今天比特币终于突破了12万大关。比我预测的晚了半个月。不过也还算不错。我依然保持着年底20万的信息。
今天比特币跌到9万,以太坊3000,怎么办?
这轮一直拿比特币的挣到钱了,拿其它币的都没怎么挣钱。
以太坊3000,总市值不过3000多亿,我觉得谈不上高估,所以一个都不卖。

这轮要是就这么个行情,庄家好像也挣不到钱啊?
2  Bitcoin / Hardware wallets / Re: Hackers sent email that Trezor database has been hacked hacked on: November 09, 2025, 01:16:56 AM
I am a Trezor user and received the following content via email. However, upon checking the Trezor official website, I found no corresponding content.

Quantum Computing Notice

Dear Trezor User,
     Recent breakthroughs by Google and IBM in quantum computing have fundamentally altered the security timeline for cryptocurrency wallets. Quantum systems now exceeding 1,000 qubits with improved error correction have compressed what was a 10-15 year threat window to an estimated 6-12 months. The ECDSA cryptography protecting your assets is mathematically vulnerable to these quantum computational methods.
We've developed a firmware release in collaboration with MIT, Stanford, and NIST cryptographers. This implements post-quantum lattice-based algorithms proven to resist both classical and quantum attacks. Installation takes 4 minutes via Trezor Suite and doesn't affect your recovery seed or balances. We strongly recommend updating within 72 hours.

Respectfully,
Trezor Security Engineering

除非老美再次大放水,
不然老美保持当前的高利率,今年想要相对于21年的顶部再翻2倍到18万刀都很吃力。
这么多年,老韭菜,长期投资者,都对BTC充满信仰。对山寨,甚至是ETH,都不放心。
如果拿比特和黄金市值相比,目前比特币(11万美元/枚)是黄金的1/10。如果这轮涨到20万美元/枚,是黄金的1/5。
黄金可是5000年信仰,有各国央行储备,所有人都认可。很难想象比特币还有多少上涨空间。

以太坊目前只有5000亿美元的市值,再涨一倍,也只有1万亿美元。对比英伟达挺有差距的。如果未来能在元宇宙流行,用起来,10年后,考虑到通胀,5-10万亿美元市值可以期待。实在不行,当前这些应用,还是值个5000亿美元的市值。

这轮牛市过后,再抄底,也许 BTC占1/3,ETH占2/3,更合适。未来,赌区块链的应用。

有没有高手讨论下这个问题?

买了一个trezor safe 3,查过是能用USDT的,买回来发现只能用ETH链的U,不支持TRON链。 Cry
试一试Metamask软件钱包连接Trezor safe 3使用,也许可以。

我本身用Electrum和Ledger Nano这两种冷钱包
Ledger 是闭源的,名声不太好。

...请问,这个可以离线签名交易吗?

Electrum软件可以离线签名,可以连接Trezor、Bitbox、Ledger等硬件钱包使用。

对比最近的美国数据,
目前美国股市一天成交量在7400亿,美国财政部存款在5700亿,而央行美联储资产总值在6.7万亿。
此时已经2万亿市值的比特币,靠谁来拉盘?能拉多少?

除非老美再次大放水,
不然老美保持当前的高利率,今年想要相对于21年的顶部再翻2倍到18万刀都很吃力。
all data source came from:https://chainmonitor.xyz/btcCompare
我的判断,如果没有更大的故事,BTC和其它山寨都没啥多大的投资价值了。现在4万亿美元的总值,在翻一翻就是8万亿,全部美股才不到100万亿。
除非区块链还有更大的应用,主要就是元宇宙。赌一把吧,不要把全部家当都投这个(不管是BTC,还是ETH),输了日子正常过。

