1  Other / Beginners & Help / Is there any fully open-source cryptocurrency portfolio tracker? on: March 26, 2021, 12:28:26 PM
I'm looking for a fully open-source crypto portfolio tracker but I just can't seem to find any reasonable one. Most trackers out there are on GitHub but have no reputable history behind and since I'm not a coder, best thing I can do is just rely on what other coders say..

I find it weird to give a closed-source software information about how many coins I own, when I purchased them and so on. I feel like this isn't an information to share with a 3rd party.

Do you know any open-source tracker that I can use?
2  Bitcoin / Bitcoin Discussion / With a clogged network, users will start abandoning BTC for alts. Change my mind on: March 11, 2021, 12:13:18 PM
I've been around the space for many years but I do not remember seeing the Bitcoin mempool this clogged ever before. It's becoming exhausting even for me to keep paying high fees. For example, due to the necessary fast confirmation, only in the past two months I have spent more than $200 in fees for a handful of txs.

Therefore, what I had to do is.. I had to find a way to use cryptocurrencies while allowing me to pay a cheaper price for my payments. In other words, I still have my BTC but they're kinda useless besides moving money without caring whether they're going to be confirmed today or within a month.

I've moved to alts, at least until the mempool unclogs. This is something I've never had to do before. The main issue I see is.. my partners have started asking me for altcoin addresses as well. They're moving off BTC too. The storage size requirement for full nodes is quite high for the average person to afford running one.

With large billion-dollar companies investing in BTC and trying to turn it into a mainstream adoption, the network is only bound to continue clogging up. If that isn't enough, remember that billion-dollar companies can afford even exceedingly-high fees for their transactions. This means that the more companies join in, the less average Joes will afford to compete with them in fees since my $10/tx in fees is nothing for a Tesla-like brand. Putting it another way, this means the billionaires will continue to be able to use the network while your transactions might not get confirmed even within a week.

I'm in this situation right now. I have over 10 payments that I've sent with a previously decent fee (6-8sat/vbyte) that haven't been confirmed although it's been about two weeks ever since they've been broadcasted.

I'm still a Bitcoin fan - don't get me wrong. In fact, I'd absolutely love to be able to continue with BTC. But between having to pay under $0.1 and $15/tx (with only 1-2 inputs!) in fees, I'd obviously choose the former. Hence, especially since I do not consider myself to be living under poor (or under average) financial conditions, I really think people will be soon starting to steer away from BTC in favor of altcoins. The bad news if this happens? Even shitcoins might get more attention..

The even worse news: unless we change this, the network might make a lot of free space for corporations while we might have to move away. What we've once wanted to do, decentralizing the economy, will only be a possibility for the rich.

Therefore, as the title says.. with a clogged network, current (or future) Bitcoin users will start leaving Bitcoin for alts. Change my mind.
3  Bitcoin / Development & Technical Discussion / Are you running Bitcoin Core through Tor? Should it be a requirement? on: March 05, 2021, 10:06:04 AM
As we know, we have the option to run Bitcoin Core either through the clearnet or through Tor. For me, Tor is a must. As long as it improves my privacy, it's an option I definitely wouldn't skip.

However, some people would rather run it through the clearnet. Are you running it through Tor? Why? (If your answer is negative, why not?) Do you have a specific reason?

Also, do you believe it would be better if Bitcoin Core required Tor?
4  Bitcoin / Bitcoin Technical Support / Which scenario is safer than the other? on: February 26, 2021, 04:29:11 PM
You've met some random dude to purchase BTC from him. The dude sends you a transaction with a theoretically high-enough mining fee rate, but even after 2 hours of waiting it still isn't confirmed. He's desperately waiting for the tx to be confirmed so that you can give him the cash.. but the network happens to be congested, so now things become uncertain.

Here are two scenarios:
 1. The transaction he sent you is RBF-enabled. He supposedly has an unfortunate emergency and leaves as soon as you receive the first confirmation on the blockchain
 2. The transaction he sent you is non-RBF. He supposedly has an unfortunate emergency and leaves although the transaction has 0 confirmations on the blockchain

You are quite new to the crypto space so you give him the money anyway thinking it's enough.

Which of the two scenarios are now more likely to turn into a scam?
5  Bitcoin / Bitcoin Discussion / Elon Musk: "Bitcoin is almost as bs as fiat money" on: February 20, 2021, 10:25:54 PM
After so many pumps sparked by Elon Musk through his tweets, Musk calls Bitcoin "almost as BS as fiat money".

