I’m not going to tell you I can call market tops. Nobody can, and anyone claiming otherwise is selling something.
What I can tell you is what I notice in the weeks before crypto has historically peaked — the patterns that show up again and again across cycles. I’ve watched these signals play out in 2013, 2017, and 2021. They’re not predictive on their own, but when multiple of them show up together, I slow down my buying.
Not panic. Not selling everything. Just slowing down.
This is the pattern recognition I’ve developed after 10+ years of watching this market do the same stupid things over and over with slightly different costumes each time. If you’re currently considering a large crypto purchase and several of these look familiar, it’s worth pausing to ask whether you’re buying the opportunity or the hype.
TLDR
- These 7 signals don’t predict a top — they indicate the market may be in late-cycle euphoria where risk/reward for new buyers deteriorates.
- Multiple signals together carry more weight than any single one. One sign is noise; four or five at once is a pattern.
- My response is always the same: slow down new buys, don’t exit core positions, and wait for the cycle to normalize.
Why Market Tops Look Obvious in Hindsight and Invisible in Real Time
Before the list, it’s worth understanding why these signals are hard to act on even when you can see them.
When crypto is near a top, everything feels like it’s working. Price is up. Your portfolio looks great. The news is bullish. The smart people on Twitter are explaining why this cycle is different. New investors are pouring in. Every dip gets bought. The FOMO is real — if you’re not buying, you’re leaving money on the table.
This is the cognitive trap. The signals below are most visible precisely when the market feels best. Acting on them requires selling (or slowing buying) when momentum is strongest and sentiment is most positive. That goes against every instinct.
I’ve been early calling caution before peaks, and I’ve ignored signals and overstayed positions. Both have happened. The point of this list isn’t a trading system — it’s a checklist to run when you’re feeling the urge to add significant new money to crypto.
Sign 1: Mainstream Media Saturation
When Bitcoin is on the cover of Time magazine, or the New York Times is running weekly crypto profiles, or CNBC is dedicating hourly segments to which altcoin is up 300% this week — that’s a signal.
This isn’t anti-media cynicism. It’s simple market mechanics: media coverage of an asset follows price. Journalists write about it because readers are interested. Readers are interested because they’ve seen gains or heard about gains from friends. Media saturation reflects that retail attention has peaked, not that the fundamental thesis just got proven.
I distinctly remember the magazine cover jinx playing out in late 2017 and again in late 2021. By the time mainstream outlets are publishing guides for grandmothers on how to buy crypto, the pool of new buyers who haven’t already entered is getting thin.
To be clear: mainstream coverage isn’t always a top signal. Ongoing, measured coverage of crypto as an asset class is just normal. The signal is saturation — the feeling that you can’t open a newspaper or turn on financial TV without seeing a crypto story.
Sign 2: Everyone’s Cousin Is Asking About Crypto
I call this the Dinner Table Test. When people who have never expressed interest in investing start asking you about crypto at family gatherings, work events, or social settings — pay attention.
In late 2017, my aunt asked me how to buy Bitcoin at Thanksgiving. She had never talked about investing in her life. In late 2021, my dentist asked about Ethereum during a cleaning. These aren’t insults to these people — they’re just not typically early-stage investors. By the time investing ideas reach mainstream social conversation, they’ve already been well-discovered.
This isn’t to say latecomers never make money. Sometimes they do. But the risk/reward profile of an asset changes significantly when mass retail awareness has been achieved. Early adopters absorb the risk and capture most of the gain; retail wave buyers often arrive late and catch the reversal.
The corollary sign: if strangers on public transit are talking about their portfolio, or you see crypto ads on bus stops and billboards — same signal, different medium.
Sign 3: Altcoin Mania
Bitcoin typically leads a cycle. Then Ethereum runs. Then altcoins start running — including ones with no clear use case, no revenue, and sometimes no actual product.
