Cybersecurity-företag använder krypterad hårddisk med Bitcoin för att testa sökande

Framgångsrika sökande kan använda medlen för att köpa en biljett till företagets huvudkontor.

Att låsa upp en hårddisk som innehåller krypto

Forskare som vill ansöka till New York-baserade Red Balloon Security måste genomföra en ovanlig teknisk intervju som en del av sin ansökningsprocess: att låsa upp en hårddisk som innehåller krypto.

Enligt en rapport från Business Insider skickar Red Balloon hårddiskarna till vissa kandidater för forskarpositioner inom cybersäkerhet på företaget. Den som har „färdigheterna och passionen“ för att knäcka krypteringen skulle kunna göra anspråk på 0,1333 Bitcoin (BTC), eller ungefär 4 800 dollar vid tidpunkten för publiceringen. Sökande som har tillgång till mynten uppmanas att köpa en biljett till New York City för nästa steg.

„Vi är ett av få företag i världen som gör detta, utanför olika underrättelsetjänster“, säger Ang Balls VD för Red Balloon. „Vi är ett litet företag, vi letar efter en mycket nischad typ av säkerhetsperson och vi har inte den enorma mängden mänsklig energi att slösa bort på screening genom varje enskilt CV.“

Men framgångsgraden var ungefär 1%

Cui sa att cybersäkerhetsföretaget skickade testpaketen till nästan alla sökande, men framgångsgraden var ungefär 1%. Red Balloon har för närvarande 29 anställda, varav 6 enligt uppgift har gått med det senaste året.

Han lade till:

„Om jag skickar ut 150 till 200 pund hårddiskar [med Bitcoin] får jag vanligtvis tillbaka en mänsklig teammedlem. Det är en värdig investering.“

Företaget grundades 2011 och har tydligen tagit denna unika inställning till tekniska intervjuer under en tid. Minst en Crypto Twitter-användare hävdade att de hade fått liknande instruktioner för att hämta Bitcoin för fem år sedan, medan andra påpekade att Red Balloon hade utmanat programmerare att låsa upp hårddiskar med krypto som en del av Defcon-hackarkonferensen 2017:

OK, denna Red Balloon-utmaning är allvarligt cool! Skaffa en hårddisk för att vända Bitcoin från (firmware) lördag vid poolen.

This Wall Street giant is quickly getting rid of Ripple (XRP)… and he doesn’t want to hear about it anymore!

XRP still roughed up – Bad news continues to fall for Ripple Labs and its interbank token. The investment company Grayscale has indeed just taken one more step towards the total withdrawal of XRP from its crypto funds intended for institutions.

Ripple’s XRP abandoned by Grayscale

The company Ripple Labs , issuing the XRP , accumulates trouble since the Securities and Exchange Commission (SEC) has called its interbank token of securities ( securities ).

Among the crypto exchanges and offers offering XRP, Grayscale Investments had already stopped all new subscriptions (and canceled pending ones) for its investment fund Grayscale XRP Trust.

In a new press release shared by OTC Markets, Grayscale now announces that its multi-cryptomonnaies funds – Grayscale Digital Large Cap Fund (GDLC) – contains no more XRP simply.

The decision was made on December 31, 2020. The XRP of this fund were all resold , to be replaced by the 4 other crypto-assets of the Digital Large Cap Fund. Grayscale thus bought more Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC) and Bitcoin Cash (BCH) instead of the Ripple token.

The new composition of this fund (below) also always gives pride of place to bitcoins , which weigh 81.6% on their own, followed by ethers which constitute 15.9% , litecoins and other Bcash supplementing the last remaining percent.

However, XRPs accounted for only a small portion (1.4%) of the GDLC before their (final?) Withdrawal.

With this new defection, Ripple finds himself more and more isolated in the face of the SEC’s accusations. Will Grayscale go so far as to completely dissolve its XRP fund? In any case, this is the very last step that the investment company would have to take, if it wants to get rid of any risk associated with the future of XRP.

Where to find good Bitcoin data?

Do your own research: where to find good bitcoin data?

How can someone interested in Bitcoin glean stories from data? And where can one find useful data? The first steps towards this will be explained in the article.

A motto closely associated with the crypto scene: Don’t trust, verify. Don’t just trust, verify. An attitude that is reflected in the abbreviation DYOR (Do your own research), which is also well-known in the Bitcoin ecosystem. After all, it is not simply about disclosure, but about making every BTC-ECHO reader an empowered crypto-citizen. Therefore, two of the data sources used will be presented in this article. For today, we will focus on Bitcoin.

A word up front: I use the programming language R for the data analysis. If you want to learn more about Bitcoin Machine scam this powerful statistical programming language, you can watch this video. However, all the data sources mentioned in the rest of this video are also accessible with other tools such as Python.

TradingView is well known far beyond the Bitcoin scene. The price analyses on our site are basically carried out using this powerful platform. TradingView is a fantastic platform for creating charts. What few know: A first step to juggling data can be exporting the TradingView data. Thus, TradingView has a quite powerful programming language, Pine, which we introduced in this article.

But what if you want to combine external data with the TradingView data? For this purpose, the platform has been offering the possibility of data export for a few months now. One click makes it possible to export both the Bitcoin rate and all indicators in the layout as a csv file:

CSV files are tables in which all values of a row are separated by commas. This gives you an easy-to-read format that can also be imported into Excel or similar.

The analyst-to-be can now work with this data. In R he would be able to read it in with a simple command:

data <- read.csv(„path/to/filename.csv“).

Of course, there are other possibilities. Many fans of R swear by Tidyverse, a group of libraries for R that makes working with data extremely easy. The Tidyverse is also reflected in particular in the Bitcoin Reports. However, it is beyond the scope of this article to go into more detail.

Juggling with bitcoin price data from Coingecko

One disadvantage of the above approach is that processes cannot be automated. Why work with programming languages if you still have to click three times to process the data further? Here, a more direct access to the courses would be helpful.

For this, the analyst of Bitcoin & Co. is often not simply concerned with prices. The development of supply and market capitalisation is always the focus of the analysis. It is true that TradingView can also help here and the amount of available data is growing. But analysts are dependent on additional data sources in this respect.

In many places, working with programming interfaces, so-called APIs, is a good solution. API stands for Application Programming Interface and, simply put, enables access to data from the command line or from a programme. Coingecko is an example of such a platform with an API. The good thing is: Currently, you don’t have to register for it.
