GreenAddress (and its reimplementation GreenBits), the Bitcoin wallet that was acquired by blockchain infrastructure company Blockstream earlier this year, is the first mobile wallet to offer Segregated Witness (SegWit) transactions. This means that GreenAddress users are among the first to benefit from lower fees and faster transaction times enabled by the long-awaited protocol upgrade.

“The Bitcoin network is currently not being spammed, so transactions with low fees are getting confirmed — however, with SegWit the required fees are even lower; they’re almost cut in half,” GreenAddress developer Lawrence Nahum told Bitcoin Magazine.

Once upgraded, all new addresses generated by the GreenAddress wallet will be SegWit addresses (though wrapped in a P2SH address, so they still look the same as before). Receiving payments on these addresses does not differ from typical addresses in any way, nor does spending bitoins from different addresses. But when users spend the bitcoins from the SegWit addresses later on, the protocol upgrade is utilized. This outgoing transaction that requires lower fees will be included in a block more quickly.

GreenAddress is not the first wallet to enable SegWit: hardware wallets Ledger and Trezor introduced the new feature last week. But in both cases, of course, using the new feature requires owning such hardware devices. GreenAddress, on the other hand, is available to anyone with a smartphone or a computer; if the fees on competing wallets are too high, users can easily switch to GreenAddress.

“We are now the first mobile wallet to implement the solution, but I feel the ecosystem, unlike with previous soft fork upgrades, is moving really fast,” Nahum said. “Hardware wallets are leading, Armory also has support, Bitcoin Core will have it in the 0.15.1 release, and I’m sure the others will move fast as they have strong incentives: In GreenAddress transaction fees are pretty much halved.”

Interestingly, the malleability fix that Segregated Witness provides will be utilized by GreenAddress as well. Due to malleability — the ability to change the appearance of unconfirmed transactions — spending bitcoins from unconfirmed transactions could fail due to meddling of third parties. While this will not lead to a loss of funds, it could make for a bad user experience, which is why it wasn’t available to most users. With the malleability fix, this issue will now be resolved, and GreenAddress users can re-spend unconfirmed bitcoin balances straight away.

Over the years, GreenAddress has made a name itself by pioneering new features enabled by Bitcoin protocol upgrades. The wallet was, for example, the first to offer opt-in replace-by-fee, which allows users to bump the fee of an outgoing transaction. It was also among the first wallets to offer modern multisig addresses, the first wallet to include fee estimation instead of static fees, the first mobile wallet to support hardware wallets, and more.

After Labor Day weekend, many ETH-USD traders were surprised to find a 30% market drop over the course of 3 days. After an initial drop to the $330s, the ETH-USD market suffered another blow as China announced it will be banning ICOs and conducting rigorous investigations into several of the newer coins such as NEO and OMG. This announcement from the Chinese government prompted several large Chinese exchanges to begin delisting coins under investigation. After all was said and done, the drop to $280 marked a 38% retracement since ETH-USD bull run from $130 to $400 values:

After seeing the test of the macro 38% Fibonacci Retracement values (shown above), the ETH-USD markets managed to bounce to the 23% retracement values. At the time of this article, the market is currently finding support at 23% retracement but the steam to continue a sustained bull run is waning.

Looking closely at the current trend, we can see a potential bearish continuation pattern called a “Bear Flag”:

A Bear Flag is a bearish continuation pattern that is characterized by higher highs, higher lows, and decreasing volume. Bear Flags are found at the bottom of bear runs and are sometimes referred to as “Bull Traps” because bullish traders are often caught in these patterns by mistaking the rally for a macro trend reversal.

Typically, the Bear Flag is formed by strong bullish traders buying what they predict is the bottom of the bear run. The initial purchasing power of the bulls begins to push out the bears who either wish to take profit or were late to the bear run — this is called a “short squeeze.”

However, one key characteristic to watch out for in trends like this is the drastically decreasing volume throughout the length of the run. The decrease in volume essentially shows the lack of buyers in the market as the price begins to climb, level out and ultimately reverse.

To calculate where the potential price target of this Bear Flag is, we must first calculate the “pole length” of the flag:

If this pattern breaks down and proves to be a successful Bear Flag, we can expect to see an approximate $90 move downward from the point of breakout. In our case, we could expect a retest of the of the 38% Fibonacci Retracement values ultimately leading to a test of the 50% retracement values shown in Figure 1.

As always, it is paramount to confirm the trend before trading it. Although Bear Flags are strong patterns and tend to have a high degree of success among some of the more seasoned traders, it is entirely possible the market could see a flood of volume to propel the price higher; alternatively, the price could simply level off and consolidate sideways. There is no rule that states “the market must continue downward.” However, for those looking to trade this pattern, it is advisable to wait for a downward price movement to be confirmed with strong, bearish volume.

Zooming out to the 1-day candles, we see indications that a sustained bear market could be in store for ETH-USD. The 1-day candles reveal a bearish MACD with no clear signs of divergence (bearish momentum loss). A bearish macro MACD and waning volume on the lower timescales is a great indication of a potential prolonged bearish continuation.

Summary:

1. China announced a ban on ICOs and began delisting several newer coins from their major exchanges.

2. There are macro and micro signs that a bearish continuation could be in store for ETH-USD.

3. Should the Bear Flag break to the bottom, we can expect a test of the mid-$200s.
