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。

EduSeries #2: Reality $MANTA  ‌Many retail investors still hope $MANTA to fly to $10 without ever considering tokenomics indicators. Let’s analyze the underlying reality mathematically so you don’t keep becoming exit liquidity.
Technologically, Manta Network (Manta Pacific) is actually solid. They are an Ethereum Layer 2 that uses Celestia for Data Availability (DA), making gas fees in its ecosystem very cheap. However, the critical problem isn’t in the technology, but in its economic structure.
Manta was launched with a classic VC release strategy: Low Float, High FDV. This means the circulating supply at launch was very small, while billions of tokens are still locked for the team, advisors, and early investors. Periodically, these vested tokens are unlocked and enter circulation, creating constant selling pressure.
The simple calculation: With a total supply of 1 billion tokens, if MANTA hits a price of $10, then the FDV (Fully Diluted Valuation) must reach $10 billion. This incredible figure forces Manta to compete directly with giant Layer 2 solutions whose ecosystems are far more mature. Every time the price tries to climb, the selling wall from unlocked tokens is ready to dampen it.
In conclusion, $MANTA still has good infrastructure utility, but the $10 target is a heavy illusion. In the Web3 world, good code doesn’t automatically make token prices fly endlessly.

【$WIF Signal】Bearish funding rate is extremely negative; pull back to go long for a sniper setup  
RSI 1H 73, 4H 86; funding rate -0.62%, short positions’ costs have surged. Buying depth ratio is 1.60%, and selling pressure is absorbed quickly. The 4H MACD histogram continues to expand, but the price has deviated too far from the EMA20.  
🎯 Direction: Long (place a pullback order)  
⚡ Entry/Order: 0.1987  
🛑 Stop loss: 0.1908  
🚀 Target 1: 0.2349  
🚀 Target 2: 0.2358  
🛡️ Trade management:  
- Execution strategy: After the order is filled, if the price reaches 0.2349, reduce position size by 50% and move the stop loss to break-even. If it is not filled, the order becomes invalid.  
Depth logic: 0.1987 corresponds to the convergence zone of the 4H EMA50 and the middle Bollinger band, providing technical support. If the current negative funding rate persists, the pressure from short covering will push the price back up. The risk-reward ratio is about 4.6, making it worth waiting in ambush.

22 billion USD poured into hardcore applications: a16z flips the script against the trend—could the crypto world be about to change?
In this winter when fundraising is harder than reaching the sky, a16z suddenly rolled out its fifth crypto fund of 2.2 billion USD. This big pile of money isn’t intended to go after empty, flashy speculation in the air—it directly targets real applications that you can see and touch, such as stablecoins, asset tokenization, and on-chain finance. This added push isn’t just a symbolic boost to the market—it injects confidence into it.
It also more clearly signals that the direction of Web3 has fundamentally changed: capital no longer buys into pure storytelling—they want hard infrastructure that can solve real problems!
Even more interesting changes are happening in personnel arrangements. CTO Eddy Lazzarin has been promoted to general partner, which means a16z’s investment logic is shifting from marketing-driven to technical hard-core. This shift instantly makes projects like EigenCloud—sitting right at the intersection of Restaking and AI—turn into hot tickets. When top-tier venture capital firms start handing the purse strings to people who actually build technology, the infrastructure that aims to use AI to improve blockchain efficiency and move assets on-chain will finally enter a true breakout period.
With the big players leading the charge, the market’s mood still has a bit of cautious optimism. On the one hand, people believe this money can push the narrative of combining AI and crypto to new heights, reviving sectors that have been stuck with liquidity drying up; but on the other hand, everyone is watching the macro environment. After all, the market at the beginning of 2026 isn’t exactly warm. If the overall market’s total value continues shrinking, then pumping in blood from just one giant may not be enough to save all projects—because the truth that one tree can’t support a forest is something everyone understands.
Even though a16z is flush with cash, they cast a wide net. That means not every portfolio company can receive enough resources to dramatically change its fate. Especially for projects like EigenCloud that are deeply tied to the Ethereum ecosystem: if Ethereum itself performs weakly, these AI infrastructure projects built on top of it are likely to run into a ceiling. The key game right now is this: before the market turns around, can this 2.2 billion USD truly “nurture” these hardcore tracks into building real moats?
a16z’s move is basically telling everyone: don’t go chasing the fake stuff—the future depends on hands-on technology and real applications. Right now, they’re putting their money on the two big legs of infrastructure and AI. If you’re a long-term investor, this is a signal that big money is still flowing in; but if you’re hoping to get rich instantly just because this news broke, then you should stay calm. After all, when big capital enters, it still needs time to lay out the plan. We have to see whether this money can ultimately smash out a few truly useful products, instead of producing a bunch of code nobody uses.
