[146號檔案] Steem價格與獎勵?

最近Steem價格波動很大,讓我對於一個老問題又感興趣了起來。這是一個我一直有疑問,卻一直找不到答案的問題。

簡單說是這樣,當Steem價格下跌時,帖子收入下降,這沒問題,天經地義。

但我一直認為,如果點讚情況沒有太大變化,那麼我們所收到的SP,以及Curation的獎勵,應該不會有太大變化才是啊!邏輯很簡單,Steem跌了,這些以Steem為支付形式的獎勵,本身價值就會下跌,如果Steem數量還下降的話,那不就是加速降低了?不太合邏輯啊~~

所謂的加速降低就是:Steem跌價10%,作者們收入卻下降遠高於10%。這就很奇怪了。

所以呢,今日我就用146檔案來做做練習題好了。試試看能不能解出什麼來….

geometry-1044090_640.jpg

假設Steem總量是1000萬顆,市價是$10,假設SBD精準錨定$1。

假設每天新增萬分之一,1000顆Steem,是要分配給作者的(先忽略curation獎勵)。故當前每日之獎勵池則為1000*$10 = $10,000。

假設某熱門作者能固定獲得總點讚量的1%獎勵,因此,每日可獲得 $10,0001% = $100 的獎勵。獎勵一半是SP,一半是SBD,所以,支付形式為 5 SP ($50/$10) 與 *50 SBD ($50/$1)。

進一步分析這一獎勵支付的SBD部分:1 SBD其實是用 0.1 Steem打包而成的(此一概念從bitshares的錨定貨幣就是這樣的,不知道的請自己學習一下),所以,50 SBD其實就是 5 Steem。

因此,總支付其實是 5 SP與 5 Steem,可以說就是 10顆Steem,與每日新增1000顆Steem的1%相同!很好,再次驗證正確性。

好,現在,讓Steem價格腰斬,下降至$5。

每日新增貨幣量不變為1000顆,但獎勵池的現金價值變為 $5,000。仍假設該作者獲得的總點讚數比重不變為1%,則其獎勵將變為 $50,支付形式為 5 SP ($25/$5) 以及 25 SBD ($25/$1)。

結論:Steem價格下降,Post payout顯示值會下降,但給付的SP不會改變,只是價值下跌


進一步推論一:

如果以上場景考慮Curation,其實就是再撥出一些不用轉成SBD的Steem,發給Curators。基本推論應該一樣,則Curation獎勵應該也不會下降。

進一步推論二:

如果考慮SBD的溢價問題,甚至完全不影響上述推論,只影響其實最後拿到SBD的作者,其實收入更高。故基本推論也不變。


以上對於Steem價格與獎勵之間的關係,做出基本的分析。可喜在於,我的想法似乎在這計算下是對的。

可是…. 可是….

嗚嗚嗚~~~ 這還是跟我過去的經驗感覺不符啊!原本我想或許我邏輯推論哪裡有錯,最好是這一個練習題可以指出我的錯誤,然後我終於大概知道為何我錯了。可是沒發生啊!

到底真相是什麼啊!!??

還好這是一四六檔案,不以真相為目標,一切都是草稿,腦內風暴,不知所云….

只盼這些,能夠激起智者,而能回答我的問題,那就阿彌陀佛了!


[146號檔案],我們下次見!

1 提醒下次還會是146號,不會變成147號。不懂的請問隔壁同學。

Radar Relay: Trustless Token Trading on Ethereum.

Hi traders, Dan (@tradealert) and Dean (@deanliu) are back for our weekly feature and today we’d like to show you how to trade on Radar Relay.

5339f07a6da811b11ff4bf5e-750-563.jpg

Radar Relay.

A while back we posted a review of the 0x Protocol in which we mentioned a few decentralized exchanges (DEX) among them Radar Relay which we’d like to talk about in more details today. We’ll start with explaining the benefits of trading on this exchange (I), then we’ll show you how to trade tokens (II) and finally how to hedge your position in a bearish market (III).

I-Benefits of trading on Radar RElay.

