Tools by job, not by brand
The crypto tool landscape changes constantly. Products launch, merge, add subscriptions or disappear, so a list of names would soon be stale. A more durable approach is to think in categories: each answers a different question, and most people need only a few of them. This article surveys the categories, what they are for and what to watch out for. It does not endorse any product.
Whatever you use, remember that tools describe markets; they do not predict them. Cryptocurrency prices are volatile, you can lose all you invest, and nothing here is financial advice.
Price trackers and market data sites
These are the “front page” of crypto: websites and apps that list coins with their price, market capitalization, volume and recent percentage changes.
Good for: quickly checking a price, comparing sizes of assets, seeing historical price data and finding basic facts about a coin such as supply.
Watch out for:
- Prices are usually blended from several venues. How that is done varies, as explained under price aggregation.
- Rankings by market capitalization depend on supply figures that are not always straightforward, a point covered under circulating supply and fully diluted valuation.
- Reported volume may include activity of questionable quality.
- Different sites can show slightly different figures at the same moment.
Charting platforms
These tools draw detailed charts with many timeframes, drawing tools and indicators. Some are built into exchanges, while others are independent services that pull data from many venues.
Good for: studying price history, testing how an indicator looks on past data, marking levels and saving layouts. Reading what they display is the subject of the guides on chart analysis and candlestick charts.
Watch out for: the pull of complexity. A screen with a dozen overlapping indicators looks rigorous but is often redundant. Free tiers may limit the number of indicators or the history available. Check which exchange’s data a chart is using before comparing it with another.
Screeners and scanners
A screener filters a large list of assets by criteria such as price change, volume or market capitalization. Some work on price-based conditions, such as which coins have risen the most over a week, while others filter by fundamentals.
Good for: narrowing a long list to a few items to research, or seeing what is moving.
Watch out for: a screener’s output is a starting point, not a recommendation. Lists of the biggest movers tend to be dominated by small, thinly traded assets where price moves are easy to cause, and where scams and pump and dump schemes are more common. A coin appearing on a list says nothing about whether it is sound.
On-chain dashboards
These services present blockchain data in charts: active addresses, transaction counts, exchange balances, holder distribution and valuation ratios. The reasoning behind such measures is introduced in the article on on-chain analysis.
Good for: seeing network activity and holder behavior that price charts do not show.
Watch out for: definitions differ between providers, address labels are estimates, and many of the most popular charts sit behind paywalls. Always read how a metric is defined before relying on it. The caveats are discussed in more detail under on-chain limitations.
Derivatives and market-structure data
Dashboards in this group display funding rates, open interest, liquidations and positioning, which describe how leveraged traders are placed. Background on these is found in the articles on funding rate and open interest.
Good for: gauging how crowded leveraged positioning may be, and understanding why certain sharp moves happened.
Watch out for: the figures cover only the venues a provider tracks, and reading them as signals invites overconfidence.
Portfolio trackers
Portfolio trackers record what you hold and show its value over time, sometimes by connecting to exchange accounts or reading public wallet addresses.
Good for: keeping a single view of holdings spread across several places and keeping records that help with tax reporting. The general concepts are in the article on tax concepts.
Watch out for: connecting a tracker to an exchange should use read-only access keys, never keys that allow trading or withdrawals. Be careful about where you enter any information, as fake tracker sites and apps are used by scammers. Link a wallet address only if you are comfortable with what that reveals about your holdings.
News, alerts and calendars
News aggregators, social feeds, price alert apps and event calendars help you follow developments. They save time, but they also add noise and can encourage reacting to every headline. Social posts in particular can be promotional or misleading, a theme examined under social media influence. A small number of trusted, varied sources is usually better than a flood.
Choosing and using tools sensibly
- Start with the question. Decide what you want to know, then pick the category that answers it.
- Cross-check important figures. If a number matters to a decision, confirm it from a second source.
- Understand the data source. Know which exchanges or chains a tool covers and how often it updates.
- Protect your accounts. Use unique passwords and two-factor authentication, grant minimal permissions and be wary of unsolicited links or browser extensions.
- Watch the cost. Subscriptions add up, and paying more does not make a tool’s conclusions more accurate.
- Keep it small. Two or three tools used well usually serve better than a dozen opened and ignored.
Tools can organize information and save effort, but the judgment about what to do with that information remains yours, and it is subject to the same uncertainty as the market itself.
