Crypto for Advisors: Memecoins

Memecoins have been in the news lately, primarily driven by the launch of the President’s $Trump coin. Recently, the U.S. SEC clarified that, for the most part, memecoins are not securities as they don’t meet the Howey test. That doesn’t mean clients won’t be asking questions about these assets, though.
So in today’s crypto for advisors, Janine Grainger from New Zealand-based Easy Crypto provides a breakdown of what memecoins are, how they work and the risks associated with them.
Then, Kieran Mitha, a next-gen investor, answers questions about learning about memecoins in Ask an Expert.

Memecoins: Boom, Bust and Billion-Dollar Bets
On January 17, a new meme coin called $Trump was launched by the President-Elect. Its market value peaked at $14.5 billion within two days but soon crashed by two-thirds. Entities behind the coin reportedly made close to a cool $100 million in trading fees in under two weeks (and even more from liquidations). Yet, hundreds of thousands of everyday investors lost significant amounts of money. Meanwhile, in late 2024, when Trump announced a Department of Government Efficiency (DOGE), the cryptocurrency Dogecoin surged 150%, far outpacing bitcoin’s gains.
Moments like these have put meme coins firmly on the investment radar. However, fueled by hype rather than utility, they create both opportunities and risks for investors, and financial advisors need to understand their unique market dynamics, as high-net-worth clients may inquire about them despite their speculative nature.

What are memecoins?
Memecoins are cryptocurrencies that originate from internet culture, social media trends or jokes. Unlike bitcoin or ether, which, over time, have built a case for inclusion in a diversified portfolio, memecoins thrive on hype, community sentiment and celebrity endorsement. While they often start as a parody or joke, viral marketing and speculative trading can give them serious traction — although this is usually short-lived.
Why meme coins matter
Memecoins have gained mainstream visibility due to their cultural relevance and potential for outsized short-term gains. High-profile figures like Elon Musk have fueled rallies with a single tweet, driving speculative interest. But while traders are drawn to the possibility of overnight riches, meme coins are high-risk assets with unpredictable price swings.
The price of meme coins can skyrocket or collapse within hours, leading to massive gains or total losses, such as ‘Fartcoin,’ a joke token that hit a $2.2 billion market cap purely through viral appeal before plummeting as early investors exited. Platforms like Pump.fun amplify this speculation by enabling users to create and trade meme coins with minimal technical knowledge. This has led to a flood of short-lived tokens that reinforce the market’s high-risk nature.
But are they legal?
Ironically, the Securities and Exchange Commission’s regulatory stance has helped memecoins thrive. While utility-driven crypto faces scrutiny and legal hurdles, memecoins operate in a grey area as they make no promises of financial returns. This has fuelled their proliferation.
The dark side: rug pulls and scams
Unfortunately, memecoins are a breeding ground for ‘pump-and-dump‘ schemes, where influencers hype a token to drive up its price and then cash out, leaving everyday investors with worthless holdings.
A recent example is viral internet personality Hailey Welch, who launched $HAWK after online infamy. Within a day, the coin’s market cap neared half a billion dollars before collapsing and sparking fraud accusations. Similarly, Argentina’s President Javier Milei inadvertently triggered a scandal when he promoted $LIBRA, which also surged and crashed, leaving him open to allegations of market manipulation. These incidents highlight why meme coins are often considered cryptocurrencies with little intrinsic value or long-term viability.

Memecoin investment considerations
Investors must remain cautious as many memecoins lack transparency. For those still interested, key risk factors include:
Liquidity: Low trading volumes lead to extreme price swings, making it hard to enter or exit positions.
Community sentiment: Social media drives price movements. Monitoring X (Twitter) and Telegram can provide market insights.
Tokenomics: Some memecoins drive scarcity, while others have an unlimited supply, diluting value over time.
Pump-and-dump risk: Aggressively marketed tokens with unrealistic promises often signal a short-term hype cycle rather than a sustainable investment.
Early entry vs. longevity: Getting in early can be lucrative, but the risk of a sudden crash is high. Some investors prefer established memecoins with strong communities over chasing the latest trend.
While memecoins can offer quick gains, their volatility and susceptibility to manipulation make them high-risk assets. Advisors should educate clients on their speculative nature and emphasize proactive risk management. Ultimately, memecoins are more akin to gambling than traditional investing.

