Coinbase CEO Brian Armstrong said on September 10 that bitcoin has bottomed for this cycle, even as BTC traded near $78,000 and 95 of the CoinDesk 100 tokens fell in a broad retreat. This guide explains what a call like that mechanically means, what stays unknown, and how to watch your bitcoin, altcoins and stocks in one view with price alerts that check every level once a minute.
What did Brian Armstrong actually say about a bitcoin bottom?
On September 10, Coinbase CEO Brian Armstrong said bitcoin (BTC-USD) has bottomed for the current cycle, even as the price sat near $78,000 during a broad crypto sell-off. His claim is a personal market view, not a data point that changes anything on-chain or on any exchange order book.
The backdrop matters. On the same day, 95 of the 100 tokens in the CoinDesk 100 index were in the red, so the retreat was market-wide rather than bitcoin-specific. A single executive calling a bottom does not put a floor under a price; the price is still set by buyers and sellers minute to minute.
We covered the original headline in more depth in our breakdown of what the Coinbase CEO bottom call means, and this piece focuses on how a holder can track the fallout rather than react to a forecast.
What does "bitcoin has bottomed" mechanically mean?
"Bottomed" means the lowest price of a cycle is already in and future prices will be higher, but that can only ever be confirmed in hindsight. Nobody, including an exchange CEO, can verify a bottom in real time because it is defined by prices that have not printed yet.
A few mechanical facts help separate the claim from the noise:
- A forecast is not a floor. Order books do not respond to opinions, only to bids and asks.
- Index-wide weakness means altcoins and bitcoin fell together, so diversification across tokens gave little cover on the day.
- Volatility cuts both ways. A move from $78,000 can extend in either direction, and past cycle lows do not obligate the next one.
None of this tells you what to do. It tells you what is known (the price fell), what is claimed (the low is in), and what is unknown (whether that claim holds).
How can you track bitcoin and altcoins alongside your stocks in one view?
You track crypto and equities together by holding them in a single multi-asset portfolio tracker rather than switching between a broker app and an exchange app. PortfolioTrackr puts BTC-USD, altcoins like ETH-USD and SOL-USD, and stocks such as AAPL or NVDA on one screen with one blended total.
Why a single view beats app-hopping
A single view beats app-hopping because your real exposure is the combination, not the pieces. If bitcoin is 30% of your net worth and your tech stocks add another 25%, a risk-off day hits both at once, and only a combined view shows that.
- See crypto and equity weightings side by side in one currency.
- Convert everything into any of 67 display currencies, so a Nairobi or London investor reads totals in their home currency.
- Track across 95 stock exchanges for the equity sleeve, from the New York Stock Exchange to frontier venues like the Colombo Stock Exchange.
You do not need to connect anything to start
Connecting a broker or exchange is optional on every plan. You can add positions by manual entry, voice, text, CSV import or a broker screenshot, so a cold wallet or an exchange PortfolioTrackr does not integrate with is never a blocker.
If you do want automatic syncing, PortfolioTrackr connects 35 brokers through the SnapTrade bridge plus three direct integrations, Alpaca, Bybit and Interactive Brokers. Our guide on connecting a brokerage account to a portfolio tracker walks through the flow step by step.
How do price alerts help you navigate crypto volatility?
Price alerts help by watching your levels for you, so you hear within a minute of a price you care about being reached instead of staring at charts through a sell-off. PortfolioTrackr checks every position and every watchlist level once a minute, around the clock, which suits a market like bitcoin that never closes.
What the alerts do and do not do
Alerts report status against your own levels. They do not tell you to buy or sell, and they do not generate signals. When a level you set is reached, the alert fires with a plain status update.
- Status reporting only: still below target, Target 1 reached, Target 2 reached, or stop-loss level reached.
- Cadence: you hear within a minute of your level being hit, and a recurring alert repeats for the same target at most once every five minutes.
- Watchlist alerts: a Pro and Lifetime feature, useful for tokens you follow but do not yet own, like a fresh altcoin listing.
So if you had set a level near where BTC-USD traded on September 10, PortfolioTrackr would have reported that the level was reached rather than deciding anything for you.
Which levels can you set for a name like bitcoin?
You can set upside targets and a stop-loss level for any position or watchlist name, defined by your own numbers. The tracker reports where price sits against those numbers; the numbers themselves are yours.
| Alert type | What it reports | Best for |
|---|---|---|
| Target 1 | Your first upside level reached | Positions you are watching climb |
| Target 2 | A second, higher level reached | Longer-term milestones |
| Stop-loss level | Your downside level reached | Managing exposure in a fast market |
| Watchlist level | A level hit on a token you do not own | New listings and altcoin ideas |
Because everything is checked once a minute, a level set on a Colombo-listed stock and a level set on ETH-USD are watched with the same cadence, which matters when equities and crypto move together on a risk-off day.
How should holders read a bottom call without acting on it?
Holders can treat a bottom call as one input to check their own situation, not as an instruction. Checking is not advice; deciding for you would be. A few things a holder can verify for themselves:
- Your exposure to the name and sector: what percentage of your total is bitcoin, and how much sits in correlated altcoins.
- Whether an alert is set: confirm you have levels defined so you hear within a minute rather than refreshing a price screen.
- How the position sits against your own targets: whether price is still below your Target 1 or has reached a level you predefined.

How does a multi-asset tracker compare to a broker or exchange app?
A multi-asset tracker beats single-venue apps because it shows your whole book, while a broker app shows only what is held there and an exchange app shows only crypto. If your bitcoin sits on one exchange, your ETH-USD on another, and your stocks at a broker, no single app sees the full picture.
- Broker app: strong for the equities held there, blind to outside crypto and other brokers.
- Exchange app: good for tokens on that venue, no view of your stocks or cold storage.
- PortfolioTrackr: one blended total across crypto and equities, in any of 67 currencies, with alerts on every level.

The bottom line
Armstrong's September 10 claim that bitcoin has bottomed is one executive's forecast, made while BTC-USD traded near $78,000 and 95 of the CoinDesk 100 fell. A bottom can only be confirmed later, so the useful response is to know your own exposure, not to act on a headline.
A single view of crypto and stocks, plus alerts that report your levels within a minute, lets you follow the volatility without living on a chart. PortfolioTrackr reports status against your numbers and leaves every decision to you.

Do bitcoin price alerts tell me when to buy or sell?
No. PortfolioTrackr alerts report status against your own levels, such as Target 1 reached or stop-loss level reached. They do not give buy or sell signals or advice. The levels are numbers you set yourself, and every decision stays with you.
Is it safe to trust a CEO calling a bitcoin bottom?
A bottom call is a forecast, not a floor, and order books respond only to actual bids and asks. A prudent approach is to check your own exposure to bitcoin and correlated altcoins and confirm your alerts are set, rather than acting on any single person's prediction.