The “alt season” isn’t inherently a top signal by itself. It’s a normal part of crypto cycles. What is a signal is the quality of what’s running. When random meme coins are up 50x in a week, when nobody can explain what a project does but the chart looks amazing, when new tokens are being created and immediately pumping — that’s late-cycle speculative mania.
I watched this in 2017 with ICOs (initial coin offerings): projects raising tens of millions of dollars with nothing but a whitepaper and a Telegram group. I watched it again in 2021 with DeFi tokens, NFT projects, and meme coins (DOGE, SHIB). The attention fragmented from quality assets to whatever was running.
When attention and capital are flowing into low-quality assets at high velocity, the overall risk of the market has increased. The same speculative energy that pumped your Bitcoin also pumped assets with zero fundamental value — and those will flush first and hardest, often pulling Bitcoin with them.
Sign 4: Google Trends Spike
Search interest in “buy bitcoin” or “how to invest in crypto” on Google Trends is a real signal. It’s democratized sentiment data.
Historically, Google search interest for “bitcoin” has spiked near major tops:
- December 2017: search interest hit near-peak levels as Bitcoin approached $20K
- November 2021: similar spike as Bitcoin broke through previous ATH toward $69K
The mechanic is similar to the cousin signal: peak search interest means peak discovery. The people who were going to search for how to buy crypto have already searched. The organic demand side of the equation is largely exhausted at that moment.
You can check this yourself for free. Go to Google Trends, search “bitcoin,” and look at the 5-year chart. The spikes are obvious and they line up with documented market peaks. It’s not a precise timing tool, but it’s a useful confirmation signal when other indicators are also elevated.
Sign 5: Open Interest in Futures at Extremes
This one is more technical but important. Open interest measures the total value of outstanding futures and options contracts that haven’t been settled.
When open interest in Bitcoin perpetual futures is at all-time highs, it means the market is extremely leveraged. That leverage cuts both ways: it accelerates moves up, and it accelerates moves down. When prices correct, forced liquidations create cascades — futures traders get margin-called, their positions close automatically, that selling pressure moves price down further, triggering more liquidations.
November 2021 had record open interest in Bitcoin perpetuals before the peak. The subsequent crash saw billions in liquidations that accelerated the move.
I don’t trade futures. But I watch open interest as a market structure indicator. When it’s extremely elevated, I know the market is fragile — small moves can trigger large forced selling events. This doesn’t mean the top is in, but it means any correction that does come will be sharper and faster than in a less-leveraged environment.
You can track this on exchanges like Binance or through data platforms like CoinGlass.
Sign 6: Celebrity and Brand NFT Launches
When Pepsi, McDonald’s, Adidas, and a dozen celebrities you haven’t thought about since the 2000s are launching NFT collections — stop adding new money to the market.
I’m being a little glib, but the underlying signal is real: when established brands and personalities launch crypto products, they’re following capital and attention that already peaked among early adopters. The marketing timeline for a major brand to approve, develop, and launch an NFT project means they started planning it months earlier, when the market was already elevated.
The 2021 NFT boom saw everyone from Paris Hilton to Snoop Dogg launching projects. McDonald’s did an NFT giveaway. The NBA launched Top Shot. These are lagging indicators of mainstream acceptance, which in speculative assets means late-cycle.
This signal is also useful as a cultural marker: when crypto has reached the point where corporate marketing departments see it as a brand alignment opportunity, the risk premium has changed fundamentally from when it was a niche technology curiosity.
Sign 7: Exchange App Tops the App Store
This one is quantifiable and specific: Coinbase hit the #1 spot in the iOS App Store in November 2021. Bitcoin peaked at approximately $69,000 shortly after.
In December 2017, crypto exchange apps dominated App Store charts as Bitcoin hit $20,000.
Peak app store ranking for exchange apps means peak retail onboarding. When millions of people are downloading Coinbase, Robinhood Crypto, or Kraken in a single week, it means mass retail participation has arrived. The same people who saw crypto in the news (Sign 1), heard their cousin talking about it (Sign 2), and Googled how to buy it (Sign 4) are now downloading apps and executing.