He had "Bitcoin" on his Twitter bio recently. His company just invested $1.5B in BTC. He sparked bull runs for a memecoin and called crypto the future currency of Earth - why would Musk back off the Bitcoin bullish mindset and call Bitcoin BS?

The tweet:
Quote
To be clear, I am *not* an investor, I am an engineer. I don’t even own any publicly traded stock besides Tesla.
However, when fiat currency has negative real interest, only a fool wouldn’t look elsewhere.
Bitcoin is almost as bs as fiat money. The key word is “almost”.

6  Bitcoin / Development & Technical Discussion / Storing the seed. Is this method efficient enough? on: February 18, 2021, 10:27:25 PM
I'm planning to store 3 copies of my seed in 3 different locations, but I am not sure if my method is good enough.

My plan is to use an RNG to randomize the order of my seed's words. Afterwards, I'd note down the correct order in numbers and then I'll have 6 different locations: 3 for the randomized seed and 3 for the correct order.

Example:
SEED: answer real swallow drink verify road anger note mountain giraffe cloth fish
RANDOMIZED SEED: real swallow verify answer drink anger fish mountain giraffe cloth road note
CORRECT ORDER: 4; 1; 2; 5; 3; 11; 6; 12; 8; 9; 10; 7

I would store 3 copies of the RANDOMIZED SEED in 3 different places and 3 copies of the CORRECT ORDER in 3 different places as well.

How safe is this?
7  Bitcoin / Bitcoin Discussion / Dubai's IBC Group makes largest investment in Bitcoin's history on: February 17, 2021, 09:15:25 AM
After Tesla, Microstrategy, BNY Mellon, MasterCard, PayPal, Morgan Stanley and many other corporations, it seems like the domino ride has only just begun.

Recently, it has been announced that Dubai's IBC Group is pledging 100k BTC (yes, $5,120,000,000 at the current price) in order to set up a Blockchain Strategy Foundation and other Joint Venture Projects. Here's a little read from Yahoo! News:

Quote
Dubai’s IBC Group Pledges 100,000 Bitcoin, the Largest Bitcoin Investment in History, to Support Setup of the Miami 2.0 Blockchain Strategy Foundation

Khurram Shroff, the Chairman of Dubai's IBC Group, [..] has pledged 100,000 Bitcoin (current value of USD $4.8 Billion) to set up the Miami 2.0 Blockchain Strategy Foundation and many other related Joint Venture Projects. Mr. Shroff's backing of Miami 2.0 Blockchain Strategy could turbo-charge use of the cryptocurrency, which is estimated to transact USD $200 Billion per day, by the end of 2021.

The pledge by IBC group, the largest in Bitcoin history, will be significant in facilitating the digital-currencies adoption across multiple industries and critical in aiding Miami's vision to integrate Bitcoin in everyday transactions.

[..]

IBC Group was recently approached by landmark U.S based real-estate developer Burkhan World Investment LLC to increase the adoption of the blockchain technology in Real Estate and to enable efficiencies in government and private sectors. "Making the largest Bitcoin investment in history is proof of our commitment to assisting cities adopt Blockchain, which we see as the key to enabling widespread adoption," reiterated Khurram Shroff.

[..]

"Enabling investment into Real Estate utilizing Bitcoin as a collateral asset will further enhance its use case as a tool to create a hybrid investment vehicle for BTC holders," said Shahal Khan, Burkhan's CEO and Founder, "Economical debt coupled with a favorable hedge for BTC holders in stable long-term assets such as Real Estate, are a double win for digital currency holders as well as developers and property owners."

Inspired by Miami's Mayor Francis Suarez's commitment to blockchain, both IBC group and Burkhan are looking forward to being a part of Miami's strategic tech vision. In a recent interview, while talking about integrating bitcoin into certain government transactions, Mayor Suarez said, "Cities like Miami, we're trying to attract tech town. It's part of a larger play to position Miami as one of the most tech-forward cities in the country."

[..]

IBC Group has always commended the government of Dubai in leading the world with its Blockchain strategy. It believes that Miami can align itself with Dubai and become the first city to completely run on blockchain in the United States.

