This article shares my personal journey and evolving perspective on cryptocurrency and blockchain technology. From initial skepticism to deep understanding, I document how my views transformed through self-education and real-world exposure.
First Exposure to Bitcoin
My initial encounter with Bitcoin occurred during my university years. As a computer science student, I naturally came across emerging software technologies. I distinctly remember hearing about this "electronic currency" around 2012-2014, though the exact timeline remains fuzzy.
At that time, immersed in academic life, these concepts felt distant and abstract. I knew Bitcoin by name but made no effort to understand its underlying mechanics or potential implications. The technology remained an intriguing but unexplored curiosity during my college years.
Building Initial Understanding Through Articles
After graduating in 2014, I began actively following technology platforms like CSDN, 51CTO, and Open Source China to stay current with industry trends. Throughout 2014, I noticed increasing mentions of Bitcoin and blockchain in technical articles.
Initially, I skimmed past these pieces, but their persistent appearance signaled their growing importance. The articles frequently mentioned concepts like "halving," "mining," and "computing power" without providing substantial technical explanations. As someone drawn to pure technology rather than financial applications, I found myself more interested in blockchain's technical aspects than Bitcoin's monetary implications.
My key takeaways from this period included:
- Bitcoin was built on blockchain technology, representing its first successful application
- Many analysts considered blockchain the next major technological revolution
- The technology promised potential transformations across finance and social organization
- Blockchain offered decentralized, tamper-resistant data storage
- At its core, blockchain represented a chain-linked data structure or database
Despite recognizing the technology's potential, I remained skeptical about Bitcoin specifically, viewing it as speculative without inherent value.
The Phase of Confusion and Curiosity
Bitcoin and blockchain content continued appearing in my feeds, with stories about price surges and mining operations. Reports described people buying specialized computers for mining, and even internet cafes converting their entire operations to mining activities.
I found this phenomenon both puzzling and fascinating. My understanding of mining remained superficial—I knew it involved "earning" Bitcoin through computational work but couldn't comprehend why people would devote such resources to this activity. The entire ecosystem felt somewhat mysterious and slightly irrational during this period.
Shifting Perspectives Through Technical Sharing
In 2017, our technical manager presented a comprehensive分享 on Bitcoin and blockchain during a team meeting. He began with traditional financial systems, then detailed Bitcoin's implementation mechanics: how decentralization worked, how trust was established through public-private key cryptography, how transactions were packaged into blocks, and how new blocks joined the chain.
Most importantly, he addressed Bitcoin's value proposition directly. He noted the ongoing debate about whether Bitcoin represented pure speculation or genuine value, mentioning his personal investment of half a Bitcoin. His concluding remark—"The future remains uncertain"—struck me profoundly.
This presentation coincided with Bitcoin's 2017 bull market, revealing that technical professionals were seriously engaging with cryptocurrency markets. My dismissive attitude transformed into cautious curiosity. I considered purchasing a small amount of Bitcoin or experimenting with mining but unfortunately didn't follow through—a decision that delayed my serious engagement by four years.
Complete Transformation and Deep Dive
The pivotal moment arrived in February 2021, when a conversation with a new acquaintance challenged my investment perspective. After mentioning my traditional stock and fund investments, he dismissively referred to them as "conventional financial instruments."
His朋友圈 contained extensive content about blockchain, IPFS, and Filecoin, promoting Filecoin's mining opportunities and future value. What shocked me most was IPFS—a concept I'd encountered years earlier as a potential HTTP replacement—now appearing as a functional system rather than theoretical proposal.
This discovery generated numerous questions: Was IPFS actually operational? How did it relate to Filecoin? Was Filecoin another cryptocurrency like Bitcoin? Did it possess real value? Why did this person consider cryptocurrency superior to traditional investments?
Since Filecoin connected to IPFS—a tangible technological application—it seemingly had more inherent value than Bitcoin alone. However, being someone who only invests in what I understand, I committed to proper research before considering participation.
Systematic Learning Process
I began researching IPFS and Filecoin through various platforms including Baidu, Google, Bilibili, and YouTube. After establishing basic concepts, I purchased "IPFS Principle and Practice," which referenced blockchain concepts that required deeper understanding.
I then acquired several introductory books:
- "Blockchain Cryptography Consensus: Principles, Industry and Application"
- "Plain Talk About Blockchain"
- "Blockchain Development Guide"
The first book provided particularly comprehensive coverage, though all three lacked deep technical specificity. Following community recommendations, I obtained "Mastering Bitcoin: Programming the Open Blockchain" (Chinese edition: "精通区块链编程").
After thoroughly studying this text over one month, I experienced unprecedented intellectual revelation. The book answered my fundamental questions:
- Why is Bitcoin divisible?
- How are transactions secured against loss?
- What are the different wallet types and their characteristics?
- How are transactions created, packaged, and recorded?
- How are blocks structured and connected?
- How does mining actually work and what is its essential purpose?
- How does difficulty adjustment work and why is it necessary?
- What is the ultimate purpose of massive energy consumption in mining?
- What are mining cycles and how are halving events determined?
- How does decentralization create trust without government backing?
Profound Realizations
This learning journey led to several epiphanies:
I finally understood why Bitcoin represents a revolutionary invention regardless of one's perspective on its monetary value.
I comprehended why many consider blockchain technology the next technological frontier and information revolution.
I recognized why Satoshi Nakamoto was nominated for a Nobel Prize in Economics.
I understood why people steadfastly believe in Bitcoin—I had become one of those previously inexplicable believers.
I grasped the fundamental reasons behind the intense controversy surrounding Bitcoin and why opposing sides seem unable to reconcile their views.
Most importantly, I clearly recognized which direction represents the future trajectory of technological development.
