BTC Auditor

On-chain analysis with verifiable data

Free Bitcoin alerts, no signup

An alert when price, MVRV, NUPL, Fear & Greed or the funding rate crosses the number you choose. Delivered by Telegram or email. No paid plan, no card.

Looking at on-chain charts is easy, and plenty of sites publish them. What almost always sits behind a paywall is the other half: having something watch them for you and tell you. That's what this is.

The hard part isn't alerting — it's not over-alerting

A threshold alert written the obvious way is useless. Set “tell me when MVRV goes above 2.5” and let MVRV hover between 2.49 and 2.51, and you get one message per check — 72 a day. Within two hours you mute it, and then you miss the crossing that actually mattered.

So there are three controls, and none of them is optional or a paid-tier extra:

When the alert arrives it also carries the value’s historical percentile against the whole series: “22nd percentile — MVRV was higher on only 78% of days.” A number on its own doesn’t tell you whether it’s a lot or a little.

Just want to watch? Telegram channel, no signup

It automatically posts the crossings that matter on Bitcoin: MVRV in top or bottom territory, extreme fear and greed, and moves of more than 5% in 24h. If the market does nothing, the channel says nothing.

Or set up your own alert, with your threshold. It needs email confirmation before it activates; you can unsubscribe any time from the link in every message.

Advanced conditions

With a second condition, the alert fires only when both hold at once. For example, MVRV above 3 and Fear & Greed above 80: the classic cycle-top combination.

To receive alerts on Telegram: 1) open @btcauditor_bot and send it /start — Telegram doesn’t let a bot message you first; 2) message @userinfobot, which replies with your chat ID; 3) paste that number here.

All five are available for Bitcoin; MVRV and NUPL also for Ethereum. Every source is public and needs no API key, which is why this can be free rather than a trial with an expiry date.

Three alerts worth having set

These are not buy or sell recommendations. They're the crossings that historically marked a regime change, with the numbers verified against the full series since 2011.

Frequently asked questions

Is it really free?

Yes. No paid plan, no card, no cap on alerts. The site is supported by exchange affiliate links, which are labelled as such and optional.

How often is it checked?

Every 20 minutes. Price and funding are read live; MVRV and NUPL come from daily series, so their value changes once a day — asking for an MVRV alert “in 1h” would make no sense, which is why the form doesn't offer it.

What if it lands in spam?

It can, and it's better said up front than after the fact: the site has no custom domain yet, so email goes out from a shared domain with no reputation. Telegram is the recommended channel for exactly that reason: no spam filter, and it doesn't depend on any of this.

Do you store my data?

Your email and the condition you defined, nothing else. No tracking cookies, no browsing profile. Every message carries its unsubscribe link, and unsubscribing deletes the alert. See privacy (Spanish).

Is this financial advice?

No. It's an automated notice that one number crossed another number. What to do about it is each person's decision.

Understand the metrics before setting a threshold

Picking the number is half the work. Every metric has its own page with the full series, its historical percentile, and the cycles where it failed: MVRV · NUPL · realised price · MVRV Z-Score · Puell Multiple · Stock-to-Flow · Power Law · cycle tops.