8  Alternate cryptocurrencies / Altcoin Discussion / Planning to buy a coin due to a celebrity's tweet? Stop. You're doing it wrong. on: February 16, 2021, 10:02:49 PM
Now that we have a quite thick flow of new users, I think it's time to talk about the way celebrities manipulate cryptocurrency investors (especially newbies!) to put their money into a specific coin.

Back in December 2020, Elon Musk posted a tweet that reads: "One word: Doge". As simple and pathetic as it sounds, the tweet sparked a never-seen-before Dogecoin bullish ride.

- Am I late to invest in Dogecoin?

I am not the best financial advisor so don't take my advice for granted, but I think this is a late and very risky move to make.

On the charts, it looks insane. One who's missed the investment opportunity may think that a lot of people have become rich in the last few months.. but the reality is very different to what the graphs show.

In reality, most of the people who've bought have actually done it only recently. They've done it after the market went bullish. In other words, most DOGE investors that are now still in the markets are late investors still hoping for another bullish run to begin. But if you have not joined the bullish ride before it began, you are likely on a loss right now.

Why?

We are humans. We feel emotions and, for most of us, emotion almost always overtakes instinct. With that being said, when you take a look at an impressive graph such as DOGE's, you might get the fear of missing out.

If you've missed out on a cryptocurrency bull run, you're likely not going to catch up the Train of the Rich again but be left behind instead. And if you try to catch it, what you're doing is.. you're helping the Rich get rid of their bags, making their train more lightweight and hence faster while you, on the other hand, are going to get heavier. Once a cryptocurrency goes through an ATH, expect the richest bagholders to sell their bags. Whenever they do that, they don't care about helping the coin's price increase anymore. All they care about now is redeeming their own wealth, by dumping their holdings onto potential buyers like you.

- But it was Elon Musk who mentioned DOGE.. it should be a good investment!

No. Just because a celebrity posted a tweet in which they mention a specific cryptocurrency does not make it worth more than it used to be. However, smarter and more experienced investors know how to take advantage of this situation in which you are emotionally weak.

Once Musk tweets, the majority of his supporters will likely immediately go over crypto exchanges and purchase the coin he supposedly supports. But there is one thing we apparently forget: Musk could be holding some DOGE himself, so what tweeting its name truly does is.. it allows Musk to multiply his fortune through 3-word tweets.

The ending of these scenarios are usually quite dramatic. Before Musk started doing this with DOGE, back in 2017 another celebrity has done the same. The results? A lot of people have invested in the currencies he promoted, and whoever has been holding these currencies ever since has lost a ton of money.

On the 17th of December 2017, McAfee tweeted about Monero, Verge and Zcash, naming them cryptocurrencies that "cannot lose". Immediately afterwards, Verge had a massive price surge. Three years later, Verge is still in a struggle: it's more than 14 times lower than its ATH, it is currently sitting on the 104th rank on CoinMarketCap and it's been through a number of 51% attacks, the most recent one being.. yesterday!

- So what do I do? How do I get rich?

Trust me - if any of us knew the recipe for getting rich, we'd either keep it for ourselves or everyone would know it. But I am quite sure there is no specific recipe. You need to think your investments thoroughly and smartly.

Ask yourself: what will DOGE ever truly serve as? Because the most common answer is.. it's a meme. Do you really see a future where the world adopts a meme as a daily-driven currency? So.. does it really have a future? That is for you to decide on your own.

The main point is, ask questions yourself and seek the answers for those you don't have one yet. Critical thinking is the key when it comes to analyzing whether a choice or an investment is worth it or not - and think logically: a celebrity is not a crystal ball and they certainly aren't someone willing to make you rich.

10  Local / Română (Romanian) / KYC este periculos si nefolositor.. insa Monero rezolva acest lucru partial. on: February 09, 2021, 09:09:09 AM
Know-Your-Customer este acum cunoscut de multi drept un proces foarte periculos prin care trebuie sa trecem pentru a primi drepturi pe un numar deloc nesemnificativ de platforme care au legatura cu criptomonedele. Cu toate ca s-a dovedit de nenumarate ori ca motivul initial al legii KYC de a lupta impotriva activitatilor ilegale financiare s-a transformat foarte lin in intentii mult mai malitioase, o mare parte dintre utilizatorii crypto par fie ca ignora acest lucru, fie ca pur si simplu nu le pasa de faptul ca, prin completarea formularelor KYC, identitatea lor acum se afla sub amenintarea continua a furtului, vanzarilor de pe piata neagra si spargerilor bazelor de date.

