How would you store >100 Bitcoins?

[QuestionAuthority]

I like the fake water pipe idea. What ever happened to the old stand by the Cookie Jar? Growing up my dad used to call the cookie jar the college fund because he would hide money there in a baggie. My mother had a weird sense of humor. She took dad's money once and told him she thought I might have a drug problem.

I'd prefer to sell them, I would be too worried to lose them all making some mistakes using cold storage wallets.

Although not trying to solicit any sort of business (just trying to gauge how people are thinking) do you think if someone were to offer you a service to "help you to do cold storage" with M of N addresses (i.e. that needed say 2 of 3 sigs) would that change your mind?

I've always preferred the word Cookie over Biscuit. People trust Banks too much these days. My Grandma passed on her distrust of banks to me and her love of gold (you soon realise what money is when you hold a one ounce gold coin - beautiful).

That's true, I have quite a few Canadian Maple Leaf one ounce coins and they are cool to just hold and look at. When you get into big dollar amounts it can be unwieldy though. That's one of Bitcoins strengths. You can have millions of dollars taped to the back of your ID in your wallet and no one will know it.

I diversified into Bitcoin after being a Goldbug for years (I resent the modern tags such as stackers, preppers etc..). Sadly being a Goldbug I was sceptical about Bitcoin at first and missed the main party (wasn't sure whether it would hold purchasing power over time - whoops). Despite holding more Gold than Bitcoin I would still prefer Bitcoin to Truimph however the elites hold Gold and therefore it will inevitably play the greater role in the future monetary system.

If I were a millionaire, I'd put it all into bitcoin, and use Coinbase's vault, with an extremely tough password and all levels of verification.

why not cold storage?

[romerun]

Mtgox. That's what I did.

[tupelo]

Ha, the only correct answer!

[V8x8d]

Mtgox. That's what I did.

What percentage of your BTC were sitting in MTGox? I always thought the great advantage of BTC was that you could have physical possession of it (were you speculating?).

[Ayers]

The safest place would be multiple paper wallets, and make sure you make AT LEAST 3 copies of each. Store them in places around your house you will remember.

No one can touch them that way.

Wouldn't someone be able to steal your coins if they robbed your house? Or if they simply found one while being a house guest of yours?

If has knowledge about BTC, it will happen but the chances are less. Anyway, there are many safe places in home like refrigerator.

~~MZ~~

under the tile is much better, with some deep digging, you could store your paper wallet there

[rocky45]

Securing a cold wallet with a strong passphrase which you'll keep in a safe place of course will do it.No need to make many wallets.

All. Back in the day when bitcoinqt was way worse than now. I pulled them off to the classic client when they had the gangbang with coinlab.

For no reasons, I trusted Gox more than blockchain.info

I had no 2fa or anything special set, I even recommended a guy to store his coins on Gox.

Sall good.

This is a sincere answer: Given the variety of answers in this very thread, rather than universal endorsement of a single wiki page listing best practice, I'd look to:

Outsource security to full time security professionals;
Who store and manage money at their site;
Who are insured against theft so that even if they get rolled, I won't loss my money;
Who have a good IT systems in place to keep my account;
Who could release funds to my family if I died.

In other words I'd convert the Bitcoins to cash and keep it in a bank.
But, of course, I know that's not the spirit of the question. You are just asking for the best practice for the highest security when storing bitcoins.
Apart from joining you, OP, in surveying the other answer I'd only add: You could look to coinbase. They do have more than 100 Bitcoins in their possession; and of others peoples money furthermore. The chief thing to note is that they store most of their funds offline in "drives and paper backups [that] are distributed geographically in safe deposit boxes and vaults around the world". https://coinbase.com/security

a multisig where one key is trezor, another is on a secure, identity-verified web service, and the third is with the wallet provider
for my cold savings the trezor and its seed would go into a safety deposit box
my spending/income coins would also be handled by another trezor that stays at home in my home safety deposit, from which i transfer into my smartphone hot wallets on regular intervals. the seed for my home trezor would also go to the bank. income designated for savings would be shipped off to my ultra cold trezor also at regular intervals

Funny you should pick that number, personally for each 100 I've created two laminated paper wallets, plus an encrypted SD card, and put them in three separate safety deposit boxes that only my wife and I have access to. There are no copies at my home or anywhere else. Of course the wallets were made with a computer that has never been and never will be online in any way.

I have never tested any of my offline addresses, so I am trusting that Armory didn't make a mistake, and neither did I. IMHO once you send anything from an address it is no longer a secure offline addy, even if you do an offline transaction with software like Armory.

[logger]

The only way I could really lose my BTC and other assets (I also hold some LTC and a crapload of NCM in my boxes) would be the government or bank somehow seizing my boxes and stealing my Bitcoins, which is unlikely because I pay my taxes like clockwork and operate a legitimate business.

Basically I am trusting the banks not to steal my coins, which when I think about it, is not the hottest idea. For a hardcore paranoid wanting even more security, you could use your own hidden, obviously fireproof, safe(s) at home or elsewhere. Although then you are open to a home invasion type robbery, which I think is more of a risk in this day in age than the banks shutting down and taking the security boxes.

[proofofarat]

Armory with an m-of-n backup with dedicated separate cold wallet and hot wallet computers. Distribute the m-of-n backups geographically and among a couple different safe deposit boxes. In your will write clear instructions on how to recover the coins with the backups. This is the safest way to store coins imo.

[Drendas]

I would convert the Bitcoin to dollars then deposit them in my FDIC insured account.
