    Summary

    Execution method for a large crypto position How the price is formed Market impact and slippage
    Market order on a public exchange Consumes the order book level by level Highest, and visible to every other participant
    Limit orders split manually over time Fills only at your price, or not at all Lower, but execution is never guaranteed
    Algorithmic execution (TWAP or VWAP) Averaged across a defined window Moderate, spread across the period
    OTC block trade with a request for quote One firm price agreed before execution None on the public market, zero slippage on the agreed price, trade doesn't show on an order book

    A large crypto position moves the market when it is sold into a public order book, because the order consumes the available liquidity level by level until it is filled. Selling without that price impact means executing away from the order book, through an OTC desk that quotes a firm price for the whole block.

    The threshold at which this matters is lower than most holders expect. On a liquid pair, a seven-figure market order can already exhaust the visible market depth, and the difference between the quoted price and the average fill price becomes the real cost of the sale.


    How Much Can I Sell Before the Price Moves?

    The answer is set by market depth, not by the size of the exchange. Market depth measures how much volume sits in the order book within a given distance of the current price, and it is the only number that predicts what your sale will cost you. Any seller looking to minimise slippage starts here, before choosing a venue or an execution strategy.

    An exchange advertising billions in daily volume can still hold a thin order book at any given moment, because volume counts what has already traded while depth counts what is available now. The two are frequently confused, and the confusion is expensive.

    What market depth actually tells you

    • How much can be sold within 1% of the current price, which is the practical capacity of the venue at that instant
    • How quickly the book refills after a large trade, which decides whether a second tranche costs more than the first
    • How thin the book becomes outside main trading hours, when liquidity providers reduce their exposure

    Why the quoted price is not the price you get

    The price on screen is the price of the next unit, not of your whole position. A sell order large enough to walk down several levels of the order book is filled at a worsening average, and that gap between expected and realised price is slippage. On an illiquid pair, it can exceed any fee you were trying to optimise.


    What Happens When a Large Order Hits a Public Order Book

    A large sell order is visible before it is complete, and that visibility is itself a cost. Other participants observe the pressure building, adjust their own bids downward, and the remaining portion of your position is filled into a market that has already reacted to you.

    The chain reaction on a public venue

    • The order consumes resting bids and the price prints lower with each level
    • Each market maker widens its spread as inventory risk rises, and some withdraw quotes entirely
    • Automated strategies detect the sell pressure and position ahead of the remaining flow
    • The lower prints trigger stop orders from unrelated holders, amplifying the market impact
    • Every liquidity provider on the venue reprices, so the second tranche costs more than the first

    Why partial-display orders only postpone the problem

    An iceberg order displays a fraction of the total size and refreshes as each slice fills, which conceals intent without changing economics. The liquidity being consumed is identical and the price impact simply arrives more slowly. A limit order goes further by refusing to trade below your level, but it converts a price problem into an execution problem: the order may never fill.

    A dark pool removes the visibility issue by matching orders without a public book, though depth in crypto dark pools remains thin compared with the equity markets the model came from. For a genuinely large holding, any execution strategy confined to public venues manages the symptom rather than the cause, as the sequence a $100M bitcoin holder goes through illustrates.


    How a Block Trade Is Priced Away From the Order Book

    An OTC desk prices the entire position as a single block, at a price agreed before anything is executed. The trade never touches the public order book, so there is no market impact and no slippage against the agreed price. This is the structural difference between over the counter trading and exchange trading, and the mechanics of OTC trading for large crypto holders are worth understanding before the first call.

    What a request for quote actually produces

    You state the asset, the size and the settlement currency. The desk returns a firm two-way price, valid for a short window, for the full amount. You either accept it or you do not. There is no partial fill and no drift between the price you saw and the price you got.

    Principal desk or agency desk

    Type of OTC desk Who carries the market risk What the seller receives
    Principal desk The desk, which buys the position onto its own book A firm price, executed immediately
    Agency desk The seller, until a counterparty is matched An average price once the order is worked

    A principal desk removes execution uncertainty because it takes the inventory risk. This is where deep liquidity matters: a desk can only quote a firm price on size it is able to absorb and hedge, which is why the quality of its liquidity provider relationships decides the price you are shown. For positions between USD 100 000 and 1 000 000 000, an OTC desk is generally the most efficient route.