  • Radar Relay (RR) is an 0x-based DEX (D0x) which allows you to trade ERC-20 tokens and Ether directly from your LEDGER or MetaMask wallet;

  • Because your crypto never leaves your wallet, you are always protected against counter-party risks (hacks, phishing,etc);

  • You can trade on RR for no fees until the 1.0 version goes live, the fees will then be denominated in ZRX tokens;

  • You can broadcast orders through social medias using the carrier feature:

https://www.youtube.com/watch?v=Q41HM5U483g

II-Trading Ether and ERC-20 Tokens from a LEDGER.

  • First make sure to have Ether in your LEDGER (you’ll need it to trade on RR) and that the ETH app is turned on with Contract Data and Browser support enabled;

  • Go to Radar Relay and open the App;

  • Once in the App, follow these steps:

DQmWtBqs3B7siu4JMyw8M8BcAHgkrz4K3218N7NNr637poo_1680x8400.png

RR first need to convert (wrap) the ETH you want to trade with into WETH (WrappedETH), both wrapping ETH (3.) and enabling trading with WETH (2.) will cost you a very small transaction fee (around 2 Gwei) which you need to confirm manually on your Ledger.

  • Now you can use your WETH to trade tokens as you would in a normal exchange:

5.PNG

  • Close your trade by unwrapping leftover WETH… and that’s it, you can close the app, your new tokens are awaiting in your LEDGER.

As you can see all these operations are conducted directly from your secure hardware wallet without exposing your ETH to counterparty risk, user experience is very smooth and is only going to get better as the 0x team has announced the near release of a trading widget which will abstract away the need to wrap ETH.

III- Hedging into DAI.

DAI is a stable coin which trades on Radar Relay. Just like Tether, DAI is transferable, pegged to the dollar and can be redeemed for USD on some exchanges.

Unlike Tether though, DAI tokens are backed by Ethereum collaterals (and soon gold) and their supply is transparently managed and auditable on the blockchain which makes it a much safer hedge than Tether in our opinion.

If you’d like to know more about how DAI works under the hood, we recommend you watch this fantastic interview with Rune Christensen, the founder of the Dai project.

  • DAI tokens can be purchased on RR for WETH as you would for any other token:

2.PNG

For example, hedging your ETH from your wallet would look something like this:

ETH>(wrap)>WETH>(trade)>DAI>(trade)>WETH>(unwrap)>ETH

  • DAI can also be traded directly for other ERC-20 tokens;

4.PNG

  • A word of caution though, liquidity with DAI/ parings (that includes WETH) is still very thin so it’s recommended you check the spread carefully before you buy so you don’t lose money on slippage.

And that’s it for today guys, as you can see trading on RR is a breeze, the exchange truly is a wonderful piece of engineering which will give you a taste of the power of 0x-built exchanges and a glimpse into the future of what decentralized exchanges on the Ethereum network can become.

Cheers.

💯 什麼叫專業素養,這就是了。

警告:如果正在吃東西,請停止動作後再看文章,以免發生危險!


我要說一個很好笑的被詐騙經驗 (別擔心,沒成功)。這件事發生在兩週前了吧,我一直留著一些screenshots,都忘了發。上次,看到 @fr3eze的這一篇文章,跟我的經歷非常相似喔!基本上都是:Telegram+早早辨識出壞人+抱著好奇心情玩弄一下。這件事我後來轉述給我老婆聽時她笑到肚子疼,算是詐騙者無意間的無量功德吧!

由於我當時犯了一個錯誤:當你report一個telegram用戶為SPAM後,你們之間的對話紀錄將會馬上消失。所以,我沒能來得及留下一些我以為事後可再複製的對話畫面,這部分就用口述的。好啦,說說看,看你覺得好不好笑囉~~

話說,當時我逛到一個似乎是叫做CryptoHunt的ICO,大概是加密貨幣的Pokemon之類的項目(內容不重要啦),所以我就加入了他們的官方Telegram群去瞧瞧熱鬧。話說,一加入後不久,馬上就有個David Dooley的用戶給我PM私訊,問我有什麼投資方面的問題。我一開始還沒意識到有問題,因為印象中有些群是會這樣的(不過似乎都是自動BOT而非真人?),我反正就去群裡看了一下,想說,喔,真的耶,David Dooley是admin,或許不是來騙人的。然後…


這位假David說沒兩句我就知道有詐了,總之你只要覺得過分熱心多半是假的。但是你看看,這位假David可是全套都裝成真David了!我去查過群裡的真David,兩者只差在username:假的是David Dooliey,多一個小小的 i。其實我很想告訴他,用大寫I去取代小寫 l 就天衣無縫了。你看看我示範:@ David_DooIey。像不像?實在不夠專業。LOL

在這裡很慎重地提醒各位一件很重要的事:

Telegram是很ICO常用的社群管道,但Telegram上很神奇的是,所有你的公開訊息,包括帳號!!統統都是可以一直改的!!