我以前也投资过以太坊而且我投资的金额也不算小, 可是握了好几年也不见什么盈利, 以太坊价格的涨幅比起比特币实在是太少了, 最后我也没什么耐性继续持有以太坊了. 我在不亏损的情况下, 把所有的以太坊都卖了. 之后, 我决定只专注于投资比特币就好, 比特币始终是加密货币的王者, 这点是无可置疑的.
今天是2025.2.12,ETH/BTC已经跌倒了0.0272,从2024.5换仓到ETH,到目前BTC涨了60%,ETH还跌了10%。不经历这些,很难体会你当时的心情。这说明了一个问题,投资组合里BTC不能少于一半。
我依然坚持:
(1)目前加密货币的应用情况(如果不能在元宇宙里起飞),很难支持BTC再高飞了。因为BTC市值2万亿美元,而黄金不过10万亿美元,美股也不到100万亿美元。如果BTC再涨2-3倍,那就是5万亿美元,还能再高到哪里去?但万一大家都发现没什么投资价值时,跌起来就恐怖了。
(2)如果加密货币还有投资价值,肯定是AI导致大规模失业后,巨量的经济和就业转向元宇宙。而加密货币在元宇宙里扮演重要角色,这些是前提。如果不相信这些,不如本轮结束就离场。
(3)币安广场有博主说Sol收入已经超过ETH 十倍了,但仔细算算,这一年的收入也就总市值1%的水平,投机的成分还非常浓。当然,普通人也说不清楚,ETH会不会被Sol取代。我只知道前面10年,主要的创新来源于ETH。BTC并不适合做大规模应用,但它协议简单,适合做元宇宙的黄金。而ETH可能是元宇宙里的石油。
鉴于应用链的不确定性,下一轮,投资组合应该是:50% BTC,50% 大概率还是ETH。

望高手指教,多谢!

以太坊/比特币汇率,在过去2轮周期,都是在熊市底部开始反弹几个月,至高位后(本轮达到0.088),连续振荡下跌几年(本轮恐怕已经超过3年下跌了)。目前已经是0.033,简直被骂成一坨屎。
幸好我不需要买房买车,不急着挣钱。这一轮,随便庄家怎么玩,我是不会再换仓了。
我依然坚信以太坊能到1万刀,坚守中......

下一轮,如果元宇宙还遥远,还是应该只专注比特币,直到比特币突破前高1.3倍以后(预计离狂牛半年左右了),再考虑换仓。更保险。超前一步,盆满钵满!超前三步,尸骨无存!

...It would make it safer to use that way, but I just never liked Metamask wallet and I don't care much about ethereum and all it's tokens, but Rabby.io wallet  is much better eth alternative for metamask.
...
The metamask mobile app is extremely stuck and basically unusable. The chrome web extension can be used normally. But when connecting to keystone, the QR code of keystone cannot be scanned. Maybe it's because I used a poor quality USB camera(Nominal resolution 4K, but very cheap), and replaced it with a laptop camera and it worked fine.

According to the data I found, Trezor currently has 150 employees, while both onekey and keystone only have 30+ respectively. The open-source hardware wallet companies are too small.

全仓梭哈猛干这种投资策略太刺激太极端了, 我确实没有那种胆量全仓梭哈, 但是比特币突破10万美金时, 我几乎把我所有的比特币都清仓了, 赚了不少钱, 现在就耐心等待比特币价格回落, 再重新开始建仓。
你是老手,牛逼!
作为一个只有3年经验的新手,我从2022年开始抄底比特币BTC,一直买买买,最后一次是在4.4万刀加了一点,后面一直持有到2024年5月全仓换了以太坊。我一直是全仓,从未下车。
回顾总结,我觉得有两点需改进:(1)应当留1/3比特币仓位,今年以太坊在2100-2500刀振荡了3个月,很打击信心;
                                           (2)换仓太早,应当在BTC/ETH汇率下降到历史高点(0.088)一半,再减10%,也就是0.04左右换仓。或者等比特币突破8-9万刀,再换仓。
下一步的工作,是等待卖出时机了。这轮,以太坊怎么着破8000刀值得期待,边走边看!
兄弟们,一起努力,发财!

