Yellow Card CEO reminisces about losing his life savings on LocalBitcoins

Early mistakes can mean big losses.

In his college-aged days, Chris Maurice, the CEO of African crypto exchange Yellow Card, said he put his life savings into Bitcoin (BTC), finding it stolen shortly after. 

“Bitcoin was about $200 at the time, and I decided basically I was just going to dump my entire savings account into into it,” Maurice told Cointelegraph in an interview. Maurice said he had approximately $5,000 in his savings back then, with which he bought roughly 21 BTC.

“I was holding it all on LocalBitcoins, because that was the wallet that I used at the time and I didn’t really know any better,” Maurice said, mentioning a popular platform used for over-the-counter, or OTC, Bitcoin transactions. “You would think I would have done a little bit more research before just dumping my life savings into something,” he added jokingly.

Common industry practice warns users against holding much of their crypto storage on custodial exchanges and online wallets, as those options pose greater security risks while giving users less control over their assets. Using two-factor authentication, or 2FA, on these types of accounts is likewise seen as a must for personal security, though Maurice admitted he failed to do this as well.

“Somebody got in and took all of it, except for 0.8 [BTC],” Maurice said. “That 0.8 Bitcoin I held on to until it started spiking and then sold it 16 days before it spiked up from like $1,700 to like $6,000 or whatever,” he added, referencing Bitcoin’s historic year when the asset ultimately rose from less than $1,000, all the way up to almost $20,000. “So I kinda got screwed on both sides of that,” he recalled with a laugh.

In addition to his crypto storage mishap, the CEO also sold Bitcoin on eBay in 2015, and built a small business selling the asset at Taco Bell with his friend Justin Poiroux.

How to Protect Yourself from the Cryptojacking Threat

Republished by Plato

Published

on

Though fairly common in today’s age, for many, Cryptojacking might still be a brand-new term. What is Cryptojacking? Is this a threat for all computer and internet users? How can we prevent falling victim to Cryptojacking? And many more such questions are common. Some of the most common concerns have been addressed below.

What happens in Cryptojacking?

Cryptojacking is the latest, most innovative, shape of cybercrime. These jackers will use your computer to mine cryptocurrencies maliciously. This can happen on both personal and business laptops, computers, and mobile devices. Cybercriminals hack into any of these devices to install software that uses the computer/laptop/smartphone’s resources and power to mine cryptocurrencies or steal wallets of unsuspecting victims. This is a grave threat as it is hard to detect and easy to deploy and run in the background. The main idea is using another computer and device’s resources to do crypto mining work for them and whatever earnings or steals they make from the hijacked computers, they siphon it into their own digital wallets. 

Cryptojacking Methods

There are three main methods cryptojackers can opt for to maliciously mine for cryptocurrencies. Let’s skim through them so you know how to better protect yourself against them.

Browser-based Cryptojacking

This happens when the hacker uses IT infrastructure to mine and attack directly within the web browser. They create a crypto mining script that is embedded into different websites. These scripts can be embedded into out-of-date WordPress plugins or ads where they run automatically while the code gets downloaded into the user’s computer. 

File-Based Cryptojacking

File-based cryptojacking starts from downloading malware that runs an executable file. A Cryptomining script is spread through this file all around the IT infrastructure. The most common way to do so is to spread malicious emails with links or attachments that look fairly legitimate for the user to click on them. If they click, the code is executed and downloads the crypto mining script to work in the background on the user’s computer without their knowledge.

Cloud Cryptojacking

Cloud Cryptojacking is used when a hacker searches for API keys through an organization’s code and files to gain access to their cloud services. They then gather unlimited CPU resources for crypto mining and this resultantly increases account costs quite significantly. Hackers illicitly mine for currencies using this method as it helps them accelerate at a much faster rate. 

How to detect Cryptojacking?

The crypto mining scripts generated by hackers can be very tricky to detect and locate, which is why you need a highly vigilant IT team at work 24/7 for your organization’s operation. Here are some common signs that will tell you something’s wrong before it’s too late and practices that can help you detect cryptojacking, look out for these!

Overheating

Just like any other intensive task, Cryptojacking involves resource processing that can heat your computing device quickly. Overheating will shorten the lifespan of your device and damage it immensely. Moreover, overheating means the fans in your devices will run longer than they should to keep the system cool and running.

Decreased performance

One of the major signs of cryptojacking is a decrease in the performance of your laptop, PC, mobile device, or tablet. If you observe an unexplained decrease in processing speed, immediately call an IT technician and get it checked. If you’re running an organization, educate all your employees about their cybersecurity and about signs and symptoms they need to report. 

Regular Website Checks

Regularly monitor your website and all its web pages to make sure there are no changes to the files and webpages on the web server. This is a great way to prevent a Cryptojacking attack.

Monitor CPU Usage

Analyze your CPU usage regularly by using a task manager or activity monitor. An unjustified increase in the CPU usage means there’s something fishy going on. Especially for a website that has little to no media content that could drive traffic. 