Internetul nici nu iarta, nici nu uita. Iar daca acest lucru nu suna suficient de terifiant, Bitcoin si aproape orice alta criptomoneda cu un registru permanent a carui istorie este prezervata atata timp cat moneda exista este mult mai neiertatoare decat orice altceva am avut de cand exista tehnologia.

Cu toate acestea, oamenii inca tind sa foloseasca platforme centralizate care necesita completarea KYC dintr-o varietate de motive. Comisioanele si ratele sunt mai bune pe exchange-urile centralizate decat ceea ce ofera ATM-urile. Procesul de cumparare este mult mai simplu si mai prietenos cu utilizatorii. Sentimentul de siguranta din moment ce pentru orice click gresit exista Suport Clienti la care poti apela. Astazi vom analiza cum blockchain-ul privat Monero elimina partial riscurile si pericolele reprezentate de procesul Know-Your-Customer.



Uneltele de crestere a intimitatii pentru BTC sunt predispuse la greseli ale utilizatorului si, daca vor fi vreodata exploatate si descifrate, toti utilizatorii anteriori vor fi afectati. Daca exista un motiv specific pentru care imi este teama sa imi cheltuiesc o parte din bani pe servicii precum mixere si CoinJoin, este faptul ca as putea fie sa fac o greseala care elimina efectul acestui tip de servicii fie ca, intr-o zi in viitor, autoritatile sau cineva cu suficient IQ sau noroc ar putea gasi o metoda de a lega intrarile CoinJoin (inputs) de iesiri (outputs) sau monedele mixate de identitatea ta.

Chiar si cu existenta CoinJoin, algoritmi foarte sofisticati inca ar putea sa analizeze monede si sa faca legaturi pe care creierul uman nu le poate face. Odata ce treci monede prin mixer sau CoinJoin, va trebui sa ai grija sa nu folosesti monedele netrecute prin aceste servicii impreuna cu cele trecute. O greseala foarte simpla dar costisitoare pe care o poti face este realizand aceasta legatura folosind resturi (change). Functia Coin Control poate rezolva asta. Insa cati oameni stiu sa foloseasca adecvat Coin Control?

Daca Bitcoin inca are cateva cai de a iti creste intimitatea, toate celelalte monede practic nu prea au. In timp ce poti trece Bitcoinii tai prin mixere, nu poti face acelasi lucru cu Ethereum, DOGE sau Litecoin. Bitcoin se afla undeva la granita dintre ceea ce ofera aproape orice alta moneda si ceea ce ofera Monero din punct de vedere al intimitatii.

Acest lucru fiind spus, unele servicii sau softuri pentru Bitcoin ofera o alternativa potential exploatabila a intimitatii in timp ce alte cryptomonede sunt predispuse la analiza euristica prin care se fac legaturi intre monede si identitati. Intre timp, Monero soseste cu intimitatea implicita si ca focus principal.

Folosind Monero, platformele pe care ti-ai verificat identitatea nu vor sti nimic despre trecutul tau financiar in afara de sumele depuse si retrase din platforma respectiva. Acesta este un lucru care m-a inspaimantat intr-un mod special in trecut: prin analiza euristica, uneltele de analiza blockchain pot afla de unde vin banii tai si unde se duc fara a iti mai cere permisiunea sau declaratia. Din moment ce majoritatea criptomonedelor au registru public si sunt doar pseudonime, este aproape ca si cum bancnotele tale lasa in urma lor o dara sclipicioasa oricand mergi la un magazin, la o banca sau oriunde altundeva.

Bancile stiu cat depui si retragi. Cu toate acestea, daca retragi banii in portofelul tau fizic, lantul de supraveghere se rupe si orice faci in continuare cu bancnotele tale nu mai este treaba lor. Din moment ce registrul Monero este privat, el rezolva aceasta problema devenind versiunea digitala a retragerii numerarului: retrage XMR in portofelul personal si nimeni nu va sti ce se intampla cu el mai departe.

Supravegherea Statului este chiar aici - si Monero poate lupta cu asta. In ultimii ani de zile, reglementarile cryptomomedelor au adus o cantitate numeroasa de legi cu intentii malitioase. De la Know-Your-Customer pana in ziua de azi, cum s-au schimbat lucrurile?