今天已经突破8万了。我相信这一轮的牛市会持续到2025年中下旬。也许明年达到10万的时候主流媒体大量关注才会进入疯牛阶段。牛市高点猜测会在15万-30万区间吧。
但是我想不出这轮牛市结束后会下跌到多少。
可惜这把我满手的以太。大饼兑换以太后,到目前依然汇率亏损20%。...只玩比特,下轮4-5倍足矣。
耐心点,eth会追上来的,等大饼到顶了,以太还会充一波,最终以太的回报率还是会比大饼高。跟需要耐心和信念。
昨晚上BTC突破了10万刀,ETH看似表现还可以。前段时间牛逼哄哄的Sol,最近安静了,市值被BNB和XRP超过。看来,山寨王还是ETH,很稳!


这一波牛市来得真的是太快太猛了, 我真后悔美国大选之前没有全仓买进比特币, 我只买入了一点比特币, 如果我敢全仓买进比特币, 我想今年买辆蓝宝坚尼的梦想绝对能实现, 现在又错过了这波大牛市行情, 并且比特币的价格也飘的太高了, 我真的没有追高买入的勇气, 现在只好静观其变了.
兄弟,你全仓了没?梭哈干,不要怕。
12  Bitcoin / Hardware wallets / Re: Onekey Classic or Bitbox on: December 04, 2024, 02:59:56 PM
Now keystone passed the open source testing of WalletScrutiny, but onekey still not.  (see https://walletscrutiny.com/hardware/keystone3.pro/ )
Maybe because OneKey code was not tested for a long time by them, and they are not always up to date.
I see OneKey Touch was check last time 1 year ago, and OneKey also discontinued some old devices and released new models.
Now they have OneKeyPro and OneKey Classic 1S that was never tested by Walletscrutiny website.

See https://walletscrutiny.com/hardware/onekey/   and  https://github.com/OneKeyHQ/firmware/releases (I have check the hash of classic.3.9.0-Stable-0805-f3b0717.signed.bin)
The latest version of classic/v3.9.0 (Aug 12, 2024) still not passed through WalletScrutiny's testing.   
Why can a hardware wallet that has never passed walletscrutiny testing be called an open-source wallet?
13  Bitcoin / Hardware wallets / Re: AirGapped Hardware Wallets on: November 26, 2024, 03:31:41 PM
       The benefit of using a USB connection is that every time you connect your Trezor device to your computer, it will undergo a firmware hash check. See https://trezor.io/learn/a/trezor-firmware-hash-check
The advantage of keystone is that its screen is large, making it easy to check payment addresses or contracts, and prevent clipboard viruses. It is also difficult for online viruses to infect hardware wallets through QR communications. The disadvantage is that Keystone cannot check the firmware of the hardware wallet and the authenticity of the device online in real time. Therefore, in addition to device authenticity verification, Keystone is also designed a self-destruct function. Its defense focuses on supply-side attacks.
       Is my opinions correctly?
14  Bitcoin / Hardware wallets / Re: Keystone 3 HW coming soon! on: November 22, 2024, 07:28:13 AM
Keystone is the first hardware wallet brand whose Black Friday deals I have come across. There is a 20% discount for all purchases across their shop. To get it, you don't need to enter any discount codes. The Keystone 3 Pro is now $119.20 instead of $149. Use promo code "BFFORX" to get another 10% off. The Keystone 3 Pro will then cost you $107.28. Pretty good deal if you are considering purchasing this hardware wallet.
I cannot purchase directly from the official website, and bought from the Chinese reseller(https://keyst.one/resellers). Today I checked the price and it is only $111 (799 RMB). The reseller was kind to refund me $14 (100 RMB).

I want to buy a Keystone, just for use with Metamask and to store altcoins, like ETH, Sol, USDT, USDC.
Considering that they only communicate through QR codes, and the firmware of Keystone and the Metamask app are both open-source, and come from different companies, wouldn't that make it more secure?
It would make it safer to use that way..
Thanks for your suggestions.

