Pourquoi acheter Bitcoin(BTC) ?

Qu'est-ce que le Bitcoin ? La naissance de l'or numérique décentralisé
Le Bitcoin (BTC) a été introduit en 2008 par Satoshi Nakamoto et officiellement lancé en 2009 comme la première cryptomonnaie décentralisée au monde. Il permet des paiements électroniques de pair à pair, sans l’intervention d’intermédiaires comme les banques ou les gouvernements. Toutes les transactions sont enregistrées sur une blockchain publique, garantissant transparence et sécurité.
Comment fonctionne le Bitcoin ? Consensus PoW et technologie blockchain
Le Bitcoin fonctionne selon un mécanisme de consensus appelé preuve de travail (Proof of Work – PoW). Lorsqu’Alice souhaite envoyer 1 BTC à Bob, les mineurs entrent en compétition pour résoudre des problèmes mathématiques complexes. Le premier à y parvenir reçoit une récompense en bitcoins (block reward) et enregistre la transaction sur la blockchain. Ce système sécurise le réseau, mais entraîne une consommation d’énergie élevée et une difficulté de minage croissante.
L’offre de Bitcoin et le mécanisme de halving
L’offre de Bitcoin est strictement limitée à 21 millions d’unités, ce qui en fait un actif à la rareté absolue. Tous les quatre ans, un événement appelé “halving” réduit de moitié la récompense versée aux mineurs, ralentissant ainsi l’émission de nouveaux bitcoins. Ce mécanisme renforce les propriétés anti-inflationnistes de Bitcoin et constitue l’un des principaux moteurs de son appréciation à long terme. Fin 2024, plus de 19,7 millions de bitcoins ont déjà été minés.
Historique des prix et impact sur le marché
Le Bitcoin a commencé avec une valeur quasi nulle, atteignant environ $20,000 in 2017 and hitting new highs above $60 000 en 2021. Il a connu une volatilité extrême — comme en témoigne le célèbre “Bitcoin Pizza Day”, marquant sa première utilisation commerciale. Bien qu’il ait été qualifié de bulle ou d’arnaque dans le passé, l’adoption croissante par le grand public et les institutions a propulsé sa capitalisation au-delà de 1 000 milliards de dollars.
Raisons d’investir dans le Bitcoin et risques associés
Couverture contre l’inflation et réserve de valeur : L’offre fixe et les événements de halving font du Bitcoin un or numérique et un actif refuge potentiel. Forte liquidité : Le BTC est négocié sur toutes les principales plateformes, permettant une allocation facile du portefeuille. Décentralisation et autonomie : Non contrôlé par une entité centrale ; les utilisateurs gardent un contrôle total sur leurs actifs. Risques techniques et réglementaires : Forte volatilité, réglementation incertaine, préoccupations environnementales liées au minage, et utilité limitée pour les paiements.
Points de vue sceptiques et perspectives alternatives
Malgré son caractère révolutionnaire, le Bitcoin reste peu efficace en tant qu’outil de paiement, et les risques réglementaires demeurent importants. Certains experts considèrent le Bitcoin davantage comme un actif spéculatif que comme une réserve de valeur stable. Les investisseurs doivent évaluer attentivement leur tolérance au risque.

Yesterday, when Xiao Yu left, I told you that the “big pie” would go to around 644, and once it hit that level, I would enter the trade. Then I exited around 649. Xiao Yu is smart—he placed an order, got filled, and exited around 650. Originally, I really wanted to short around 650, specifically at 65026; I’d already entered the price and the order position size. But I didn’t place the order because I knew that once I did, I’d probably have to keep staring at the chart. I was afraid the market maker/manipulator would come and hit me—then I’d have to stay up late again.
Thinking it over, I’d better go to sleep earlier. I went to bed around 1 a.m., but I woke up again in the early morning and got up to check. And sure enough, if the downside played out as I predicted, I’d see whether it could drop to around 636.
I remember a fellow coin trader asked me where to set the stop loss. At that time, the lowest point was around 64390, so I told him to set the stop loss at 64380—just 10 points. I don’t know whether that friend exited. If he didn’t, he might have been stopped out, or ended up stuck in a loss. I already said it clearly: I don’t place trades for you—I’m responsible for my own profits and losses.
While I was still writing the article, the “big pie” dropped to around 636. It really gave face.
For a target’s long-term investment-style forecast—for example, the big pie—when you’re talking about seeing 100k or 200k, the difficulty isn’t really that high. But if you can accurately predict within 1 hour or 4 hours exactly how far the big pie will rise and where it will fall to, that difficulty is higher than the former. If you don’t believe me, go ahead and try it yourself.
I used to not be able to get it right either. After practicing for so long, I still can do it now—where are the “experts”? Real experts are made through diligent study and hard practice. All these years of staying up late, watching the chart, placing trades—only in the end did I get results like this. How could making money be so easy? Isn’t it all done one step at a time, one solid stride after another, until you finally reach the goal?! Although I’m better than before, I will always keep a sense of awe for the market. I know my pride and arrogance will be my grave in the future. Only by staying humble and maintaining a positive and optimistic attitude toward learning can I go further!
After I finish writing the article, I still have to go back to sleep—I’ll try to stay up less! And I hope everyone won’t stay up late either—money can’t be made all at once.
Someone questioned me for not posting trade screenshots. I don’t want anything from you, so there’s no need to post them. If you doubt my level, there’s an offline office in Chongqing—I stay there long-term, because I trade from the office. If you come, I’ll make you fully convinced. Bad words up front: if my brother comes, there’ll be good wine; if that money-hungry wolf comes, the only thing waiting for him is a hunting rifle!

The earlier part of the price action looked pretty strong, but in reality every time it surged up, people kept selling into it, and the price simply couldn’t hold. Honestly, at first I was also worried I’d read it too early—after the short around 0.4076 showed up, the market then kept pulling back and tugging for a few rounds, almost grinding my patience away.
 
The most critical change was this: after the rally-to-peak and pullback, it didn’t quickly reclaim like it had before. Instead, it went weaker wave after wave. The move went from 0.4076 down to 0.325, and the final result came back at +1437.91%. This short wasn’t based on guessing—it was held only after the real selling pressure finally loosened.
 
A lot of people see the drop and then try to chase it, but usually they run into a rebound as soon as they get in. For me, this time felt more like a reminder: you can look short from the high, but you must wait until the market exposes the problem—don’t let yourself get carried away by the first big bearish candle.

This short trade could be taken, but the key isn’t chasing a single big bearish candle. Instead, it was that after seeing heavy pressure in the high zone, the rebound never truly managed to hold. $FF placed a short action around 0.10466. I actually hesitated at the time too, because the consolidation period beforehand dragged on for too long, and if you hesitate or your hand slips, you can easily get washed out by a needle-like spike.
 
Later, several times price surged up and then pulled back. The bid support kept getting weaker. Once the sell-off hit, the direction became completely clear. The short went from 0.10466 to 0.06134. This result is recorded at +1998.37%. The hardest part during the process wasn’t placing the order—it was waiting.
 
After you’ve been in the crypto圈 long enough, you’ll know many people don’t make a mistake in their analysis; they just don’t wait for the logic to play out, and they get off early. This level made me more confident in the bearish call. A trade you’re truly sure about doesn’t need to “prove yourself” by chasing orders.