Autoritatile inca se chinuie sa lupte teoretic cu un inamic invizibil si supra-exagerat: activitatea financiara ilegala. Sub aceste trei cuvinte, o cantitate mare de legi au fost trecute prin care intimitatea devine din ce in ce mai putin semnificativa. Daca inainte au reglementat exchange-uri, azi incearca sa reglementeze decentralizarea. Incercand sa puna limite asupra portofelelor negazduite, FINCEN mi-a confirmat gandurile din trecut: conform gandirii lor, intimitatea ar trebui sa fie o crima.

Cu toate astea, Monero soseste ca o solutie si pentru aceasta problema. Portofelul monedei nu poate fi reglementat din moment ce nu exista o evidenta publica pentru autoritati prin care sa verifice daca adresa si sumele declarate "se pupa" cu ceea ce scrie in registrul public sau nu.



Asadar, prin Monero, KYC si alte legi similare (sau chiar mai rele) acum reprezinta un risc mult mai mic decat cel reprezentat de monedele cu registre publice. Spunand asta, odata cu trecerea timpului si transformarea tot mai puternica a tarilor in "Surveillance States" camuflate in libertate si democratii, putem lupta cu asta si putem incerca macar sa ne recapatam intimitatea.

Nota: postarea aceasta nu se intentioneaza a fi o contradictie a thread-ului lui @1miau ci o solutie pentru cateva riscuri si efecte pe termen lung generate de KYC si alte legi similare.
11  Economy / Economics / What are the potential side effects of corporations selling fake crypto? on: February 08, 2021, 08:29:52 PM
PayPal has started selling "crypto" but they don't let you withdraw. Hence, if you think about it, they could easily only literally sell numbers on a screen rather than a math-backed, miner-verified real cryptocurrency.

I was wondering what could happen from an economical point of view if they (or any other corporation) did this and suddenly wanted to manipulate markets using false coins. What could PayPal do to BTC?
12  Alternate cryptocurrencies / Altcoin Discussion / KYC is dangerous and useless.. but Monero partially solves that. on: February 07, 2021, 10:06:05 AM
Know-Your-Customer is now known by many of us as one very dangerous process we have to go through in order to be granted rights on a not-insignificant amount of cryptocurrency-related platforms. Although it has been proven over and over that its initial intention to fight illicit financial activity has smoothly turned for the most part into a much more malicious intent, a large part of cryptocurrency users seem to either ignore this fact or simply not care that, by completing KYC forms, their identity is now situated under a continuous threat of theft, black market sales and database hacks.

The internet does not forgive, nor does it forget. And if this does not sound scary enough, Bitcoin and about any other cryptocurrency with an immutable ledger that is historically preserved as long as the coin exists is more unforgivable and unforgettable than anything else we ever had since technology.

However, people still tend to use centralized platforms that require KYC completion due to a variety of reasons. Fees and rates are better on centralized exchanges than ATMs provide. The purchasing process is way simpler and more user friendly. The feeling of safety since for any click going wrong there is a Customer Service to call. Today we are going to analyze how Monero's private blockchain partially eliminates the dangers and risks posed by the Know-Your-Customer process.



BTC's privacy-enhancing tools are prone to user mistakes and, if ever broken/exploited, every single previous user will be affected. If there is a particular reason I am afraid to spend part of my money on services such as mixers and CoinJoins, it's the fact that I can either commit a mistake that eliminates the actual effect of those kind of services or, someday in the future, authorities or someone with enough IQ or luck could find a way to link CoinJoin inputs to outputs or mixed coins to your identity.

Even with CoinJoin's existence, very sophisticated algorithms could still analyze coins and make links a strong human brain can not. Once you mix or join coins, you will have to take care not to use non-privacy-enhanced coins together with privacy-enhanced ones. One very simple but costly mistake you can make is creating this link using change. Coin Control could solve that. But how many people know how to properly use Coin Control?

If Bitcoin still has some ways to enhance your privacy, all other coins pretty much don't. While you can mix your Bitcoins, you cannot mix your Ethereum, DOGE or Litecoin. Bitcoin is situated in between what pretty much any other coin and Monero offers from a privacy point of view.

With that being said, some Bitcoin services or software do still offer a potentially exploitable privacy alternative while the rest of cryptocurrencies are  prone to heuristical analysis that link coins to identities. Meanwhile, Monero comes with privacy as a default and main focus.

