1901  Bitcoin / Hardware wallets / Re: My dad got a Ledger from Best Buy.... on: December 09, 2022, 12:12:20 AM
By local retail store do you mean official resellers?  I think they have enough resellers to cover most parts of the world.  If planning to buy a Hardware Wallet physically with Cash, just plan the next vacation in a city where an official reseller can be visited.
Some countries only have one or two resellers at the moment, so it can be a problem if you can't make a trip. In my case, I need to travel for at least half a day to buy from them. They do support online shopping but you'll need to give some personal info at one point or another. Makes me wonder if they share the data with Ledger or not.

Another problem is the price, buying locally costs a lot in my area, probably because the reseller wants more profits. The price difference can start from 30 to 50%. It is probably not a problem if something like Nano S is your target though. I just wish it can be even cheaper.
1902  Bitcoin / Hardware wallets / Re: Are my coins too safe? on: December 08, 2022, 11:52:54 PM
Satoshilabs have been giving more widespread awareness to the passphrase feature, which could lead to some people who are not advanced yet with management of their wallet to commit a mistake.
I think anyone who wants to use something like this or prepare their inheritance should learn and be aware of this in the first place. Like it or not, it is their responsibility to learn and manage their wallets if they want to be in control. If they are not comfortable with it, then their only option is to trust a third party to make sure their family can access their crypto in the future, which is probably not the best choice.

With time, I think more and more people will get accustomed to it, just like people are familiar with 2FA or other layers of protection that currently exist. If you think about it, a password or 2FA can also be a problem for you if you forget or misplaced it, so the key is how to make sure you can access it in the future.

I just check the app, I will copy some of their UI some stuff looks much better. Their free indicators and just Closing Price, Price Change %, Volume, and Japanese Candlestick Patterns I can't use this at least I need RSI.
Thank you for the link Smiley
Oops, my bad. I didn't see the detail on the right page about the premium plan. Quite expensive if you don't trade regularly for $6 a month imo, but there is a discount right now so you can buy it for around $4. Yeah, it definitely has a good UI, you can use it as your inspiration.

I search further and found another website that can be your inspiration/competitor, it needs registration but it is free according to their faq (https://altfins.com/alerts/notifications). Looks like it supports RSI too. It has an IOS app, however, based on the feedback from the users it is terrible. It needs some rework so you have to use the website if you don't want any problems.
1904  Alternate cryptocurrencies / Altcoin Discussion / Re: Alert to Trust Wallet users: There's an ongoing address spam, be more cautious. on: December 08, 2022, 12:27:30 AM
Just in case everyone is not aware yet, this is not exclusive to Trust wallet, for example:
https://bitcointalk.org/index.php?topic=5425022.0
https://bitcointalk.org/index.php?topic=5425735.0

Looks like the attacker has been doing this for a few days now, but the victims just recently post more on social media. Personally, I got these spam transactions months ago, not exactly identical but share some similarities. I wonder if the attacker is the same person/group or not. He definitely targets wallets that allow users to copy and paste addresses from the transaction history easily. A feature like that allows him to hide some characters to trick the user, but unfortunately, even those who use other apps or HW also fall for this trick.

Looks like we need to check the whole address just to be sure we don't get tricked next time. Using the bookmark/contact feature on your wallet might be a good idea so you don't have to copy-paste every time you make new transactions.

Here's were things get interesting, for sometime now each USDT transaction he execute on his Truth wallet app, he usually gets some sort of reward (less than cents) either in TRX or USDT. But unknowing to him that was a spam attack and not reward from trust wallet as he thought.
Sounds very similar to what happened in one of those threads I linked above. Is there any reason why he assume it was a reward though? I don't recall Trust Wallet having any promotion like that.
1905  Economy / Trading Discussion / Re: App for crypto indicators on: December 07, 2022, 09:37:33 PM
Have you tried this app[1]? This sounds like what you need. I never use this though so I can't give a detailed review, looking at their website and demo you can see that it gives you multiple alerts based on technical formation and it supports many coins/exchanges at the same time. It has a paid version but the free one should be more than enough for your needs. You might want to check it out and use it to improve your own apps if you don't trust them.

I am using TabTrader but it has an alert only for the price(I am not familiar with how the pro version works) so that is not enough for me.
As far as I can remember, yes, they only have a price alert. They do support many indicators but you need to monitor them yourself when you trade. It is definitely not the right tool for your needs OP.

