なぜビットコイン(BTC)を購入するのか?

ビットコインとは何ですか?分散型デジタルゴールドの誕生
ビットコイン(BTC)は、2008年にサトシ・ナカモトによって提案され、2009年に世界初の分散型暗号通貨として正式にローンチされました。銀行や政府などの仲介者を介さず、ピアツーピアの電子決済を可能にします。すべての取引はパブリックブロックチェーンに記録され、透明性とセキュリティが確保されます。
ビットコインはどのように機能しますか?PoWコンセンサスとブロックチェーン技術
ビットコインは、プルーフ・オブ・ワーク(PoW)コンセンサスメカニズムで動作します。アリスがボブに1 BTCを送金したいとき、マイナーは複雑な数学的問題を解くために競争します。最初に問題を解いたマイナーは、新しいビットコインをブロック報酬として獲得し、取引をブロックチェーンに記録します。このシステムはネットワークを安全にしますが、高いエネルギー消費と採掘難易度の上昇を招きます。
ビットコインの供給量と半減期メカニズム
ビットコインの供給量は2,100万枚に厳密に制限されており、絶対的な希少性を持ちます。約4年ごとに「半減期」イベントが発生し、マイナーへのブロック報酬が半分になり、新しいビットコインの生成が遅くなります。これによりビットコインのインフレ抑制特性が強化され、長期的な価格上昇の主要な要因となります。2024年末時点で、1,970万以上のビットコインが採掘されています。
価格の推移と市場への影響
ビットコインはほとんど価値がない状態で始まり、2021年には$20,000 in 2017 and hitting new highs above $60,000に達しました。極端な価格変動を経験しており、有名な「ビットコインピザデー」のように、初めて商業利用された記念日もあります。過去にはバブルや詐欺と呼ばれたこともありますが、一般層や機関投資家の採用拡大により、時価総額は1兆ドルを超えました。
ビットコイン投資の理由とリスク
インフレヘッジ&価値の保存手段:供給量の固定と半減期イベントにより、ビットコインはデジタルゴールドであり、潜在的な安全資産となります。 高い流動性:BTCは主要取引所で取引されており、ポートフォリオへの組み入れが容易です。 分散化と自律性:特定の主体による管理を受けず、ユーザーは資産を完全にコントロールできます。 技術的・規制上のリスク:高いボラティリティ、規制の不透明さ、マイニングによる環境問題、決済手段としての利用制限。
懐疑的な見解と代替的視点
革命的な技術であるにもかかわらず、ビットコインの決済手段としての効率は低く、規制リスクも依然として大きいです。一部の専門家は、ビットコインを安定した価値の保存手段というより、投機的資産と見なしています。投資家は、自身のリスク許容度を慎重に評価する必要があります。

#2026年比特币行情展望 Got the birth chart of Bitcoin, but it's hard to tell if it's real or fake. 🧐The day master Wu Earth was born in the cold winter month of Zi, a scene of ice封——water flows fiercely, wood clashes with it, and metal is losing strength. This chart is inherently weak, and the core issue is clear: coldness plus weakness.
How to save it? Fire. Fire is the first救星 for this chart——dispelling寒冷, resolving凶煞, and accumulating vitality, all relying on it.
In 2026, Bing Wu, what is this? The Heavenly Stems and Earthly Branches are in the same气, a year of blazing火 covering the sky. For Bitcoin’s chart, it’s a once-in-a-decade reversal opportunity. Suddenly, in winter, spring flames arrive, and the根本之寒 is completely melted.
But don’t celebrate too early. The conflict between Zi and Wu means one thing——wealth luck will be like a roller coaster, with sharp ups and downs. On the surface, it looks prosperous, but beneath the water,暗流涌动, always hiding the possibility of a回调. 🤷
After saying so much, it feels like I haven’t really said anything.

#Strategy加码BTC配置  People often ask me, do ordinary retail investors still have a chance to make it in the crypto market? My answer is yes. But the premise is very important—don't approach investing with the mindset of traditional jobs.
The reality can be quite harsh. Salary growth always lags behind inflation, bank savings yields can't really combat rising prices, and good market sectors are becoming increasingly competitive. Frankly, the window for changing your fate through a job is closing.
But the crypto market is different. It doesn't care about your educational background, doesn't require connections, and has no participation barriers. This market only cares about two things: whether your thinking is clear and whether your operations are steady.
Unfortunately, most people stumble at the starting line. When prices rise, they itch to chase the high; when prices fall, they get scared and hesitate to buy the dip. In a bull market, they fear prices are too high; in a bear market, they worry it will keep falling. As a result, over a full cycle, they end up earning nothing, drained by constant regret and anxiety.
But there is always a small group of people who break this curse. They are not necessarily smarter or more skilled; some have just recently entered the scene and know little. But their common trait is—they can stay clear-headed amid market chaos and hold their positions steady in panic.
I’ve seen an example myself. A very ordinary guy, who started with only $500 in capital, no technical reserves, and no background support. But this guy has a super strong trait—stability.
While others are frantically chasing after prices during a surge, he remains unmoved; while others panic-sell, he researches, plans, and gradually adds to his position. When everyone dreams of getting rich overnight, he’s thinking about how to keep his position alive long enough to survive the next market cycle.
And now? This guy has indeed turned the tables. Not by luck from a margin call or a blow-up, but entirely by grasping the rhythm, sticking to patience, and understanding survival principles.
I’ve discovered a rule: opportunities in the crypto market never favor anyone specifically. The real determinant of winning or losing is who can prepare in advance and who dares to act decisively. Those watching from the sidelines are always chasing the trend, while those who have already laid out their plans are sitting on the rising train, waiting for the next surprise.
If you still haven’t figured out the rhythm, don’t know how to plan scientifically, and are clueless about risk management, then listen to my experience. Every pitfall I’ve stepped into can help you avoid detours.
What I can teach you isn’t some gambling secret, but the true way to survive: first, identify the big picture before acting; manage your positions calmly; have patience to endure the ups and downs of the cycle. Only then can you understand—making money is never just luck, but the result of a clever combination of structure and rhythm. The right mindset, combined with steady execution, is the key to breaking through in the crypto market.

#Strategy加码BTC配置  There is an old saying in the crypto circle: silence before a big move.
Look at popular coins like $DOGE, $PEPE, and $SHIB. On the surface, they seem calm, but in fact, market participants have already been secretly positioning themselves. Those with keen market intuition and quick reactions have already started increasing their holdings. By the time retail investors realize the opportunity, it’s often too late.
The current rally of Bitcoin follows a similar logic—those who enter now are just in the right place at the right time. The key is to be patient and wait for the wind to come.
