Most market sites pick a lane. Crypto outlets treat equities as someone else's problem; stock sites still write about digital assets as a curiosity. Yet a growing number of investors hold both, move capital between them, and need to understand how they relate. We built Market Capitalize for that reader: someone who wants to glance at Bitcoin and the S&P 500 on the same screen, look up a single coin or ticker in seconds, and run the numbers on a trade before committing real money.
Qué publicamos
Three things, kept deliberately simple:
- Datos de mercado en vivo. Continuously updated prices, market caps, 24-hour moves and charts across hundreds of cryptocurrencies and major US-listed stocks, with a combined markets view for seeing both at once.
- Herramientas gratuitas. A suite of calculators for profit and loss, position sizing, risk and reward, compounding, dollar-cost averaging and more. They run entirely in your browser — no sign-up, no account, no data collection.
- Explicaciones claras y sencillas. Context on how markets work, what the numbers mean, and how the same idea — liquidity, volatility, market capitalisation — shows up differently in crypto and equities. Start at our Learn hub.
Por qué cubrimos ambos mercados
Crypto and equities are usually presented as separate worlds, but the questions investors ask are strikingly similar. What is this asset actually worth? How big is it relative to its peers? How much could I lose if I am wrong? The vocabulary differs — market cap and circulating supply on one side, market cap and shares outstanding on the other; the Fear & Greed Index here, the VIX there — but the underlying logic rhymes. Covering both lets us draw those parallels honestly, and lets you keep one tab open instead of five. Our crypto vs stocks guide walks through where the two genuinely differ and where they only appear to.

No paywall sits in front of any of it, and we ask for nothing in return — no account, no card, no email required to read.
Independiente por diseño
We are not owned by an exchange, a brokerage, a fund or a token project. We do not take payment to cover, rank or recommend any asset. Some links on the site may be affiliate links, and we disclose that plainly in our affiliate disclosure — but commercial relationships never decide what we publish or how our data is presented. Our full position on independence and conflicts of interest is set out in our ethics policy.
Cómo trabajamos — con honestidad
We believe you deserve to know how the words and numbers on a page were produced. Market Capitalize is made by a small editorial and data team. We use software to gather and assemble live market data, and we use AI tools to help draft and structure some explanatory content. Every page is reviewed by a human editor before and after publication, and the editorial team is accountable for what appears here. We do not invent author identities or stock-photo "analysts" to seem larger than we are — published work carries a Equipo de Market Capitalize byline. You can read exactly how this works in our editorial guidelines and meet the team on our team page.
In practice, every explainer travels the same path before it reaches you:
- Datos recopilados. Live prices and statistics are pulled automatically from our named providers — never typed in by hand.
- Redactado. We research and structure the piece, using AI tools to help with a first draft where useful.
- Editado por un humano. An editor checks facts against primary sources, balances the framing and adds the right risk context.
- Published & accountable. It goes live under the Market Capitalize Staff byline, with the team responsible for it.
- Corregido si es necesario. If you spot a mistake, our política de correcciones gets it fixed and noted.
De dónde proceden nuestras cifras
Crypto prices, market caps and rankings come from CoinPaprika; seven-day sparklines from Binance; the Crypto Fear & Greed Index from Alternative.me; and US equity quotes and charts from Nasdaq. Data is cached briefly and may be slightly delayed. When a live figure is genuinely unavailable, we show nothing rather than a stale guess or a placeholder — we would rather a gap than a number you cannot trust. The full picture is in our data & methodology page.
No es asesoramiento de inversión. Everything on Market Capitalize is general information and education about cryptocurrencies and US-listed securities. It is not investment, financial, legal or tax advice, and we are not a licensed broker-dealer or investment adviser. Markets are volatile and you can lose money. Please read our full disclaimer.
