Pourquoi acheter Ethereum(ETH) ?

Qu’est-ce qu’Ethereum ? Une plateforme pour les contrats intelligents et les applications décentralisées
Ethereum (ETH), fondé par Vitalik Buterin en 2015, est la première blockchain publique au monde à prendre en charge les contrats intelligents. Ethereum permet aux développeurs de créer des applications décentralisées (dApps), des protocoles DeFi, des NFT, et bien plus encore, contribuant fortement à la croissance de l’écosystème Web3. L’Ether (ETH) est le jeton natif du réseau Ethereum.
Comment fonctionne Ethereum ? EVM, frais de gas et consensus
Ethereum repose sur un réseau de nœuds distribués, chaque transaction nécessitant des frais de “gas” payés en ETH. Les contrats intelligents permettent l’exécution automatique d’accords conditionnels, largement utilisés dans la finance, les jeux, la logistique et bien d’autres secteurs. Initialement basé sur la preuve de travail (PoW), Ethereum a finalisé sa mise à jour “The Merge” en 2022, passant entièrement à la preuve d’enjeu (PoS), réduisant ainsi sa consommation d’énergie de plus de 99 % tout en renforçant sa durabilité et sa sécurité.
Mécanisme d’offre et EIP-1559
Ethereum ne possède pas de plafond d’offre fixe, mais depuis la mise en place de l’EIP-1559, une partie de l’ETH est brûlée à chaque transaction, ce qui contribue à réduire la pression inflationniste. L’ETH est essentiel pour payer les frais de gas, recevoir des récompenses de staking et participer à la gouvernance. La demande en ETH augmente avec l’expansion de l’écosystème.
Écosystème et cas d’usage
Les standards ERC-20 et ERC-721 d’Ethereum ont largement contribué à l’essor de la DeFi et des NFTs, donnant naissance à des projets emblématiques comme Uniswap, Aave ou OpenSea. La machine virtuelle Ethereum (EVM) offre un environnement de programmation flexible, favorisant l’interopérabilité entre blockchains ainsi que le développement de solutions de mise à l’échelle de type Layer 2, telles que les Rollups ou le Sharding.
Raisons et risques liés à l’investissement dans Ethereum
Infrastructure Web3 et contrats intelligents : l’ETH est l’actif central de la DeFi, des NFT, des DAO et d’autres applications innovantes. Améliorations techniques et croissance de l’écosystème : la transition vers la preuve d’enjeu (PoS) et l’EIP-1559 améliorent les performances du réseau et la capture de valeur. Forte liquidité et adoption généralisée : l’ETH est échangé dans le monde entier, et se classe juste derrière le Bitcoin en termes de capitalisation. Risques : congestion du réseau, frais de gas élevés, concurrence des blockchains émergentes (comme Solana, Avalanche), et incertitude réglementaire.
Points de vue sceptiques et perspectives alternatives
Bien que l’écosystème d’Ethereum soit vaste, des problèmes de scalabilité et de frais élevés persistent. S’ils ne sont pas résolus, Ethereum pourrait se faire dépasser par des blockchains plus récentes et plus performantes. Les investisseurs doivent rester attentifs aux avancées technologiques et à l’évolution de l’écosystème.

BNB Outlook for Wednesday, August 12
BNB is performing slightly better than most altcoins today, with the current price around $612. It has posted a modest 24-hour gain, with an intraday range of $598–$619. Trading volume has increased somewhat from the previous period, and the overall market is consolidating with a bullish bias. Market participants are also waiting for the U.S. CPI inflation data to be released tonight before choosing a broader direction.
Technically, the key short-term resistance level is $618–$620, while the 200-day moving average at $627 represents a significant resistance level. Short-term support is at $598–$600, the key pullback level today. As long as the price does not decisively break below this level, the short-term bullish pattern can be maintained.
Trading recommendation: short at $615–$618, target $608–$600$BTC $ETH $SOL

Bitcoin continues to face pressure below the 63,800 resistance level, falling to 63,200 before entering a range-bound consolidation phase. The bulls have attempted to counterattack several times but have still failed to break through and hold above the key resistance level at 63,800. The rebound remains weak and is merely a technical recovery, with insufficient upward volume. Strong resistance lies at 64,000–64,500.
The strategy remains focused on selling into rebounds, with close attention to support at the previous lows below. Once consolidation ends and the price breaks downward, a new round of decline will begin.