By using Monero, platforms you have verified your account on will now not know anything about your financial past besides how much you have deposited and how much you have withdrawn. This is something that has particularly frightened me before: through heuristical analysis, blockchain-analyzing tools could find out where your money came from and where it's going without even asking for your permission or statement. Since most cryptocurrencies are fully public and pseudonymous, it's almost like your banknotes leave a glittery trail behind whenever you go to a store, bank or anywhere else.

Banks know how much you deposit and withdraw. However, if you withdraw cash to your physical wallet, the chain of surveillance breaks down and whatever you do with your banknotes is none of their business anymore. Since Monero's ledger is private, it solves this issue by becoming the digital version of withdrawing cash: withdraw XMR to your private wallet and nobody knows what happens to it anymore.

Surveillance States are here - and Monero can fight that. In the past few years, cryptocurrency regulations brought upon a numerous amount of maliciously-intended laws. From Know-Your-Customer 'till this day, how did things change?

If anything, authorities are still supposedly strongly fighting an invisible, overly-exaggerated enemy: illicit financial activity. Under these three words, a large number of laws have been passed through which privacy becomes less and less meaningful. If before we had them regulate exchanges, today they are trying to regulate decentralization. By trying to limit unhosted wallets, FINCEN has proven my previous thoughts right: according to their mindset, privacy should be a crime.

However, Monero comes as a solution to this as well. Its wallet cannot truly be regulated since there is no public evidence for authorities to verify whether your declared addresses and values fit what the public ledger has stored or not.



Therefore, with Monero, KYC and other similar (and even worse) laws now pose a much smaller threat than they pose with public ledgers. Having said that, as time goes on and our governments plan how to better turn our countries into Surveillance States while still camouflaging it better than ever before in an only apparent freedom and democracy, we can fight this all and try gathering our privacy back.

Disclaimer: this is not supposed to be an argument against @1miau's thread but rather a solution to some of the risks and long-term effects of KYC and similar laws.
13  Bitcoin / Electrum / Improving privacy with light wallets (SPV) on: February 05, 2021, 10:46:46 PM
As far as I know, when you're using Electrum in SPV move you're asking some servers to retrieve your addresses' balance.

I was wondering whether there was an option for Electrum to send false requests to those servers so that you confuse it about the addresses you truly own.. is there any way to enhance your privacy through it?

I'm looking for either this or using a new Tor route/identity for each balance request so that address balances never get requested from the same IP. The main principle is the same: I'm looking for a way I could use Electrum with Tor without telling a certain server which addresses I truly own..
14  Alternate cryptocurrencies / Altcoin Discussion / Privacy coins. How much do you think we need them? on: February 03, 2021, 11:17:19 PM
We are living in an era of technology. Our entire present is digitalised day by day as we move on to a new normal where online is more prominent and important than the offline world.

Education has moved to the Internet, something that would've been considered a negative influence over children only one year ago. Things have changed quite drastically, although it happened so smooth we already got used to our new way of living.

As we move on with the digitalization, Bitcoin becomes more and more used. However, a considerable amount of people choose Bitcoin to enhance their financial privacy. Considering Bitcoin is not a private blockchain, tools like Chainalysis owns are a threat against a significant part of Bitcoin's users since the largest part of them do not use coin control and consolidate outputs and dust the wrong way, revealing their historical traces.

In consequence, the existence of privacy-focused coins might come in handy in the era where surveillance and control are on an All-Time High. On the other hand though, that is not the case for everyone - especially since investors are being pushed away as cryptocurrencies like Monero are slowly being delisted from exchanges while privacy slowly becomes a crime.

So I wanted to gather a general opinion on the subject. What do you think? In the current times we're living, are Monero and privacy-focused coins a necessity?
15  Alternate cryptocurrencies / Service Discussion (Altcoins) / Ledger and Service Error 503. Intentional or overload? on: January 29, 2021, 04:15:25 PM
I've been watching Dogecoin in the past 24h continuously, but made no move on the market for many hours straight. But then, I decided to finally make a move and sell the remaining coins I had in my Ledger Nano S.

Binance suspended DOGE deposits. RobinHood went crazy as well, but believe it or not.. they both go crazy whenever DOGE goes wild as well. Binance finally unsuspends the deposits and I decide to make my move. I go over Ledger Live and try to send my DOGE, but I meet the Service Error 503 message every single time I try to spend my coins.