1906  Economy / Service Discussion / Re: Apple blocks Coinbase wallet release on IOS on: December 07, 2022, 09:20:56 PM
Atleast someone has to voice about this so users may realize what they are going through unless the rate of control will further progress with years and every update.
I'm pretty sure there are tons of complaints about their policy on social media, but their users will keep buying or using their product since there is no alternative for them and they are too lazy to move to another ecosystem. Apple has no incentive to change either since people still buy their product, so it's kinda useless.

If Apple continues to do all these, they may also be blocking the rest of the wallets on iOS. Trust Wallet could be his real target.
How big is Trust Wallet market share on IOS? They are smaller than Coinbase on the app store, with fewer downloads and user ratings too. I doubt they want to kill such a 'small' wallet when they already went for the bigger one. Cash App is probably the next target if there is really some sinister idea behind this move.

I didn't know existence of AltStore which don't need jailbreak. Although requiring computer for initial setup would discourage many average user who're used with convenience.
If they are considering using an alternative app store, I think most of them would be prepared to do something more than just download and install an app. At least that's how I feel when I regularly mod my Android phone in the past. But doing this on IOS is definitely not easy, not many apps are supported by default and we need to find our own IPA files to sideload. CMIIW.
1907  Bitcoin / Project Development / Re: Changing Google Captcha to Biometric Scan | Extended application to Crypto walle on: December 07, 2022, 07:37:54 AM
My biggest concern is privacy and security. How can we ensure that my fingerprint data is secured? If I understood your idea correctly then somebody can link my activities and probably figure out who I am as long as they get my fingerprint scan data. What if some malware is installed on my phone and use the data to log in to our sensitive account for example?

I can understand why phones or other devices use fingerprints as their locking mechanism since the data is stored offline (assuming they don't send it to some server of course), but using fingerprints as a captcha for online service sounds like a bad idea. Compared to captchas that exist right now, using fingerprint or other biometric verification sounds like a step-down. At least if we consider privacy as something really important for the user.

Btw, you also mention a crypto wallet as the target for this, I think we can separate captcha and wallet verification entirely since their goal is different. Fingerprint for your crypto wallet can work with fewer privacy issues (if your wallet is a cold wallet at least), and you don't need to connect to the internet to do that in the first place. If you want to use your device as an extra security, you might want to install FIDO (or buy one like Yubico) or something similar, so you don't need personal data for that too. CMIIW.
1908  Bitcoin / Hardware wallets / Re: Ledger Stax (Ledger's latest hardware wallet) on: December 07, 2022, 07:00:59 AM
This is such a weird product. They claimed it was designed to travel wherever the user goes, but why would they bring an HW wallet when traveling in the first place? Or is there a new trend where people get a cold wallet when they take a trip? Bringing a hot wallet like a phone is probably the better choice, no need to carry two devices just to manage your crypto. I can see understand if it is like an NFC card or something similar like that. Since it is cheap and doesn't attract unwarranted attention, unlike this one.

Looking at how they promote this wallet, looks like their target is new retail investors who usually hold crypto on exchanges. Maybe one or two of their research department staff look at Reddit and see that this thing can sell since those people like fancy stuff, it is clearly not for me (and probably not for the majority of the user in this forum either). The price is also insane in my region, I can buy 3-4 Nano S for one of these, which is a better deal.
1909  Bitcoin / Bitcoin Discussion / Re: Are end-stage adopters going to be happy owning fractional amounts of bitcoin? on: December 07, 2022, 06:08:33 AM
Not sure about that statistic, maybe it's a bit logical to calculate the number of privatekeys that have been generated through wallets.
I'm pretty sure this is just a hypothetical scenario from OP, you can replace the number with 1 billion or 40 billion, the point is the number of users who uses Bitcoin is way larger than now and most of them probably don't own 1 BTC or even 0.1 BTC.

Are end stage adopters going to be happy/proud/satisfied/well-off owning a few million satoshis? Will end-stage adopters own only thousands of satoshis? Mabey by that point people will disassociate the value of bitcoin:fiat and associate it to another form of value?
If Bitcoin is as mainstream as you imagined it to be, I think most of us will be happy even if we don't own 0.1 BTC. There's no need to feel shame just because you own a thousand satoshis if they are worth millions. I don't think we will see fiat die completely and be replaced with other currencies, so I think BTC:fiat won't be gone either. However, I can see BTC being used as the standard instead since fiat is inflationary and so prone to failure (like Bolivar, for example). No reason not to be happy if that is the case.
1910  Bitcoin / Bitcoin Discussion / Re: Can Bitcoin Destroy Crap Altcoins? on: December 07, 2022, 05:56:21 AM
I'm pretty sure altcoins will stay for a while. A lot of companies and corporations are trying to gain some market share from this and I don't think all of them are useless. You don't even need Bitcoin to crush those shitty altcoins since coins like Ethereum, Monero, etc are definitely going to outlive them. I expect there will be more cases like FTX, Celcius, etc in the future. The market will continue to filter shitty companies that promise 20% annual return as the only way to keep their business afloat. It's like what mk said, most of the altcoins are moving to their own category and do not compete directly with BTC.

