Major Players and Cryptocurrency Prices: When Is It Normal Trading and When Is It Market Manipulation?

Large cryptocurrency transfers or sharp price swings often prompt speculation about market manipulation. When a large amount of bitcoin is moved to an exchange, for example, investors may expect a significant fall in the price. The transfer alone, however, does not mean that a sale has actually taken place.

Large investors can significantly influence cryptocurrency prices, but not every large trade constitutes manipulation. It is important to distinguish between ordinary trading activity and the deliberate creation of a false impression of supply or demand.

Who are crypto whales?

The term whale is used for investors or other entities that own large amounts of cryptocurrency. There is no single threshold, but for Bitcoin, for example, entities holding at least 1,000 BTC are sometimes regarded as whales.

It is important, however, to distinguish between a blockchain address and its actual owner. One investor may use several wallets, while a single exchange address may contain the funds of thousands of clients.

A large balance at a particular address therefore does not automatically mean that all the cryptocurrency belongs to a single investor or that they are about to sell it.

Why do large trades affect the price?

The impact of a large purchase or sale depends above all on the size of the order and the liquidity of the market.

If an investor sells a large amount of cryptocurrency and there are not enough buyers on the market, their order may gradually exhaust the available buy orders. The result is a fall in the price. With a large purchase, the mechanism works the other way round.

In markets with lower liquidity, even relatively smaller trades can cause significant price swings.

Large investors therefore often split their orders into smaller parts to limit their impact on the price. A significant market movement in itself therefore need not mean that someone is trying to manipulate the price deliberately.

When does it become market manipulation?

Manipulation occurs when market participants try to create a false picture of supply, demand or trading activity through deceptive conduct.

The best-known manipulative practices include:

Spoofing – a trader places large buy or sell orders that they do not actually intend to execute. The aim is to create the impression of strong demand or supply and influence the decisions of other investors.

Wash trading – creating artificial trading volume through coordinated trades, for example between accounts controlled by the same entity. This can make a token appear more popular than it really is.

Pump and dump – an organised inflation of a cryptocurrency’s price through promotion, coordinated purchases or misleading information. The organisers then sell their tokens at a higher price, while later investors may suffer significant losses.

These practices are not merely theoretical. In 2025, for example, US authorities dealt with the cases of CLS Global and Gotbit, which were linked to the artificial creation of trading volumes.

However, the cancellation of an order, high trading volume or a rapid price rise alone does not prove manipulation. What is decisive are the circumstances and evidence of the actual conduct of market participants.

What does the blockchain tell us?

The blockchain makes it possible to publicly follow cryptocurrency transfers between individual addresses. However, we cannot always determine who owns the funds or why they are being moved.

If, for example, a large amount of bitcoin arrives at an exchange, it may be preparation for a sale, but it may also be an internal transfer of funds or another operational transaction.

Likewise, a large outflow of cryptocurrency from an exchange does not automatically mean that investors are buying and plan to hold for the long term.

It is therefore important to distinguish between a trade that has actually been executed and a mere transfer on the blockchain.

Can whales predict market developments?

The behaviour of large investors is the subject of numerous analyses. Some research suggests that large holders may, in certain periods, increase their positions ahead of price rises.

For example, a study focusing on Ethereum between 2018 and 2023 found a relationship between the activity of large holders and subsequent price developments. The authors pointed out, however, that the results constitute neither proof of manipulation nor a reliable guide to predicting future developments.

Following whales can thus provide interesting information about the market, but on its own it is not enough for successful investment decisions.

How can suspicious activity be recognised?

When assessing reports about large investors, it is important to focus on where the information comes from and what it actually means.

An unusual transfer need not mean a sale, and a sharp price movement need not be the result of manipulation. Price developments can also be influenced by automatic trading orders, changes in liquidity or the forced closing of leveraged trading positions.

Warning signs may above all include coordinated calls to buy, promises of quick profits or pressure to make an immediate investment decision.

Investors should therefore verify the available information and not treat every significant move by large holders as a signal to buy or sell.

Conclusion

Large investors hold a significant position in the cryptocurrency market, and their trades can influence short-term price developments. That, however, does not automatically mean they are manipulating the market.

Manipulative practices such as spoofing, wash trading or pump and dump really do exist. Proving them, however, requires concrete evidence, not merely unusual transactions or sharp price swings.

To properly understand the cryptocurrency market, it is therefore essential to distinguish between actual trading, movements of funds and deliberate manipulation.

Not every whale activity heralds a change in price, and not every significant price movement has a hidden organiser.
