2017 was a transformative year for cryptocurrency. The total market capitalization started around $18 billion in January and ballooned to over $600 billion by December — a staggering increase of more than 3,000%. This meteoric rise was driven by a confluence of factors: the initial coin offering (ICO) boom, surging retail interest, media frenzy, and the growing recognition of blockchain technology's potential.
Bitcoin, still the dominant force, saw its price climb from roughly $1,000 to nearly $20,000 by year-end. Ethereum established itself as the leading smart contract platform, enabling the ICO boom that gave rise to hundreds of new projects. Altcoins — many of which are now household names — experienced explosive gains, though many also faced sharp corrections.
For investors, 2017 was both exhilarating and perilous. Fortunes were made, but many also learned hard lessons about volatility, speculation, and the importance of fundamental research. This guide revisits that year not to reminisce, but to extract actionable insights that remain relevant for today's crypto participants.
By market capitalization, the top cryptocurrencies at various points in 2017 included a mix of established leaders and rising stars. The list below is based on data from December 2017, near the peak of the bull run.

Ethereum's smart contract capabilities fueled the ICO boom, where new projects raised billions of dollars by issuing their own tokens on Ethereum's platform. While many of these projects promised revolutionary applications, a significant number failed to deliver, and some were outright scams. This period highlighted the importance of due diligence and the risks of investing in unproven ventures.
Despite the rise of altcoins, Bitcoin remained the market leader throughout 2017. However, it faced scalability debates, leading to the Bitcoin Cash hard fork in August. The network congestion and high fees during the peak demand periods were early signs of the challenges that would later be addressed by Layer-2 solutions.
The term "top" in 2017 was largely driven by market capitalization, which was heavily influenced by hype, speculation, and ICO fundraising. However, from a practical standpoint, we can extract a framework for evaluating cryptocurrencies that applies then and now.
The following data illustrates the explosive growth and volatility of the 2017 market. While these figures are historical, they serve as a case study in market dynamics.
The total cryptocurrency market cap surged from approximately $18 billion in January 2017 to over $600 billion in December 2017. This growth was fueled by the ICO boom, with over $5 billion raised through token sales in 2017 — a massive increase from previous years.
The 2017 crypto market offers enduring lessons for investors and enthusiasts. Here are some of the most critical takeaways.
Many investors bought into ICOs based on hype alone, without understanding the technology, team, or tokenomics. As a result, they lost money when projects failed to deliver. Always research the fundamentals and avoid "shiny object" syndrome.
The extreme volatility of 2017 demonstrated that even the top assets can experience 30-50% drawdowns in days. Diversification across different projects and asset classes, along with position sizing, can help manage risk.
While many 2017 top coins have not recovered, Bitcoin and Ethereum have proven resilient over the long haul. This suggests that established, well-funded projects with active development have a better chance of surviving market cycles.
2017 saw numerous exchange hacks and scams. The mantra "not your keys, not your crypto" was reinforced as many users lost funds on centralized platforms. Self-custody became a priority for long-term holders.
This checklist remains valuable for evaluating any cryptocurrency, regardless of era.
The 2017 bull run attracted not only investors but also malicious actors. Security breaches were common, and many novice investors fell victim to phishing, fake ICOs, and exchange hacks.
The setting: In early 2017, an investor named Alex became interested in cryptocurrency after reading about Bitcoin's potential. With a moderate risk appetite, Alex allocated $5,000 to a diversified portfolio: 40% Bitcoin, 30% Ethereum, 20% Litecoin, and 10% smaller altcoins like NEO and IOTA.
The journey: By December, the portfolio had grown to over $50,000 — a tenfold increase. However, in January 2018, the market corrected sharply, and Alex's portfolio dropped to around $25,000. Despite the volatility, Alex held on, having done research and having a long-term belief in the technology.
The outcome: By 2020, some altcoins had lost significant value, while Bitcoin and Ethereum had recovered and eventually hit new highs. Alex learned the importance of taking profits, diversifying, and staying informed. The experience shaped a disciplined approach to future investments.
Lessons: The scenario illustrates the importance of a clear investment thesis, risk management, and emotional resilience. It also shows that not all top coins survive, so continuous evaluation is necessary.

The 2017 bull run was a breeding ground for mistakes that many investors made. Recognizing these pitfalls can help you avoid them.

The top cryptocurrencies by market capitalization in 2017 included Bitcoin, Ethereum, Ripple (XRP), Litecoin, NEO, IOTA, Monero, Dash, and NEM. Bitcoin remained the dominant player, while Ethereum gained massive traction due to the ICO boom and smart contract capabilities.
2017 was a landmark year for cryptocurrency, with the total market cap surging from ~$18 billion to over $600 billion by December. Bitcoin reached nearly $20,000, and many altcoins saw exponential gains. However, the market was highly volatile and experienced sharp corrections.
Key drivers included the initial coin offering (ICO) boom, growing mainstream media attention, increased retail investor participation, advancements in blockchain technology (Ethereum smart contracts), and a general sense of speculative enthusiasm. Regulatory developments also played a role.
No. While some (like Bitcoin and Ethereum) have maintained relevance, many top 2017 coins lost substantial value or faded into obscurity. Projects that lacked clear utility, strong teams, or ongoing development struggled. This highlights the importance of fundamental analysis over hype.
Key lessons include: avoid FOMO, conduct thorough research, understand tokenomics, be wary of projects with vague roadmaps, diversify, take profits periodically, and recognize that past performance does not guarantee future results. The 2017 market also underscored the importance of security and self-custody.
You can use archival services like CoinMarketCap historical data, Wayback Machine for old web pages, and blockchain explorers to look at on-chain metrics from that era. However, not all data is perfectly preserved; cross-reference multiple sources.
Some did — Bitcoin as digital gold, Ethereum as a smart contract platform — while others were more speculative. Many ICO projects promised ambitious solutions but lacked proven technology or adoption. Evaluating use case viability was often challenging amidst the hype.
That depends on your investment thesis and the current state of each project. While some have grown significantly, others have declined. It's never too late to evaluate an asset based on its current fundamentals, but past performance is not a reliable predictor of future returns.