這一點,我一直不懂,允許帳號可以改的邏輯是什麼。再加上你可以自由複製別人的頭像與簡介,代表你幾乎可以完全模仿另外一個你看到的Telegram帳戶(請看魔鬼終結者第二集,謝謝)。

當然啦,還有些小地方是可以參考鑑別:例如真David會顯示跟我有一個共同群,而假David沒有。


我確認之後,就一方面跟假David假意詢問有沒有bounty之類的問題,另一方面就去通知那官方群裡的真David。於是你看到左邊這樣的圖,有兩個David。上面的真的,從頭到尾沒理我,可能是太忙了,後來讀了我給他的警告訊息,也沒說聲謝謝,所以我原本要投1,000顆ETH,決定就算了。

然後我就跟假David繼續玩玩,看看你們這些人渣都是怎麼玩的。反正這跟現實世界的詐騙不太一樣,他頂多知道我TG帳號,還能對我怎麼樣呢?(沒辦法用我電話叫一堆Pizza)


總之,他對於一些非關投資的問題,都說會去問團隊什麼的,但對於投資就很積極。說他幫我爭取了限時優惠,有50%的Bonus等等,很正常啦,算是蠻典型的騙子,哈哈哈。我跟他說要投多少我忘記了,沒有很誇張,還說我要時間去籌錢,問他期限多久,他只說盡快。其實那時候我腦中,只想著要怎麼玩他,想到我自己笑得樂不可支。

我先透露一下我當時的計畫:我心想,你可以變身,我也可以啊!大家都一樣的。好啊!那我也來變身David Dooley,然後再上來跟你說我籌到錢了,是不是很好笑啊?兩個人都長一樣,然後都是假的David,只是我這個假David是為了要去玩弄另一個想騙我錢的假David而變的,真的David要是知道,肯定是要笑死了吧!?

所以,我還是先去練習了一下變身,順便瞭解一下這個小技巧,說不定以後謀生會用上咩 增廣見聞啦!變身完我自己都快笑死了~~ 你們當時要是在Telegram看到我肯定不認得我的。


看吧!這就是後來變身的我!我還特地取名叫做 “尋找雙胞胎兄弟”,哈哈!

我記得我是第二天才把這件事搞定,開始了我的捉弄計畫。


沒想到,竟然,更令我意外的事發生了….

是的!就像你所看到的,我的計劃失敗了。原因是,

David已經變身為別人了!
David已經變身為別人了!!
David已經變身為別人了!!!

David現在叫做Fred Fooks,臉也變了,難道是我認錯人了?

當然不!!很簡單啊,他同時要騙好幾個項目啊!川劇變臉算什麼!?Telegram變臉才賺的多嘛!

你看看對話記錄都還在的,就是這傢伙啊!Fred Fooks!不不不,是David Fooley,不不不,他誰都不是啦!!都是工作所需啦!LOL… 快笑死我了!


正當你以為,對方會意識到被抓包,要不然就是不理我了,要不然就是罵我是瘋子,等等。不然呢?還能怎麼樣?

你錯了!

真實人生,永遠比戲劇更戲劇!

這位當時是Fred的假David,看到我丟訊息質問他是誰之後,不慌不忙地,發揮了他們充分的專業素養,請我等一下。

然後,他就變回David了 ….
他就變回David了 ….
他就變回David了 ….

囧囧囧囧囧囧囧囧!!!!!

你看看左圖,他把頭套套回去了,名字還沒改好。然後,繼續當作什麼事都沒發生的,問我是不是要轉錢了,然後繼續把以太地址給貼上來。服務一如既往的一貫貼心,也沒生氣,也不緊張。


在那一刻,我覺得我長大了好多。

從我現年25.5歲,長大成為32.8歲那樣的老了。

服!得服!專業就是專業,做什麼事情都要敬業,才能成功。

我後來還說要對方該吃藥了,他依然沒有動怒,還說如果投資我們的話,請再通知我們喔….

