なぜイーサリアム(ETH)を購入するのか?

イーサリアムとは何ですか?スマートコントラクトおよび分散型アプリケーション向けプラットフォーム
イーサリアム(ETH)は2015年にVitalik Buterinによって設立され、スマートコントラクトをサポートする世界初のパブリックブロックチェーンです。イーサリアムは開発者が分散型アプリ(dApp)、DeFiプロトコル、NFTなどを構築できるようにし、Web3エコシステムの急速な成長を牽引しています。イーサ(ETH)はイーサリアムネットワークのネイティブトークンです。
イーサリアムはどのように機能しますか?EVM、ガス手数料、コンセンサス
イーサリアムは分散型ノードに依存しており、すべての取引には「ガス手数料」としてETHが必要です。スマートコントラクトは条件付き契約を自動で実行し、金融、ゲーム、サプライチェーンなどで広く利用されています。当初PoWを採用していたイーサリアムは、2022年に「The Merge」アップグレードを完了し、完全にPoS(Proof of Stake)へ移行しました。これにより、エネルギー消費が99%以上削減され、持続可能性とセキュリティが向上しました。
供給メカニズムとEIP-1559
イーサリアムには固定供給上限はありませんが、EIP-1559以降、各取引でETHの一部がバーンされ、インフレ圧力の軽減に役立っています。ETHはガス手数料の支払い、ステーキング報酬、ガバナンス参加に必須であり、エコシステムの拡大とともに需要も増加しています。
エコシステムとユースケース
イーサリアムのERC-20およびERC-721規格はDeFiやNFTの台頭を後押しし、Uniswap、Aave、OpenSeaなどのプロジェクトを生み出しました。イーサリアム仮想マシン(EVM)は柔軟なプログラミング環境を提供し、クロスチェーンの相互運用性やレイヤー2スケーリングソリューション(例:Rollups、Sharding)を促進します。
イーサリアム投資の理由とリスク
Web3とスマートコントラクト基盤:ETHはDeFi、NFT、DAO、その他の革新的なアプリケーションの中核資産です。 技術的アップグレードとエコシステム成長:PoSへの移行やEIP-1559により、ネットワークのパフォーマンスと価値獲得が向上します。 高い流動性と主流受け入れ:ETHは世界中で取引され、時価総額ではビットコインに次いで2位です。 リスク:ネットワーク混雑、高いガス手数料、新興ブロックチェーン(例:Solana、Avalanche)からの競争、規制の不確実性。
懐疑的な見解と代替的視点
イーサリアムのエコシステムは広大ですが、スケーラビリティや手数料の問題は依然として残っています。これらの課題に対処できなければ、新しく高性能なブロックチェーンに追い越される可能性があります。投資家は技術の進展やエコシステムの変化を注視する必要があります。