    The same mechanism serves an institutional investor and a private holder, since over the counter trading is defined by how the trade is negotiated rather than by who is selling. What changes with an institutional counterparty is the reporting around the trade, not the execution itself.


    When Does Phased Execution Make Sense?

    Phased execution spreads a sale across a defined period to reduce its footprint, and it is the right approach when the position is large relative to the market rather than large in absolute terms. A full liquidation of a nine-figure position commonly runs over 4 to 10 weeks for this reason, whether the seller is a fund or an individual holder.

    Large holdings in a single asset behave differently from the same value spread across several. Bitcoin absorbs size that a mid-cap token cannot, so the same nominal amount may require one block trade in one asset and a six-week programme in another. The constraint is always the depth of the specific market, never the headline figure.

    Time weighted and volume weighted execution

    • Time weighted average price (TWAP) slices the order evenly across a window, regardless of activity
    • Volume weighted average price (VWAP) sizes each slice to match market volume, staying proportionate to real flow
    • Both aim at an average rather than a single price, which suits a seller with no deadline

    The line between phased execution and structuring

    Splitting the market execution of a trade is a liquidity decision and is entirely legitimate. Splitting the fiat transfers that follow, in order to keep each one below a reporting threshold, is structuring, and it is a criminal offence in every jurisdiction that matters. The distinction is not a technicality.

    There is no legal ceiling on the amount you may transfer to a bank. A single transfer of any size is acceptable provided its origin is documented. Nine transfers engineered to sit under a threshold are not, and they produce exactly the automated alerts they were meant to avoid.


    What Happens Between Execution and Money in the Bank

    Execution is the fast part. Settlement typically runs T+1 to T+3, but the fiat still has to be received by a bank that will ask where it came from, and that is where large sales stall rather than at the trading stage.

    What sits between the trade and the account

    • Travel Rule obligations, which apply from CHF or USD 1 000 and require originator and beneficiary information to travel with the transfer
    • The receiving bank's own review of the source of funds and source of wealth behind the proceeds
    • A possible account freeze of 30 to 90 days where the bank cannot resolve a question on the origin of the assets

    Standard OTC desks stop at fiat conversion. As a Swiss financial intermediary supervised by the VQF under AMLA, alt.co picks up where they leave off: we document the origin of the position, carry the compliance responsibility as a regulated counterparty rather than leaving it with the bank, and introduce the file to a private bank that has already seen the evidence. We are neither a bank, since we take no deposits, nor a pure execution desk. Our intake review runs 5 to 15 business days, on transactions from USD 25 000 upwards, settled in CHF, EUR, USD, GBP, AED or ILS. Preparing that file is the subject of de-risking crypto origin wealth for private banks, and it runs in parallel with execution rather than after it. The full route from position to bank account is set out in our guide to converting crypto to fiat.


    Frequently Asked Questions

    What is the best way to sell a large amount of cryptocurrency?

    For most large positions, an OTC block trade priced by request for quote. It removes market impact entirely and gives one firm price for the whole amount. Above a certain size relative to market depth, phased execution over several weeks becomes the better option.

    What makes it difficult to sell crypto assets at scale?

    Two constraints, and they are independent. Market depth limits how much can be sold without moving the price, and banking compliance limits how quickly the proceeds can be received. Most sellers plan for the first and are stopped by the second.

    Does the 1% rule apply when selling a large position?

    No. The 1% rule is a retail risk-sizing habit about how much capital to expose per trade, and it says nothing about execution. What governs a large sale is market depth at that moment and the liquidity your counterparty can absorb.

    Can I split my transfers to stay below reporting thresholds?

    No, and it is the single most damaging move a seller can make. Splitting transfers to sit under a threshold is structuring, a serious criminal offence, and detection systems are built specifically to find it. There is no legal cap on transfer size, only on undocumented origin.

    How long before the money reaches my bank account?

    Settlement itself runs T+1 to T+3. The banking side is the variable: a compliance file prepared in advance is reviewed in 5 to 15 business days, while an undocumented transfer arriving unannounced may be held for 30 to 90 days.


    Planning to exit a large position?

    We price the block, document the origin of the assets as a VQF-supervised Swiss intermediary, and deliver the proceeds to a private bank that has already accepted the file.