Ask an Expert
Q: I see people on social media getting rich from memecoins…Can I do the same?
A: While some people have made significant profits from memecoins, it’s important to remember that social media often highlights success stories while ignoring the many who lose money. Memecoins are highly speculative, and their prices can be driven by hype, celebrity endorsements like Elon Musk, and market sentiment rather than solid fundamentals.
If you’re considering investing, approach it with caution. Timing is everything — many early buyers see significant gains, while those who buy in late often face losses when the hype fades or the rug is pulled. If you invest, treat it as a high-risk bet rather than a guaranteed path to wealth. Never invest more than you can afford to lose, and always do your own research before making any decisions.
Q. What role does community play in the success of a memecoin?
A: Community is the backbone of any successful memecoin and supports the overall sentiment towards the project. Unlike traditional investments, where value is often tied to revenue or utility, memecoins thrive on social media presence, viral trends, and grassroots enthusiasm. A strong, engaged community can drive adoption and keep a project relevant, but without sustained interest, even popular memecoins can fade quickly. Before investing, check how active the community is on platforms like X, Discord, and Reddit.
Q: How can I learn about memecoins before investing?
A: The most effective method to acquire knowledge regarding memecoins is through thorough research and active participation in the community. Commence by following reputable cryptocurrency news outlets, examining whitepapers, and engaging with forums such as Twitter, Reddit, and Discord, where communities actively discuss projects in real time. Consider factors such as the project’s website, roadmap, developer engagement, and tokenomics.
It is also crucial to comprehend the risks involved — memecoins are frequently characterized by high speculation; therefore, familiarizing oneself with market trends, trading strategies, and potential scams can assist you in making well-informed decisions. Do not depend solely on hype or social media influencers; conducting your due diligence is essential.

