / Re: [Guide] How to run a Bitcoin Core full node for under 50 bucks! on: October 09, 2021, 07:03:45 AM
Great guide n0nce! The headline takes the cake.

And keep in mind, if you want to go RPi you don't need the cool looking case. 4GB RPi4, USB drive, microSD and power supply. If you take your time and look for sales you can easily get it for under $130.

But, isn't the case required? The CPU will be running 24/7/365. It won't live as it would with the cooling case. At this point I'd like to say that many have hard drives lying around, me included. Just use one of those.

This is why it came €90 to me.

  • Raspberry Pi 4 Model 4 - 4GB. (€52)
  • Power Supply of RPi. (€8)
  • Memory card 32GB. (€6.5)
  • Argon One aluminum case. (€24)
6239  Bitcoin / Development & Technical Discussion / Re: Where to get large amount of testnet coins? (~2.5BTC) on: October 09, 2021, 06:48:10 AM
Interesting thought; however I'm not sure what else could motivate them.. Do you have anything particular in mind (even if just pure speculation)?

Well they have to either sell them in a market or use them in a way to have a greater income than outcome. Since I don't believe in the latter, I'd bet that there're people who buy them. Still, at the moment each block gives a tiny amount of coins, but it's too expensive. I can't really speculate anything farer.

I remember I had created this thread back when I had more, similar queries: What's the point of mining testnet bitcoins?