What are your views on the future? I clearly know that the persistence of beliefs is often not so strong, and few people can hold Bitcoin for a long time.
We got a nice cycle if you take a look at the past. A bull market comes, lots of companies get mainstream, and shortly after that they go bust after the bear market starts, some revive with another name, etc. You will be surprised to see that a lot of users are holding BTC for years, and the number of 1 BTC holders is increasing every year. BTC will definitely stay, while scam/shit tokens will die sooner or later.
1911  Local / Trading dan Spekulasi / Re: [DISKUSI] Harga Bitcoin on: December 06, 2022, 09:19:39 PM
Jika 2023 harga Bitcoin bisa meningkat 3x dari harga saat ini, maka ATH baru akan segera datang.
2024 mungkin maksudnya ya gan? 2023 dan 2022, kalau berdasarkan pengalaman beberpa tahun ke belakang adalah masa bear market dan sideways berkepanjangan di mana market lesu dan banyak retail investor yang exit dari pasar, untuk kemudian masuk lagi di tahun berikutnya. Masih banyak kok yang berharap atau prediksi Bitcon balik lagi ke level 10k, jadi jangan kaget kalau harga Bitcoin terjun ke bawah lagi di setahun ke depan. Kalau agan ingat, di bear market sebelumnya kita sempat nyentuh 3k lagi loh.

Saya tahu, ada banyak whale diluar sana, tapi sepertinya juga masih kesulitan untuk memompa harga BTC hingga ke $500K.
Setidaknya framework para pemain besar (pemerintah, investor gede dst) buat 'mengontrol' Bitcoin dan kripto sudah semakin mantap, mungkin harga di atas $100k bukan hal yang muluk beberapa tahun ke depan, dan setelah itu bakal stabil di harga tersebut supaya mereka bisa meraup profit sebelum siklus dimulai lagi. Setidaknya itu sih yang ada di kepala ane, walau basis teknikalnya hampir tidak ada. Tahun lalu ane sempat percaya BTC bisa nembus 100k kalau dilihat dari pola rainbow, ternyata pola itu malah direvisi tahun ini, jadi kita lihat saja. Masih percaya Bitcoin bakal nembus ATH baru sih, timing dan berapanya itu yang ane ga punya jawabannya.
1912  Local / Bahasa Indonesia (Indonesian) / Re: [INFO] Informasi Phishing, Malware, Virus Dst (WAJIB BACA) on: December 06, 2022, 09:02:04 PM
Kalau menurut saya sih zaman hari gini, kalau istri, saudara, kerabat dekat yang agak agak gaptek mending jangan diinstalin aplikasi mbangking biar ketika dapat phising kayak gitu hackernya kena apk not found atau via sms ya?
Agak ekstrim juga sih gan kalau sampai mereka dilarang (apalagi kalau mereka sering pakai), paling tepat ya edukasi plus dikasih info kalau scam kaya gini sering terjadi dan mereka harus tanya agan dulu sebelum instal/download/klik apapun yang aneh". Bisa juga pasang app yang bisa filter siapa sender/caller yang nelpon ke hp agan, walau hal ini juga berisiko membuka privasi keluarga agan sebenarnya. Ane biasanya bilang ke keluarga kalau ada kebutuhan penting nunggu sms dari nomor yang terdaftar saja, jangan langsung terima telpon aneh". Walau banyak yang ga pakai kripto banyak juga spam kripto yang masuk ke nomor mereka.