寫到這裡,我很後悔沒有投資這麼專業的詐騙人士了。

我最後的嘲諷,其實只暴露出我只是一個25.5歲的,年輕唔知,不懂世事的毛頭小鬼罷了。

Be advised that ICO isn't really Initial Coin Offering.

If you are quite familiar with how ICO works, skip this post. This isn’t written for you.

If you are new (some would say late) to this crazy cryptocurrency party and do not understand how these activities around the blockchain project crowdfunding work, then I hope this reminder can serve as a little notice for you when you try to invest your own money into a seemingly ambitious and visionary new project with enthusiasm.

This message is actually quite simple …

ICO isn’t really Initial Coin Offering.


What I mean is that ICO isn’t really “Initial” Coin Offering, at least with most cases nowadays. A general practice for ICO is to first get some invited investment first, they can be PE, can be VC or even some celebrity who is going to endorse the project later. Then, there will be a pre-sale, which means if you can afford to invest a lot then you might be able to buy the tokens first with a cheaper rate before the general crowds swarm in.

So, only after all those above fund raising activities are executed, then comes the ICO, which is of course not initial in any ways!! Even you are an early participant in the ICO and hence get a good bonus rate, you are at best at the 3rd or 4th or 5th… coin offering.

This mistake actually comes from the fact that ICO gets its name from IPO - Initial Public Offering, illogically. People whoever invented this term replace the adjective Public with a noun Coin and the error was made. So ICO should really be Initial (Public) Coin Offering, just like IPO is actually Initial Public (Stock) Offering. Omitting the word Stock is reasonable because there isn’t hardly anything similar that can do a public offering (yeah, when cryptocurrencies were not born yet), but omitting the word Public is actually quite a bad choice as later ICO/Token-crowdfunding evolves to be offered several times before it goes public.

ICO actually sounds more prestigious than it really is. You, as an early ordinary investor, should not be confused that before you, who deliberately mark your calendar to participate the first magical bonus hour(s) to send your BTC/ETH in the middle of the night, get to buy these magical tokens, they have been offered several times to others already.

[隨筆] 海洋

又是一波低潮。前方也許還更低。

stone-sanho-3023521_640.jpg

其實並不是特別低,只是相對於過去半年的熱鬧歡愉。

到這裡來,不知道已經過去幾個寒暑,人情的寒暑,只怕多於實際的寒暑了…

回想以往,這裡的朋友圈總是一波一波的,一陣帶滿浮游生物的浪潮打來,帶來許多新小魚,大夥兒在浪頭上,開心互相介紹,談論來自四海八洋的訊息~~ 好不熱鬧~~

浪總是會過去,逐漸在浪下行的過程裡,吃了一點海藻,或是想吃卻吃不到海藻的魚兒們,紛紛離開,或是切換至靜音自動導航模式,海洋又安靜了起來…

這是一個現實的海洋,我愛它的真實,它的真實就是現實。

如果你游泳到這裡來,偶然地,遇見了,我們,這些早一點,也是游過來的魚群,因為有浮游生物吃,所以在這裡駐足玩耍,直到遇見了你,餵你吃點海草,不自私地說聲,一起玩吧!

如果你留下來了,玩耍了,吃了點心了,當然也不要忘記,我們都是為了食物而來的,當食物枯竭時,彼此都有可能,轉身離去。到時候,如果,沒有道別,就此消失,也請不要,錯怪無情。

人情,需要有現實的支撐,在紛紛擾擾的岸上,在虛幻無邊的海洋,道理一樣,亙古彌新。

在這一個藍色海洋裡,食物支撐了人情,沒有了戲台,再精采的戲也無法續演。

感恩多的,不錯怪不應有的,才是你快樂悠游的智慧之道。

或許我的智慧還不夠,還是會偶爾想起,N-1 N-2 N-3 … 波的,被浪花掏盡的老小魚兒們。也許他們此刻,正在新發現的美味海洋裡,開著狂歡的海神派對。