Is Ethereum’s DeFi Future on L2s? Liquidity, Innovation Say Perhaps Yes

Ethereum is in the midst of a paradox. Even as ether hit record highs in late August, decentralized finance (DeFi) activity on Ethereum’s layer-1 (L1) looks muted compared to its peak in late 2021. Fees collected on mainnet in August were just $44 million, a 44% drop from the prior month.
Meanwhile, layer-2 (L2) networks like Arbitrum and Base are booming, with $20 billion and $15 billion in total value locked (TVL) respectively.
This divergence raises a crucial question: are L2s cannibalizing Ethereum’s DeFi activity, or is the ecosystem evolving into a multi-layered financial architecture?
AJ Warner, the chief strategy officer of Offchain Labs, the developer firm behind layer-2 Arbitrum, argues that the metrics are more nuanced than just layer-2 DeFi chipping at the layer 1.
In an interview with CoinDesk, Warner said that focusing solely on TVL misses the point, and that Ethereum is increasingly functioning as crypto’s “global settlement layer,” a foundation for high-value issuance and institutional activity. Products like Franklin Templeton’s tokenized funds or BlackRock’s BUIDL product launch directly on Ethereum L1 — activity that isn’t fully captured in DeFi metrics but underscores Ethereum’s role as the bedrock of crypto finance.
Ethereum as a layer-1 blockchain is the secure but relatively slow and expensive base network. Layer-2s are scaling networks built on top of it, designed to handle transactions faster and at a fraction of the cost before ultimately settling back to Ethereum for security. That’s why they’ve become so appealing to traders and builders alike. Metrics like TVL, the amount of crypto deposited in DeFi protocols, highlight this shift, as activity is moved to L2s where lower fees and quicker confirmations make everyday DeFi far more practical.
Warner likens Ethereum’s place in the ecosystem to a wire transfer in traditional finance: trusted, secure and used for large-scale settlement. Everyday transactions, however, are migrating to L2s — the Venmos and PayPals of crypto.
“Ethereum was never going to be a monolithic blockchain with all the activity happening on it,” Warner told CoinDesk. Instead, it’s meant to anchor security while enabling rollups to execute faster, cheaper and more diverse applications.
Layer 2s, which have exploded over the last few years because they are seen as the faster and cheaper alternative to Ethereum, enable whole categories of DeFi that don’t function as well on mainnet. Fast-paced trading strategies, like arbitraging price differences between exchanges or running perpetual futures, don’t work well on Ethereum’s slower 12-second blocks. But on Arbitrum, where transactions finalize in under a second, those same strategies become possible, Warner explained. This is apparent, as Ethereum has had fewer than 50 million transactions over the last month, compared to Base’s 328 million transactions and Arbitrum’s 77 million transactions, according to L2Beat.
Builders also see L2s as an ideal testing ground. Alice Hou, a research analyst at Messari, pointed to innovations like Uniswap V4’s hooks, customizable features that can be iterated far more cheaply on L2s before going mainstream. For developers, quicker confirmations and lower costs are more than a convenience: they expand what’s possible.
“L2s provide a natural playground to test these kinds of innovations, and once a hook achieves breakout popularity, it could attract new types of users who engage with DeFi in ways that weren’t feasible on L1,” Hou said.
But the shift isn’t just about technology. Liquidity providers are responding to incentives. Hou said that data shows smaller liquidity providers increasingly prefer L2s where yield incentives and lower slippage amplify returns. Larger liquidity providers, however, still cluster on Ethereum, prioritizing security and depth of liquidity over bigger yields.
Interestingly, while L2s are capturing more activity, flagship DeFi protocols like Aave and Uniswap still lean heavily on mainnet. Aave has consistently kept about 90% of its TVL on Ethereum. With Uniswap however, there’s been an incremental shift towards L2 activity.
Another factor accelerating L2 adoption is user experience. Wallets, bridges and fiat on-ramps increasingly steer newcomers directly to L2s, Hou said. Ultimately, the data suggests the L1 vs. L2 debate isn’t zero-sum.
As of September 2025, about a third of L2 TVL still comes bridged from Ethereum, another third is natively minted, and the rest comes via external bridges.
“This mix shows that while Ethereum remains a key source of liquidity, L2s are also developing their own native ecosystems and attracting cross-chain assets,” Hou said.
Ethereum thus as a base layer appears to be cementing itself as the secure settlement engine for global finance, while rollups like Arbitrum and Base are emerging as execution layers for fast, cheap and creative DeFi applications.
“Most payments I make use something like Zelle or PayPal… but when I bought my home, I used a wire. That’s somewhat parallel to what’s happening between Ethereum layer one and layer twos,” Warner of Offchain Labs said.

Santander’s Openbank Starts Offering Crypto Trading in Germany, Spain Coming Soon

The digital banking arm of Spanish financial giant Santander Group, Openbank, opened cryptocurrency trading for customers in Germany, with plans to add its home market in the next few weeks.
The new service allows users to buy, sell and hold five popular cryptocurrencies: bitcoin (BTC), ether (ETH), litecoin (LTC), polygon (MATIC) and cardano (ADA), according to a press release. The cryptocurrencies are available alongside stocks, ETFs and investment funds.
Customers can trade without moving funds to an external platform, keeping all investments in one place under Santander’s umbrella, the bank said.
“By incorporating the main cryptocurrencies into our investment platform, we are responding to the demand of some of our customers,” said Coty de Monteverde, head of crypto at Grupo Santander.
The bank charges a 1.49% fee per transaction, with a 1 euro ($1.2) minimum, and does not include custody fees. The bank said it plans to add more cryptocurrencies and new features, such as crypto-to-crypto conversions, in coming months.
Santander Private Bank was back in 2023 making headlines when it started letting clients with accounts in Switzerland trade BTC and ETH. It selected crypto safekeeping technology firm Taurus for custody.