Protection against Cryptojacking?

Following are some recommendations from security experts on the prevention of Cryptojacking.

Maintain good security hygiene

Establish solid security hygiene to lower the risk of Cryptojacking as all such attackers are opportunists and always on the hunt for wear, vulnerable venue. Hackers run numerous exploits on websites and get through whenever there is a patch.

Web filtering

Keep your web filtering tools up to date and make sure your users are blocked from accessing a webpage that you identified delivering Cryptojacking scripts. 

Anti-crypto mining browser extensions

To coin the cash and deploy the Cryptojacking script, crypto-miner hooks into web browsers. You can use browser extensions to block such crypto miners. Browser extensions such as No Coin, minerBlock, and Anti Miner can be used. 

Disable JavaScript and enabling Ad-Blockers

Disabling JavaScript when browsing online will protect Cryptojacking code from infecting your device. And, Ad-blockers will detect and block crypto-mining codes that are commonly placed in web ads.

TA: Bitcoin Price Back Below 100 SMA, Why BTC Could Retest $45K

Republished by Plato

Published

on

Bitcoin price failed to stay above $50,000 and $49,000 against the US Dollar. BTC is now below the 100 hourly SMA and it is likely to continue lower towards $45,000

  • Bitcoin started a fresh decline below the $50,000 and $49,000 support levels.
  • The price is now trading well below $50,000 and the 100 hourly simple moving average.
  • There is a connecting bearish trend line forming with resistance near $49,000 on the hourly chart of the BTC/USD pair (data feed from Kraken).
  • The pair could extend its decline towards $45,000 as long as it is below $50,000.

Bitcoin Price Turns Red

After forming a short-term top near the $52,600 level, bitcoin started a fresh decline. BTC traded below the $51,200 and $50,000 support levels to move back into a negative zone.

There was also a break below a major bullish trend line with support near $49,500 on the hourly chart of the BTC/USD pair. The pair even broke the $48,000 support level. There was a clear break below the 50% Fib retracement level of the upward wave from the $43,050 swing low to $52,650 high.

It is now trading well below $50,000 and the 100 hourly simple moving average. It seems like the bulls are trying to protect the 61.8% Fib retracement level of the upward wave from the $43,050 swing low to $52,650 high.

If they fail and the price trades below $46,500, there are chances of more losses. The next key support is near the $45,000 level, below which the bears might aim a test of the $43,000 support zone.

Fresh Increase in BTC?

If bitcoin stays above $46,500, it could correct higher. An initial resistance on the upside is near the $48,000 level. The first major resistance is near the $49,000 level and the 100 hourly simple moving average.

There is also a connecting bearish trend line forming with resistance near $49,000 on the same chart. To move into a positive zone, the price must clear the trend line resistance and then gain pace above the $50,000 barrier.

Technical indicators:

Hourly MACD – The MACD is now gaining momentum in the bearish zone.

Hourly RSI (Relative Strength Index) – The RSI for BTC/USD is now well below the 50 level.

Major Support Levels – $46,500, followed by $45,000.

Major Resistance Levels – $48,000, $49,000 and $50,000.

Analyst tells Tesla to dump Bitcoin for buybacks as shares plunge alongside MSTR’s

Republished by Plato

Published

on

A former equities CIO of Goldman Sachs drew an strong response on Twitter after suggesting Tesla should sell its Bitcoin and buy back company shares.

The price of TSLA shares have fallen 28% from $863.42 to $621.44, since news broke on Feb. 8 that Tesla had made a $1.5 billion BTC acquisition.

MicroStrategy’s shares have fared even worse in the short term. The company, which is headed by Bitcoin bull Michael Saylor and just completed its latest acquisition of $15 million in BTC on Mar. 3, is now down 50% from its all-time high of $1,315 from Feb. 9.

Tesla’s share market woes are likely due to a number of factors. In early February, it was reported that Tesla had been reprimanded by the Chinese government over quality control issues after receiving consumer complaints. The broader stock market has also experienced volatility, with the S&P 500 down 4.1% in the last 30 days. 

But the tweet from longtime Tesla analyst Gary Black, who has several decades of financial management experience, sparked a debate on whether Tesla’s purchase of $1.5 billion in Bitcoin last month had benefited investors.

“I don’t want them buying back stock,” said Twitter user Techgnostik. “I want them investing in growth, and making another billion on their BTC position.”

Black countered by suggesting TSLA would also draw inclusion by more fund managers with a share buyback program, considering it of greater value to the investor than buying BTC “with excess cash.”

Some users on Twitter agreed that a stock buyback seemed to be a more appropriate use of funds, while others felt too much attention was being paid to what Tesla did with 8% of their cash reserves.

It’s not easy to ascertain the impact buying Bitcoin has had on a company’s bottom line. While MicroStrategy’s share price has halved in a month, shares of MSTR are still up 340%, (from $146.63 to $645.66), since the company announced its first purchase of 21,454 BTC on Aug. 11, 2020. The price of BTC is currently up 310% from the same date.