That’s the final stage of the retail adoption wave. At the top of an App Store chart, the addressable new buyer pool is, by definition, near exhaustion.
How I Use These Signals Together
None of these by themselves make me do anything. I see mainstream media coverage of crypto even in boring sideways markets. Google Trends for Bitcoin spikes during every major news event. A celebrity NFT launch in a bear market doesn’t mean anything.
The signal is convergence. When I’m checking off four or five of these simultaneously, the risk profile of new buys has changed.
My actual behavioral response:
1. Pause any planned above-baseline buys. My regular DCA might continue on schedule, but I’m not adding extra positions.
2. Review my allocation. If crypto has grown to over 25% of my portfolio alongside these signals, I’ll start thinking about a trim.
3. Don’t exit core positions. I’ve held BTC since 2014 through three bear markets. I’m not going to panic-sell based on vibes. But I’m also not adding to a potentially extended position.
4. Wait for normalization. These signals reverse. Fear & Greed goes back to neutral. Google Trends declines. Cousins stop asking. The market creates the next entry opportunity.
What I’ve learned the hard way: the signals were present and I acted on some of them and ignored others. In 2017, I sold too early (before the real parabolic phase). In 2021, I stayed in the DCA rhythm a bit longer than I should have given how many of these signals were present. Neither decision was catastrophic. Having the framework helped me not do something really stupid in either direction.
What These Signs Don’t Mean
I want to be explicit: none of this is a prediction. Crypto has surprised me to the upside more times than I expected. What feels like a top can turn into another 3x. The November 2021 peak looked like a top to many people in October 2021, and they missed a significant run.
These signals shift the probability distribution. They don’t determine the outcome.
If you’re holding long-term with a 5-10 year horizon, individual cycle tops matter much less. You’ll ride through them. What they matter for is:
- Sizing decisions for people actively allocating
- Expectation-setting for people entering new positions
- Reducing the chance of catastrophically over-investing near a cycle peak
The worst outcome isn’t missing some upside by being cautious. The worst outcome is putting in a significant lump sum near a top, watching it drop 70%, and panic-selling at the bottom. If these signals help you avoid that, they’ve done their job.
FAQ
What are the most reliable signs of a crypto market top?
No signs are perfectly reliable, but the highest-conviction signals I track are: exchange apps topping the App Store, open interest in futures at all-time highs, and MVRV ratio above 3.5. These have been present near every major Bitcoin top.
How do I know if we’re in altcoin mania?
When tokens with no clear utility or revenue are 10-50x in weeks, when new projects are being created and immediately pumping without fundamentals, and when your portfolio’s altcoin allocation has significantly outperformed Bitcoin — that’s alt season mania territory.
Does mainstream media coverage always mean a top?
No. Ongoing coverage of crypto is normal. The signal is saturation — where it’s impossible to avoid crypto content in non-crypto media contexts (general finance publications, mainstream TV, lifestyle coverage). One CNBC segment is not a signal. Hourly coverage across all channels is.
Should I sell when I see these signs?
That depends entirely on your time horizon and allocation. I don’t recommend selling core positions based on these signals alone. I recommend slowing down new buys and reviewing your overall allocation. For long-term holders, riding through cycle tops has historically been the right move — but entering new large positions at peak conditions has often been painful.
How do I check Google Trends for crypto?
Go to Google Trends, type “bitcoin” or “buy bitcoin,” set the timeframe to 5 years, and compare current search interest to prior peaks. The 2017 and 2021 peaks are clearly visible. If current interest is approaching those levels, that’s a meaningful data point.
I’ve watched these patterns cycle through at least three major bull markets. The costumes change — ICOs in 2017, DeFi and NFTs in 2021, whatever the next cycle brings. The underlying human behavior doesn’t change nearly as much as the participants think it does.
Pay attention to the signs. You don’t need to predict the future. You just need to be a little more careful when the evidence suggests the market is being irrational in your favor.
