Blockchain technology has evolved dramatically since its early days, but the foundational principles and lessons from pioneers remain highly relevant. This article revisits a notable blockchain sharing session held in 2016, distilling key insights for newcomers. While rooted in historical context, the content is updated and optimized for today’s readers seeking to understand blockchain fundamentals, investment strategies, and how to navigate the space wisely.
Understanding the Blockchain Landscape
The blockchain world in 2016 was still in its adolescence—innovative, exciting, and undeniably chaotic. As one early advocate put it, the industry could be summed up in a single word: chaos. Many projects lacked substance, and hype often overshadowed real utility.
At the time, two dominant schools of thought emerged:
- Bitcoin Purists: Believed Bitcoin was the only legitimate blockchain application and dismissed alternatives.
- Blockchain Advocates: Took a broader view, exploring various blockchain use cases beyond digital currency.
The speaker of this session aligned with the latter group, advocating for a more open-minded approach. He emphasized that blockchain is a technology, while Bitcoin is just one application of it—specifically, a decentralized digital currency. Other platforms, like Ethereum, showcased blockchain’s potential as a foundation for decentralized applications (dApps), smart contracts, and new economic models.

This shift in perspective was so important that it led to the rebranding of a popular community group from Bitcoin Survival Guide to BCA Club—a move designed to encourage exploration beyond Bitcoin alone.
A key takeaway: blockchain is most valuable when applied to problems requiring large-scale trust solutions. If a project doesn’t address a real trust issue—like transparency in supply chains, ownership verification, or censorship-resistant transactions—it may not need blockchain at all.
The Role of BCA Club in Shaping Investors
BCA Club wasn’t created as a place for quick trades or price speculation. Instead, it focused on two core missions:
- Developing competent blockchain asset investors
Through education and curated discussions, members learned to evaluate projects based on fundamentals—not rumors or price pumps. - Sharing in the long-term growth of the blockchain ecosystem
Rather than chasing short-term gains, the club encouraged holding quality assets and participating in network development.
This philosophy remains vital today. In an industry flooded with noise, having a community that values research, patience, and critical thinking can make all the difference.
Exploring Early Blockchain Assets
One of the most valuable parts of the session was the breakdown of early blockchain-based digital assets available on platforms like Yunbi Network (a now-defunct exchange). These projects illustrated the diversity of blockchain applications even in 2016.
Bitcoin (BTC)
As the first cryptocurrency, Bitcoin dominated the market by capitalization and adoption. It functioned primarily as digital money—secure, scarce, and decentralized.
Ethereum (ETH)
More than just a currency, Ethereum introduced a programmable blockchain. Developers could build decentralized apps (dApps) and issue new tokens using smart contracts. Projects like DGD and 1SŦ were built on this foundation.
DGD (DigixDAO)
DGD represented ownership in DigixDAO, which issued DGX—a token backed by physical gold. Every transaction fee generated by DGX usage was distributed to DGD holders, creating a dividend-like model. With a fixed supply of 2 million tokens, scarcity added to its appeal.
SC (SiaCoin)
Sia offered decentralized cloud storage. Users could rent out unused hard drive space and get paid in SC. Files were encrypted and split across multiple nodes globally, enhancing security. Notably, the system was already functional—proof that blockchain could power real-world services.

1SŦ (FirstBlood)
A pioneering example of blockchain in gaming, FirstBlood enabled peer-to-peer esports betting. Players wagered tokens on matches, with outcomes verified by randomly selected, reputation-scored judges. This ensured fairness without centralized oversight.
ZEC (Zcash)
Focused on privacy, Zcash used zero-knowledge proofs (zk-SNARKs) to enable fully anonymous transactions—a feature unmatched by most other cryptocurrencies at the time. For users prioritizing financial privacy, Zcash offered a compelling alternative to Bitcoin’s transparent ledger.
The Bitcoin Scaling Debate
One of the most contentious issues in 2016 was Bitcoin’s scalability problem.
Bitcoin’s blockchain could handle only about 3 transactions per second (TPS), with each block limited to roughly 1,800 transactions. In contrast, traditional payment networks like Visa processed tens of thousands of TPS globally.
With only around 94.6 million transactions possible annually on Bitcoin—compared to Visa’s 92 billion in 2015—it was clear that without changes, Bitcoin couldn’t function as a global payment system.
Everyone agreed: Bitcoin needed to scale.
But disagreement arose over how:
- Some pushed for larger blocks (increasing on-chain capacity).
- Others advocated off-chain solutions like the Lightning Network.
- Still others supported alternative consensus mechanisms or sidechains.
These debates weren’t just technical—they involved economic incentives, mining power distribution, and governance philosophies. The lack of consensus led to prolonged conflict, eventually resulting in hard forks like Bitcoin Cash.
The takeaway? Even foundational technologies face growing pains. Scalability remains a central challenge across blockchains today—from Ethereum to Solana—proving that these early discussions were ahead of their time.
How Newcomers Can Avoid Common Pitfalls
For those entering the space, the session offered timeless advice:
Avoid Leverage Trading
Exchanges have full visibility into user positions. In volatile markets, leveraged trades often end in forced liquidations—especially during flash crashes or coordinated movements.
Steer Clear of "Guaranteed Return" Schemes
Promises of fixed returns in Bitcoin or other crypto assets are red flags. Due to extreme price volatility, no legitimate platform can reliably pay fixed interest in crypto without taking unacceptable risks.
Invest with Time and Capacity
True wealth in blockchain comes from time in the market, not timing the market. Use idle funds—money you don’t need短期内—and hold through volatility. Emotional decisions based on short-term swings lead to buying high and selling low.
Choose Projects Wisely
Thousands of blockchain projects exist; most fail. Evaluate them by asking:
- What real-world problem does it solve?
- Does it genuinely require blockchain?
- Is there a working product or just hype?
Projects like Sia and Digix stood out because they had functional applications—not just whitepapers.
Secure Your Keys
Never reuse passwords across accounts. Use strong password managers like 1Password. Most losses in crypto stem from poor security practices—not exchange hacks.

Frequently Asked Questions
Q: Is Bitcoin still the best cryptocurrency today?
A: While Bitcoin remains the most recognized and secure digital asset, newer blockchains offer advantages in speed, functionality, and use cases. Bitcoin excels as digital gold; others serve as platforms for innovation.
Q: Should beginners invest in altcoins?
A: Only after understanding the risks. Start with established projects that have clear use cases, active development teams, and real adoption.
Q: What makes a blockchain project trustworthy?
A: Transparency, open-source code, real-world utility, and community governance are strong indicators. Avoid anything promising unrealistic returns.
Q: How important is decentralization?
A: Critical. The core value of blockchain lies in reducing reliance on centralized authorities. Projects that concentrate control undermine this principle.
Q: Can blockchain work without cryptocurrency?
A: Some enterprise blockchains do—but public, permissionless networks rely on crypto incentives to secure the network and align participant behavior.
Q: How do I stay safe in crypto?
A: Use hardware wallets for large holdings, enable two-factor authentication, avoid sharing private keys, and never click on suspicious links.
Final Thoughts
Though this session took place years ago, its insights remain remarkably relevant. The core principles—evaluating real utility, avoiding hype, securing assets, and thinking long-term—are more important than ever in today’s complex digital asset landscape.
As blockchain continues to mature, those who focus on fundamentals will be best positioned to benefit from its transformative potential.