...but I just never liked Metamask wallet and I don't care much about ethereum and all it's tokens, but Rabby.io wallet  is much better eth alternative for metamask.
Watch out for Keystone wallet battery, you have to charge it on regular basis or it could stop working and die, this is the weak spot of new Keystone 3 devices, and it's not easy to replace batteries like in older version.
In the Google Store, Metamask has been downloaded 10 million times, while Rabby has been downloaded 100,000 times.
I may use hardware wallets very rarely, and the battery will die. At that time, it will be charged through a USB cable while using.
15  Bitcoin / Hardware wallets / Re: Keystone 3 HW coming soon! on: November 21, 2024, 12:10:23 AM
Despite Trezor being trustworthy, I don't want to rely solely on it. I have purchased a Keystone 3 Pro, and will store ETH along with my Trezor Safe 3.

That's completely normal, I understand that. It makes sense to spread out your coins and store them in batches using different hardware wallet brands. Too bad that you didn't wait a few more days to purchase your Keystone. Black Friday is coming up. Keystone's website is already advertising Black Friday deals starting from tomorrow. You could have saved some money.
Thanks for your help.  It cost around $137 and just arrived today.
Now I have three hardware wallets, Trezor safe 3, Keystone 3 Pro, and Bitbox02. I use Trezor safe 3 and Keystone 3 Pro with the Metamask software to store altcoins, and use Trezor safe 3 and Bitbox02 with the Electrum software on a offline computer to operate BTC (this is already secure enough, so there's no need to use Electrum's multi-signature function).
16  Bitcoin / Hardware wallets / Re: Keystone 3 HW coming soon! on: November 20, 2024, 01:27:16 PM
... I am sure there are security experts who have vetted Keystone and its products, and you will need to trust that they did a good job. It probably hasn't been put under the miscroscope as close as Trezor, for example...
Despite Trezor being trustworthy, I don't want to rely solely on it. I have purchased a Keystone 3 Pro, and will store ETH along with my Trezor Safe 3. This will help diversify risks. Keystone uses QR codes, which feels more secure than USB.
17  Bitcoin / Hardware wallets / Re: Keystone 3 HW coming soon! on: November 17, 2024, 10:00:11 AM
I would be interested to read that blog post, and I know WalletScrutiny could not verify source code for older version but that was one year ago.
This is not the first time I saw companies from China doing modification on source codes like this.
WalletScrutiny has successfully verified Keystone 3 Pro for six times. Now is it safe enough? See https://walletscrutiny.com/hardware/keystone3.pro/#resultsArchive

I want to buy a Keystone, just for use with Metamask and to store altcoins, like ETH, Sol, USDT, USDC.

事实证明,合约基本99%亏,现货短线90%亏。只有高手适合玩短线。我自觉智商普通,能有碗饭吃就不错的那种!

我以前也投资过以太坊而且我投资的金额也不算小, 可是握了好几年也不见什么盈利, 以太坊价格的涨幅比起比特币实在是太少了, 最后我也没什么耐性继续持有以太坊了. 我在不亏损的情况下, 把所有的以太坊都卖了. 之后, 我决定只专注于投资比特币就好, 比特币始终是加密货币的王者, 这点是无可置疑的.
从24年5月换仓以太,到现在一点没涨,3000点坚如磐石!现在币安广场一群唱衰以太坊的,咒骂的。可能有不少人失去了耐心,已经换仓了。不亲身经历,恐不能理解这种痛苦!

耐心点,eth会追上来的,等大饼到顶了,以太还会充一波,最终以太的回报率还是会比大饼高。跟需要耐心和信念。
币安广场一些专业博主,曾经坚定看好以太,现在动摇了,将以太本轮预期下调至6000。
比特币不管多牛逼,再涨一倍预期到头了。以太总不会6000都到不了吧?唯一山寨ETF,难道那些美帝大财团也看走了眼。
事已至此,我也只能给以太陪葬了。技不如人,听天由命!

不要买太山寨的币,不要玩合约,不玩短线。心越大,死得越快!
