It is a common practice nowadays for online ventures to invite white hat hackers to attack their systems via security challenges or cyber bug hunts. Companies usually do this to learn what vulnerabilities they might have and improve, or to show their confidence in their existing defense capabilities. The method can also be used to prove a point about the reliability of a certain system as seems to have happened now with 0-conf BCH transactions.

0-Conf Challenge

Someone spent $2000 on a $1000 gift card trying to “double spend” bchIt appears that someone has lost $2,000 buying a $1,000 gift card trying to carry out a “double spend” attack with bitcoin cash (BCH), according to transaction data from Cryptonize.it. Whoever was behind this failed attempt thought that they can exploit a feature in BCH called 0-conf (wherein transactions are broadcasted immediately with still zero conformation), but the attempt backfired, costing them double the gain and verifying the security of the cryptocurrency for merchants.

As we previously reported, Cryptonize.it is an online shopping website selling gift cards for Amazon, Steam, iTunes, Starbucks and many other popular services. It exclusively accepts BCH payments, offering merchants a platform to sell their products to the bitcoin cash community while avoiding volatility risks. As such, it was important for the founders of the site to demonstrate to merchants that accepting payments with the BCH cryptocurrency is safe and secure. So the company challenged anyone who think they can double spend by exploiting 0-conf to get a $1000 Amazon gift card (priced at $2000 to make sure no one buys it by mistake), promising not to report the incident to Amazon or to press any charges.

More Challenges to Come

Someone spent $2000 on a $1000 gift card trying to “double spend” bchCryptonize.it co-founder Arian Kuqi explained to news.bitcoin.com how the whole thing came about: “It started about a month ago, I noticed a lot of comments and posts about 0-conf and how it’s not safe to use. It’s understandable, people are stuck in their head with BTC problems and think the same goes for BCH. Having 0-conf on cryptonize.it, I started commenting and posting about it. Then, a user on reddit suggested I set up a challenge for people who were so confident 0-conf can’t possibly be reliable so one day later I did. A month went by, a lot of talk in the beginning but no action. Until one guy made it clear that he was going to try under the impression of a 80% shot in his favor. A couple of days later, it happened!”

The co-founder added that more similar challenges are on the way: “I’m going to keep coming with challenges until everybody is satisfied 0-conf is safe to use for any online retailer supporting bitcoin Cash or until these trolls run out of money. My goal is to show merchants the benefits and safety of the bitcoin Cash ledger and attract more adoption by merchants.”

Bitcoin Price Analysis: After Giddy Heights, Bitcoin Sees a Steady Decline in Price

Bitcoin Price Analysis

In the days leading up to the various bitcoin futures markets opening, bitcoin saw a push to fresh all-time highs near $20,000. However, shortly after reaching these values, the market saw a steady decline in price as demand dwindled and supply began to dominate the market. In the last bitcoin market analysis, we discussed a possible distribution phase for bitcoin and a potential hypodermic breakdown of the strong, parabolic trend the market has seen. Let’s take a look the latest developments:

One troubling aspect of this current price trend is the high volume leading into all the dips, and the low volume on the price rises. This price action shows both the diminishing demand in the market and the overwhelming supply that is beginning to take dominance in the market. Currently, bitcoin is perched on a potential part of the trading range called “Last Point of Supply” (LPSY): this offers a final opportunity for the large players who have not exited the market to finally exit before an ultimate correction.

As discussed in the previous article, there is a strong, aggressive trend called the hypodermic trendline:

Figure_2 (1).JPGFigure 2: BTC-USD, 4-Hour Candles, Hypodermic Trendline

The hypodermic trendline represents a break outside of the parabolic envelope that dominated the market trend for over three years. The hypodermic trend also represents an aggressive price trend that is fairly difficult to maintain because of the demand required to keep the price aloft.

Currently, the price is sitting below this trendline and has rejected its initial test of the trend. At the moment, BTC-USD is testing the support of the trading range (shown in blue) and is systematically going through support tests as the market finds new lows.

A breakdown of this hypodermic trend, and a possible breakdown of this trading range, could easily send the market down to test the parabolic curve (shown in black):

There is likely to be very strong support along the parabolic trend that will stifle any potential price drops. As always, it’s important to watch the volume with the price growth or drops to confirm the likely direction of a move. As we test new lows, any volume growth will likely signal a continuation of the downtrend and ultimately have us testing the lower boundaries of the trading range.

Summary:

  1. bitcoin is potentially at its Last Point of Supply as it begins to test new lows in its current downtrend.

  2. bitcoin broke below the hypodermic trendline, which usually signals a breakdown in trend.

  3. Support will be found along the lower boundary of the trading range and will likely slow down any potential price drops.
