The blockchain is a public ledger. While individual wallets are anonymous, the flow of funds isn't. Every transaction is recorded, creating a trail of data that can be analysed to gauge market sentiment. This is called on-chain analysis, and it's how we can move beyond price charts to see what investors are actually doing with their coins.

The most fundamental metric is Exchange Net Flow. This simply tracks the total amount of a cryptocurrency, like Bitcoin, moving into and out of all exchange wallets.

• High Inflows: When a large volume of coins moves onto exchanges, it often signals intent to sell. Investors typically don't store their assets on exchanges long-term due to security risks. A deposit usually means a sale is imminent.
• High Outflows: Conversely, when coins move off exchanges into private wallets, it suggests accumulation. Investors are moving their assets into cold storage for holding, reducing the immediately available supply for sale. This is generally seen as a bullish signal.

Platforms like Glassnode and CryptoQuant are essential tools for tracking these flows in real-time.

Not all transactions are equal. A $100 trade doesn't impact the market, but a $100 million trade certainly does. Large holders, often called whales, can single-handedly shift market dynamics. That's why we need to pay special attention to their activity.

The Exchange Whale Ratio is a simple but powerful metric for this. It's calculated as the top 10 inflows to exchanges divided by the total inflows for that day. It tells us what percentage of the sell-side pressure is coming from the biggest players.

Price tells you what something is worth now, but it doesn't tell you if the market is over- or undervalued. To understand that, we need to know the collective cost basis of all holders. This is where the MVRV Ratio comes in.

The MVRV Ratio is the Market Value (current price x circulating supply) divided by the Realised Value. Realised Value, or Realised Cap, is calculated by valuing each coin at the price it last moved on-chain. Think of it as an approximation of what everyone paid for their coins.

A high MVRV ratio (often above 3.0 for Bitcoin) indicates that the average holder is in significant profit, which increases the likelihood of profit-taking and a market top. A ratio below 1.0 means the market is, on average, underwater. This can signal holder capitulation and a potential market bottom, as the incentive to sell at a loss diminishes.

The Realised Price itself (Realised Cap / Circulating Supply) acts as a powerful dynamic support and resistance level. When the market price dips below the Realised Price, it often signals a major bear market.

By combining these metrics, you can build a robust framework. You can use Exchange Net Flow and the Whale Ratio to gauge short-term sell pressure, while the MVRV Ratio and Realised Price help you understand where we are in the broader market cycle. It's a way to filter the noise and focus on the actions of the most influential players.