Crypto Today: Bitcoin, Ethereum, XRP eye next leg up on growing risk-on sentiment :
Bitcoin rises above $117,000 after the Federal Reserve interest rate decision and the dot plot's dovish outlook.
Ethereum steadies around $4,600 despite minor ETF outflows.
XRP bulls regain control of the trend, targeting a breakout toward the $3.66 record high.
Bitcoin (BTC) edges higher above the $117,000 level on Thursday, buoyed by growing bullish sentiment in the broader cryptocurrency market. The uptick in the BTC price is accompanied by steady increases in altcoin prices, with Ethereum (ETH) and Ripple (XRP) poised for a short-term breakout toward their record highs.
Market overview: Crypto markets recover on improving market sentiment 
The United States (US) Federal Reserve (Fed) 25-basis-point interest rate cut on Wednesday was widely expected, but what caught the attention of investors was the dot plot, which showed that most Fed policymakers expect a rate cut at each of the remaining meetings of the year.
The 25 bps cut has brought the benchmark interest rate to a new range between 4.00% and 4.25%, a decision approved by 11 of the 12 members of the Federal Open Market Committee (FOMC), citing a softer labor market, a higher unemployment rate, and sticky inflation.
Participants in the cryptocurrency market welcomed the rate cut decision, fueling speculation in riskier assets. Wednesday’s decision has laid the foundation for two more rate cuts this year. 
Chart of the day: Bitcoin eyes $120,000 breakout 
Bitcoin has settled above the $117,000 level, buoyed by strong risk-on sentiment as investors prepare for the potential impact of the upcoming rate cuts on riskier assets.
The Relative Strength Index (RSI) recovery to 61 from a low of 37 on August 31 indicates bullish momentum is building. Higher RSI readings, approaching overbought territory, would back the steady risk-on sentiment, increasing the chances of Bitcoin price breaking above the $120,000 hurdle.
Traders will look for a buy signal from the SuperTrend indicator to ascertain BTC’s ability to sustain the uptrend, aiming at its record high of $124,497 reached on August 14. 
Still, if investors book early profits, attention could shift to tentative support levels such as the 50-day EMA at $113,796 and the 100-day EMA at $111,608.8.
Altcoins update: Ethereum, XRP eye new all-time highs
Ethereum is on the verge of breaking above a descending trendline resistance, which has been in place since the smart contracts token hit a record high of $4,956 on August 24.
The uptrend is supported by key upward-facing moving averages, including the 50-day EMA at $4,229, the 100-day EMA at $3,786, and the 200-day EMA at $3,327.5.
These moving averages serve as tentative support levels if profit-taking and unexpected marketing dynamics trigger a major sell-off.
The RSI position at 57-56 indicates a potential extension of the leg up toward overbought territory, which could reinforce bullish momentum. A breakout above the trendline resistance and the supply areas between $4,800 and the record high of $4,956 would usher in a new era for Ethereum, potentially above the $5,000 psychological level.
However, it is worth mentioning that Ethereum spot Exchange-Traded Funds (ETFs) saw minor outflows of $1.89 million on Wednesday, extending the bearish streak from Tuesday. 
If institutional investors choose to stay on the sidelines and perhaps reduce their exposure, a major upswing above $5,000 could be a pipe dream, with the Ethereum price likely to favour a correction below the 50-day EMA support at $4,229 to collect more liquidity before making another recovery attempt.
As for XRP, bulls are showing strength above the $3.00 level, with the 50-period Exponential Moving Average (EMA) at $2.956 providing additional support. A recovery of the Relative Strength Index (RSI) on the daily chart to 59 from 51 on Monday supports XRP’s short-term bullish potential.
A bullish reversal above the next key hurdle at $3.186, which was last tested on Saturday, would boost the chances of a bullish outcome toward the round-number supply area of $3.50 and the record high of $3.66.

"If winter comes, can spring be far behind?" ✨
​👁️ We have seen ALGO go through its 'hibernation' period, where the Bears consistently pushed the price down with sell-offs and negative news. But now, perhaps it's time for the ALGO Tiger to awaken. Let's wait and see the long-suppressed potential power explode 🦁.
​🛒 A discounted price for accumulation. Buy on the dip; if the price drops by 5-10%, add another 5% of your NAV. 💎ALGO💎 is undervalued 🦈. Be patient and don't be hasty 🦁.
​❓Are you afraid of going against the crowd? Afraid to buy when the price is falling? What is the real trend you should follow? It's the realization of Blockchain technology. Don't let your psychology dictate your actions 🐊.
​🦈 Suggested investment strategy:
Flexible capital allocation: Consider allocating a reasonable portion (10-20% of NAV) to ALGO.
🚆 Target: Set a profit target of 2-3x.
✨ Why is ALGO worth paying attention to?
Algorand is an ambitious Layer 1 blockchain platform aiming for a decentralized, secure, and transparent future. ALGO is highly valued for its ability to solve the "blockchain trilemma," balancing security, decentralization, and scalability. It also complies with ISO 20022, has institutional appeal, and features a roadmap that includes Falcon post-quantum cryptography, Rocca wallet, Alpha Arcade, partnerships with Nansen, and the Harvard hackathon.
​🔥🔥🔥 Each of us contributes a little, and we will make the ALGO gems scarce!