Cryptocurrencies are supposed to be decentralized. But the fact that multiple platforms suspended their service with DOGE specifically or turned into sudden errors makes me believe it's a plan between them all to manipulate markets.

Been around 9 hours and I still cannot spend my DOGE through Live. This is what Ledger has turned into: weak database security, adding centralized exchanges to the user-friendly Ledger Live and now suddenly DOGE goes into "Service Error" once prices go wild.

Fuck Ledger. I'm moving out all my coins ASAP and might start supporting an actually decentralized hardware wallet, not something that centralizes what's supposed to be free.

EDIT:
2 API rate errors, 15 DOGE downtimes in under 24h and still counting. See the errors and downtimes here: https://status.ledger.com/
16  Alternate cryptocurrencies / Marketplace (Altcoins) / [H] BTC; [W] 11 XMR on: January 26, 2021, 08:01:48 AM
Looking to purchase up to 11 XMR.
The minimum trade amount I accept is 0.01 BTC (or 2.5 XMR).
BTC/XMR rate will be taken from CoinMarketCap at the time of trading.

Will go first if I trust the person I'm trading with.
If you aren't trusted, you will have to either go first or use escrow. For the latter, you will be covering the fees.

BTC transactional fees will be covered by me if you agree with 5sat/byte or less. Otherwise, they will be deducted from the BTC sum you receive.
17  Alternate cryptocurrencies / Altcoin Discussion / Is there a way I can use a single seed for all my cryptocurrencies? on: January 06, 2021, 11:33:31 PM
So Ledger gives us the ability to use a single 24-word seed for all cryptocurrencies you'd like to hold, which is quite convenient. However, I've been having some trust issues with Ledger lately and the Secure Element (and having to plug an USB device every time I want to make a new tx) makes me feel even more insecure.

I currently have all my crypto holdings anonymized through mixers, Tor, coinjoins, Whonix etc so that all links to my identity are broken; my computers are all running fully free operating systems.. so plugging in a device with a non-open-source component, especially since the device is specifically created for crypto transactions, might be a mistake privacy-wise.

Now I have a few other cryptocurrencies I'm holding besides BTC but I was wondering if there was a way to have only a single seed for all those coins besides Ian Coleman's tool. I have so many papers with a different seed on each for every coin, which becomes quite annoying at one point.. so I thought if there was a way to replicate what Ledger's done with the 24-word seed, it'd be so much easier to use the same one for all my coins.

Any ideas?
18  Bitcoin / Wallet software / JoinMarket with already pruned node on: December 27, 2020, 10:30:08 AM
I've been using JoinMarket on a full node for a while but I'm planning to switch to a smaller, less power-consuming device which doesn't have enough storage space to hold a full Bitcoin node on it. It's synced right now, but it's pruned. How can I set up JM to work with an already-existing ".dat" file rather than creating its own so that I don't have to resync the blockchain from zero?

So right now if you wanted to run a full node, you'd have to sync the entire blockchain from its inception, back when addresses were all empty. This uses a lot of storage and makes syncing take way too long for an average PC.

But I was just wondering: as long as the blocks are accepted by the majority of nodes/miners, what is the need of having so many hundreds of thousands of blocks stored? If nodes accept and successfully verify the last.. say 100 blocks, then why is it necessary to also store the other n-100 (where n = number of mined blocks since Bitcoin's inception)?

I understand that syncing from zero and preserving the entire blockchain makes it pretty impossible for history to be manipulated. But wouldn't it make more sense to basically snapshot all the current balances of addresses and start over from there, storing only the last 100 blocks and, every time the 101st block is mined, to store the 1st mined block as a now-permanent, verified change of the addresses' balance and then the wallet would remove it from the device, now basically considering the newly mined block (the 101st) as being the 100th and so on?
20  Alternate cryptocurrencies / Marketplace (Altcoins) / [H] BTC ; [W] 1500 BEAM on: December 08, 2020, 01:49:36 PM
Looking to purchase up to 1,500 BEAM.
The minimum trade amount I accept is 0.002 BTC (or 150 BEAM).
BTC/BEAM rate will be taken from CoinMarketCap at the time of trading.

Will go first if I trust the person I'm trading with.
If you aren't trusted, you will have to either go first or use escrow. For the latter, you will be covering the fees.