Alternatifnya pake HP jadul saja biar mereka memanfaatkan sms banking, walau kebanyakan keluarga ane biasanya lebih memilih datang langsung ke bank/ATM kalau ada kebutuhan, jadi aplikasi mbanking dan sejenisnya malah ga kepakai.

ya sebenarnya gak juga orang IT pun paham kalau pesan itu mau nipu, karena ngirim poto yang seharusnya file .jpg, png atau jpeg tapi ngirim .apk
Jangan kaget dengan kegaptekan orang gan, apalagi kalau mereka cuma sering lihat/follow berita di sosmed. Kadang malah jadi salah paham, dikira instal .apk terlepas dari sumber apapun adalah virus. Keluarga ane banyak yang gaptek dan tiap ada pesan bermedia sering langsung diklik tanpa diperiksa dulu itu file apaan. Beruntung ga kena spam sejenis yang dishare agan dewo di atas.
1913  Local / Topik Lainnya / Re: Cara Membuka situs Binance dan Reddit tanpa VPN di android, pc, linuk dan ios on: December 06, 2022, 08:17:54 PM
maksuddku itu DNS, karena pada threadku ini - https://bitcointalk.org/index.php?topic=5386649.0 banyak debat soal dns itu dilarang pemakaian sehingga akun rawan diban sehingga kemungkinna akan hilang balance di sanna
Setelah ane baca cepat, sepertinya sudut pandangnya lebih ke ISP agan ngeblokir situs" tertentu jadi agan mengakali dengan menggunakan DNS, sementara IP agan masih tetap transparan ke situs yang bersangkutan, dalam thread ini Binance. Jadi pemakaian resolver cloudflare yang agan gunakan hanya membuat ISP agan tidak bisa mendekripsi request situs apa yang agan akses, tapi Binance bisa menyediakan jasanya ke agan dengan normal karena IP agan masih tetap IP Indonesia dan Indonesia tidak masuk dalam list blokir Binance, malah sebaliknya Binance yang diblokir aksesnya oleh pemerintah Indo (ane belum update terkait izin PSE, mungkin sudah berubah sekarang).

Dulu pada tahun 2014 pernahh kubaca pemerintahh pernah melarang menggunakan dns google, sehingga pennggunaannya tidak memblokir situs apa pun. https://www.cnnindonesia.com/teknologi/20141008125322-192-5719/pengguna-internet-dilarang-pakai-dns-google
Sampai sekarang ane rasa masih ada efeknya karena kalau agan mengubah DNS di pengaturan jaringan Windows biasanya tidak berefek langsung mengingat ISP pada pake transparent DNS. Tapi balik lagi ini lebih ke ISP itu sendiri dan bukan situs yang agan akses. Tapi memang ga ada salahnya nanya dulu atau cek faq apakah penggunaan DNS itu boleh atau tidak. Dari pengalaman sejauh ini sih, rata" yang tidak diperbolehkan adalah yang membuat IP pengguna berubah karena hal ini bersangkutan dengan regulasi dan hukum, sementara enkripsi request DNS biasanya tidak membatasi akun agan. Kecuali exchange juga kerjasama dengan pengguna untuk memblokir siapa saja yang memiliki IP Indo.
1914  Local / Altcoins (Bahasa Indonesia) / Re: [SHARING] Scam Berbasis Smart Contract, Bagikan Di Sini! on: December 06, 2022, 08:02:41 PM
Yang mengerikan adalah authorizeApproval(), kita tau, saat kita akan melakukan transaksi , kita butuh approval, namun si scammer bisa menemukan celah tersebut. karena yang dikirimkan oleh scammer token eksis yang sudah diapprove secar sadar oleh user, jadi wallet pengirim tidak butuh approval token lagi, ia hanya butuh approval pengiriman.
Ane masih agak bingung dengan bagian ini. Dari hasil bacaan ane, yang ane pahami adalah fungsi" token ini dipanggil oleh si penyerang secara remote, tanpa ada input dari user. Pemanfaatan fungsi transferfrom ini juga digunakan untuk menghasilkan error supaya transfer token dengan nilai 0 usd ini bisa dilakukan, jadi kalau misalnya ane ga pernah transaksi USDT, ane nangkepnya masih bisa jalan.

Ane mendapatkan pemahaman ini dari penjelasan bagian ini:
The _approve() function also excludes the full zero address and modifies the authorization value. The focus of this function is in the parameter calculation of the transferFrom call to approve, which uses_allowances[sender][_msgSender()].sub(amount, "BEP20: transfer amount exceeds allowance") , to subtract the number of existing authorization tokens from the transfer The remaining authorization amount is put into approve and re-authorized. The subtraction function sub() used here is OpenZeppelin's safemath library, and overflow will report an error revert; however, if the parameter amount of the whole process is zero, no detection mechanism can reject the transaction, which also leads to a large number of $0 transfers on the chain that can be sent normally, and the hacker only needs to pay a fee to reap a significant return.

