Most crypto estate planning mistakes have nothing to do with tax and everything to do with access. A family can hold a valid will, a grant of probate and a folder of statements, and still be unable to move a single coin, because what moves crypto is a secret rather than a signature on a form. The five below come up again and again, and each one has a fix that costs an afternoon.
Mistake one: writing the words into the will itself
This is the error that feels most responsible and does the most damage. A will that goes through probate becomes a court record open to anyone who asks for it, which is why estate lawyers who handle digital assets warn against putting keys or recovery words inside the document and recommend that the will point at instructions held somewhere else instead.
The timing makes it worse. Probate is slow, the file is public long before your family has worked out what they own, and people do sit and read those records looking for exactly this. Reference the existence of the holdings in the will, name who should receive them, and keep the material that grants access outside the filing entirely.
Mistake two: assuming an exchange will hand it over on request
Coins sitting on a trading platform look like the easy case and often turn out to be the slow one. Several large platforms have no beneficiary designation at all, so there is no equivalent of the form you filled in at your bank, and your executor is left submitting a death certificate and probate paperwork to a support queue and waiting.
There is also the question of whether the platform can deliver. QuadrigaCX collapsed in 2019 after its founder died with sole access to the company's cold wallet keys, and ABC News reported about 190 million dollars belonging to some 76,000 customers stranded behind a password nobody else had. The Ontario Securities Commission later concluded the business had been run as a Ponzi scheme, which complicates the story without changing its lesson: a balance on somebody else's platform is a claim against that platform, and claims behave differently from coins you hold yourself.
Mistake three: telling nobody the wallet exists
Coins nobody knows about are indistinguishable from coins nobody owns. Chainalysis, working from the assumption that anything untouched for five years or more is probably gone, put the volume of lost bitcoin at roughly 3.7 million coins, and a large share of that is not theft but ordinary forgetting: people who moved house, people who died, people whose families never knew where to look.
Your heirs need an inventory even if they never need the keys. A short list naming which assets exist, roughly how much is there, which device holds them and who to call for help turns an impossible search into a task somebody can finish. Keep that list current and keep it apart from anything that grants access.
Mistake four: leaving instructions only you could follow
Write the instructions for the least technical person who might have to use them, then assume they will be reading under stress on the worst week of their year. Terms that seem obvious to you, derivation paths and passphrases and which app pairs with which device, are a foreign language to somebody who has never opened a wallet, and an instruction like "restore from the backup" means nothing to a person who has never restored anything.
Name the device by what it looks like, say where it is, say what the words are for, and say what the first three steps are in order. It also helps to name somebody outside the family who understands this and would be willing to help, because an executor who knows there is a phone number to call behaves very differently from one who is guessing.
Mistake five: never running a dry run
Nobody tests this, and testing is what separates a plan from a hope. Take the written material, go to a different device, and restore the wallet from it while you are alive and calm enough to fix what goes wrong. People discover a missing word, a passphrase they never recorded, a set of words that belongs to a wallet they stopped using two years ago.
Do it once a year and after any change to your setup. Treat an untested plan as unproven, because until somebody has followed it end to end, all you know is that it looked right when you wrote it.
What your backup has to survive when you are not there
Every arrangement above still rests on one question: how many things have to go right for your family to get in. Paper fails to fire, water and time. Steel plates answer the first two and are the sensible upgrade from paper, though the underlying trade-off holds, since one object grants full access to whoever finds it and total loss to everyone if it disappears. That is a difficult thing to design an estate around, because the safer you make it against theft, the harder you make it for the people who are supposed to find it.
TapSafe Recovery was built around that tension rather than beside it. The Recovery Tag carries half of what a recovery needs and your paired phone carries the other half, encrypted in your own iCloud or Google Drive rather than sitting on the handset, so both halves have to come together before anything moves. Optional Recovery Contacts each hold a quarter share, see nothing about your balances or addresses, and are set up in person by tapping their phone, which gives you a way to involve the people who would be sorting this out without handing any of them the keys today. Your seed phrase stays available on the device as a last resort under the BIP-39 standard, so nothing here locks your family into one manufacturer.
Where to start this week
Write the inventory first, because it is the piece your family cannot reconstruct and the only one that helps even if everything else is half done. Move any access material out of the will and into a place your executor can be told about. Then restore a wallet from your own written instructions and see whether they hold.
Ryder One is 149 USD for the Starter Combo, and the Super Safe Combo is 179 USD. Keys are generated inside an EAL6+ certified Infineon SLC38 secure element and never leave the chip, setup runs to about sixty seconds, and the firmware has been audited by Halborn with the report published in full.
