Building a Liquidity Buffer Before You Need It
Being a forced seller is how an ordinary drawdown becomes a permanent loss. The defence is entirely outside the asset.
The most consequential decision about holding a volatile asset is made in the rest of your finances, before you buy any of it.
The mechanism
A decline is temporary if you can wait. It is permanent if you have to sell during it.
Whether you have to sell is determined by whether you have money available elsewhere when something unexpected happens. Cars fail. Jobs end. Roofs leak. None of these consult the market.
Someone with no buffer, holding a volatile asset, is short an option they did not know they had written: the obligation to liquidate at whatever price prevails when life intervenes.
What the buffer needs to be
Held outside the volatile asset. Cash or near-cash, in the currency you actually spend.
Sized to your actual circumstances. The conventional advice is several months of expenses. The right number depends on job security, dependants, and what would happen if income stopped.
Genuinely accessible. Not locked, not subject to an exit queue, not requiring a device in a drawer.
Untouched by the position sizing calculation. The buffer is not part of what you are allocating. It exists before the allocation question is asked.
The mistake I watched
A friend held a meaningful position, no buffer, and encountered an unexpected expense during a decline.
He sold at the worst available price, for reasons entirely unrelated to his view on the asset. The position later recovered and he was not in it.
The loss was permanent and was caused by the absence of three months of expenses in a savings account, which had nothing to do with crypto at all.
The staking version of the same trap
Assets locked in staking have an unbonding period, frequently weeks. During that window you earn nothing and cannot sell.
An emergency arriving during an exit queue produces the same forced-sale dynamic with an additional delay attached. Anyone staking a meaningful share of their holdings should treat that portion as illiquid for planning purposes, because it is.
The three tiers, from the bottom up
Buffer. Cash, outside everything, sized to your circumstances. Comes first.
Working balance. At a venue, for rebalancing and purchases. Small enough that losing it entirely would be an annoyance. Mine sits at the exchange I have used since 2021.
Long-term holdings. Self-custodied, sized so that a seventy percent decline cannot force a sale because the buffer covers what life requires.
The ordering matters. Most people build these in reverse, which is why forced selling is the most common way an ordinary drawdown turns into a real loss.
The test
If your income stopped tomorrow, how many months could you continue without selling anything volatile?
If the answer is less than three, the position is too large regardless of how confident you are about the asset, because the decision about when to sell has been delegated to circumstances rather than to you.
This is a personal account of holding through market cycles. It describes what one person did and why. It is not a recommendation, and past cycles do not predict future ones.