Sepertinya metode scam ini cukup berhasil, banyak korban ane lihat di beberapa hari terakhir bikin thread sampai mengira ini bug di jaringan ETH/BSC. Mungkin perubahan di metode penolakan transaksi bisa membantu menghentikan model serangan ini, selain kewaspadaan user tentunya. Ref selain beberapa thread di atas:

1915  Local / Altcoins (Bahasa Indonesia) / Re: Negara Inggris Minta Data Pengguna Binance on: December 06, 2022, 07:41:52 PM
itu pasti akan menjadi sebuah hype dan merusak pamor dari exchange tersebut.
Agak aneh juga sih kalau pemerintah berusaha untuk melindungi nama baik exchange (kecuali mereka punya kepentingan, misalnya ada saham di situ), mengingat semakin banyak exchange dengan sistem buruk yang keluar dari bisnis harusnya semakin baik (contoh FTX dsm lebih baik cepat berhenti beroperasi karena dana user gagal dilindungi dengan baik. Tapi alasan detailnya ya bisa saja untuk proses investigasi butuh kerahasiaan supaya pelaku yang bersangkutan tidak bisa mempersiapkan diri karena dia tahu pemerintah sedang mencari informasi tentang dirinya, atau mungkin lainnya.

Btw di thread global ane lihat banyak user yang bilang Binance minta data KYC ulang dengan foto wajah plus bukti alamat rumah mereka, khususnya mereka yang berdomisili di EU. Kurang jelas ini perubahan karena aturan yang mana tapi Binance mengklaim kalau peraturan regulasi terbaru membuat mereka harus melakukan hal tersebut. Paling baru sih ane lihat berkaitan dengan MICA: https://www.consilium.europa.eu/en/press/press-releases/2022/06/30/digital-finance-agreement-reached-on-european-crypto-assets-regulation-mica/

Untuk user Indo ane rasa belum ada perubahan, tapi siap" saja kalau misalnya agan diminta KYC ulang. Ane pribadi merasa kurang nyaman kalau harus mengungkap sedetail mungkin, mengingat banyak kasus data leak terjadi dan menyebabkan banyak doxing ke user yang bersangkutan.

jika nominal yang di curi senilai lebih $10 juta maka sudah pasti pencuri tersebut bukanlah orang bodoh, dia pasti sudah menggunakan mixer untuk menghilangkan jejak nya. meminta data pengguna ke CEX seperti binance dan lainnya bakal sia sia
Orang pintar juga bisa membuat kesalahan gan. Ga ada salahnya mencoba mencari data sebanyak mungkin tentang user tersebut toh itu termasuk kewajiban mereka. Malah bisa dikritik kalau mereka ga meminta data padahal tahu kalau user punya akun di exchange A atau B.
1916  Economy / Exchanges / Re: Kucoin future trading on: December 05, 2022, 12:54:06 AM
Well if you're sure about that then asking for their support is probably the only way to go. Looks like there are no other users of Kucoin futures posting around here. Try asking on their Telegram or social media maybe, they are more active here. If this is indeed the expected behavior maybe you should try other platforms, asking for more than 10% per trade is quite ridiculous imo.
1917  Bitcoin / Development & Technical Discussion / Re: Is it cool to run Bitcoin full node on Android OS? on: December 04, 2022, 12:26:15 AM
I think some Android mods such as the advanced charging controller Magisk module allow you to bypass charging so your battery doesn't die too quickly. It needs a custom kernel though, and if your phone doesn't have a custom ROM it is probably not gonna work. Might be able to reduce the wear on the battery if anyone is interested in doing this, but yea I'd rather buy a Pi or a cheap laptop instead.

1919  Bitcoin / Bitcoin Discussion / Re: Who has/had the oldest mined Bitcoin? on: December 03, 2022, 12:49:39 AM
I mean, technically speaking satoshi (and maybe Hal) has the oldest mined Bitcoin in this forum. The exact number of addresses they owned is unknown, I won't be surprised if they spread their holding over several addresses and never move it again due to various reasons. Even if they are still active here, I don't think they want to get unnecessary attention by posting their addresses OP.
1920  Economy / Exchanges / Re: Kucoin future trading on: December 03, 2022, 12:35:02 AM
Their tutorial doesn't really make it clear either, but I don't think that's supposed to happen. If you take a look at https://www.kucoin.com/futures/refer/baseBTCPosition, the position opened with a slightly lower fund so there might be some fees at play, but I doubt it would eat more than 20% of your initial fund. Better call for support and clarify it I guess.