What would happen to Bitcoin if miners stopped mining one day?
Don’t dismiss this as science fiction.
Just yesterday, Riot Platforms—one of the largest publicly listed Bitcoin mining companies in the United States—did something unexpected:
It signed a 20-year computing-capacity lease with AI company Anthropic worth $9.1 billion.
If both renewal options are exercised, the total value could reach $16.1 billion.
Following the news, Riot’s after-hours stock price surged 25%. Bernstein directly raised its price target from $30 to $35.
A mining company stopped mining, and its stock price soared instead.
Think about that.
Here are the contract details:
Riot is leasing 191 megawatts of power capacity at its Rockdale campus in Texas to Anthropic. What does 191 megawatts mean? It’s enough to power 143k households simultaneously.
The first 96 megawatts will be delivered next December, with the full capacity coming online by June 2028.
Riot’s total revenue in the second quarter was $174.2 million, up 14% year over year. Its data center business generated $23.2 million, while its engineering business generated $37.3 million—the latter growing by more than 200% year over year.
But the AI contract is worth $9.1 billion per year.
For comparison, how much revenue did Riot generate in all of last year?
One contract is worth dozens of years of mining revenue.
And Riot is not the first.
In July this year, another mining company, TeraWulf, signed a 20-year, $19 billion lease with Anthropic to provide 401 megawatts of capacity.
Core Scientific signed AI hosting contracts worth tens of billions of dollars with CoreWeave long ago.
The entire mining industry is collectively “switching sides.”
Why?
Because mining is no longer profitable.
After the Bitcoin halving, production costs at some mining companies reached as high as $78,000, while the spot price was between $63,000 and $65,000.
They lose more than $10,000 for every coin they mine.
Network hashrate fell from its peak of 1,160 EH/s to approximately 920 EH/s. Mining difficulty has declined by nearly 20% from its peak.
This is not a transformation. It is an escape for survival.
So what does this deal mean for crypto?
Three things, each of which could change the rules of the game.
First: Selling pressure from miners could ease.
In the past, miners had to sell coins regularly to pay electricity bills and repay loans. Once AI revenue becomes a stable source of cash flow, miners will no longer be forced to sell at the bottom.
Some analysts predict that by the end of 2026, AI could account for **as much as 70%** of the revenue of certain mining companies.
Seventy percent of their revenue would be unrelated to Bitcoin’s price.
What does that mean?
It means miners’ sensitivity to Bitcoin’s price is declining sharply.
Second: The valuation logic for mining companies has changed.
How did Wall Street value mining companies in the past?
By looking at Bitcoin’s price.
When Bitcoin rose, miners rose. When Bitcoin fell, miners fell. Mining companies were essentially leveraged bets on Bitcoin.
Now things are different.
Bernstein analysts said Riot is proving to Wall Street that it is “not just a Bitcoin mining company.” The stable dollar revenue from a 10-year AI contract is “completely different” from block-reward revenue that is halved every four years.
From “Bitcoin cycle stocks” to “AI data center REITs.”
When the valuation logic changes, the ceiling for the stock price changes too.
Third: Bitcoin’s hashrate moat is becoming thinner.
This may be the most overlooked point.
What secures Bitcoin? Hashrate.
What supports hashrate? Miners.
What supports miners? Mining revenue.
If the biggest mining companies are all selling their power to AI, who will protect the Bitcoin network?
Riot’s Rockdale campus once echoed with the roar of tens of thousands of Bitcoin mining machines. Now, those sounds are being replaced by GPU servers.
Bitcoin’s vaunted “hashrate moat” is being gradually drained by AI.
Here’s the painful truth—
Miners’ faith in Bitcoin is being defeated by cash flow.
It’s not that they stopped loving it. They simply can’t survive.
Losing $19k on every coin mined, who wouldn’t leave?
AI has given them a way to survive: stop being miners and become landlords.
Lease out the power and facilities, collect stable rent, and forget about fluctuations in the coin’s price.
What’s not to like? It’s so appealing that it makes people forget why they started mining in the first place.
In the short term, this $9.1 billion contract is a victory for Riot. In the long term, it is a turning point for the Bitcoin ecosystem.
When miners no longer depend on mining revenue, will they still care about Bitcoin’s price?
When hashrate changes from a network-protection mechanism into a leased commodity, will Bitcoin’s security foundation remain stable?
There are no answers to these questions today.
But the trend is already irreversible.
The sound of mining machines at the Rockdale campus in Texas is fading away.
In its place is the hum of AI servers.
Bitcoin’s “hashrate era” may have reached a turning point without anyone noticing.
