How would you store >100 Bitcoins?

[lyth0s]

Not that I have that many (I wish!), but how would you store >100 Bitcoins? The easy answer is just to say "create 1 offline/cold wallet and put them all in". But what about risk management? IE how do you store a very large value of coins while managing risk against hackers, forgetting passwords, the obvious need for at least 1 hot wallet, portability, easy of use, house fires, EMP bomb's (lol), or if a foreigner had to flee a country while taking no assets etc etc.

I'm looking for real responses and ideas. Please keep the trolling to a minimum

every 5 or 10BTC ... use a new wallet.
i do this.

when you pay ... seller don't know if you have more than 5 or 10 BTC.

I should do this.

New wallet or new private key? What about a reasonable cold/hot wallet mixture? And what about online wallets so that your coins are portable?

I feel there should be a good ratio of such wallet types, I just don't know which ratio would be best.

It seems like 1-2 cold storage wallets, 1 PC hot wallet, 1 brain wallet?, 1 phone hot wallet and 1 internet hot wallet might work, but then what ratio of coins to each wallet?

I would just do 10 paper wallets with 10 Bitcoins in each - there is no real need to diversify wallet types, just diversify the coins

With 10 paper wallets you risk them being destroyed. You also have the problem of not having a true hot wallet in order to send bitcoins on the fly with unless you carry the paper wallet in addition to your phone and scan in the key.

1 wallet. I'm a lazy guy..

[1Referee]

I would store 5x 20BTC or just 2x 50BTC. There is nothing wrong with keeping everything in one wallet. I prefer to spread it.

Offline, and on atleast 5 different usb sticks. 

[justusranvier]

Armory.

i use 1 android bitcoin wallet (with 200mBTC).

i use "many" cold wallet (separate) from bitcoin core.

wallets are stored in 2 hard drive and 5 USB key with many folder by date (10 folders with the same "many" wallets increase by 1 every new wallet created).

You can corrupt 1 file ... but you can't corrupt 100 files separate by time and folders.

~80% in 1 brain wallet, ~10-20 btc in Coinbase/Armory or similar trusted 3rd party.

I also read someone keeps a ton of paper wallets, each with 1 or 2 BTC, I liked that too but only if you have a TRULY safe and secure place to store them.

Remember, the safest protection for your wealth is nobody knowing about it.

I think splitting them up is a good idea. I split my coins in increments of 10, I have been thinking about lowering to 5, that way if I need to sell some without compromising my other coins, i just redeem the 5 coin, or better yet, have  a mixture. 1 25btc, 3 10btc, and the rest 5btc..

Quantity won't help. 1 good cold storage wallet should do fine.
They will be safe. I never split up my coins unless I have to.

[4onesea]

I would make ten cold wallets using a live cd and storing the dat files on several different usb drives.

[Malin Keshar]

splitting among wallets.
paper wallets. You can write the keys in random pages of random books you have, or any other place that looks like a nice place to store valious stuff.
put your keys in a "broken" phone hidden in some image, that you only will bring with you if you need a quick exit or all others keys are destroyed or unacessible. I would recomend devices without internet, like old mp3 players that looks old enough to be broken
print the binary of the text file that stores your key. Anyone that gets that will have a hard time figuring out dafuq is that lots of 0 and 1.

how do you store a very large value of coins while managing risk against hackers,

Keep the wallets on a computer that is never connected to the internet.

forgetting passwords,

Use N of M passwords. For example, 2 of 5, with the 5 stored in different places.

the obvious need for at least 1 hot wallet, portability, easy of use,

Armory. It will do both hot and cold wallets, and let you monitor and send money to the cold ones from the hot one, and do N of M.

house fires, EMP bomb's (lol), or if a foreigner had to flee a country while taking no assets etc etc.

N of M passwords. Some copies on paper, some in the cloud, etc. If you care. Personally I am fairly happy with backups (a) on my PC; (b) on my person; (c) on Dropbox. All encrypted. It's unlikely all 3 will get wiped simultaneously.

I keep a significant portion of my bitcoins on an encrypted ironkey usb drive stored in a security deposit box and stored in a zip lock bag (in case of vault flooding, which was an issue in Manhattan after hurricane Sandy, although the ironkeys are very well contructed and would probably work after a year or more underwater). The ironkey uses hardware-based encryption and automatically erases and disables the drive after 10 wrong password attempts, so brute force isn't an option. The file on the drive is itself is encrypted with a password in combination with a keyfile that I don't keep anywhere near the bank.  I have an encrypted copy stored within a personal ironkey, also using keyfiles that I do not keep locally or anywhere that the drive itself routinely travels to or gets used.

Just remember, you're much more likely to lose coins than have them stolen (i.e., forgotten password, hard drive failure, house fire, ruined paper wallet).  For that reason I always make sure I have 2 working copies which are physically separated.  I also have redundancies for the keyfiles, which are necessary to recover the wallets, but its easy to keep copies of those in various places since they by themselves are not valuable to anyone.  The keyfiles are not labeled as such, obviously (you can use any kind of file).

Keep your secret in paper inside some cheap electronic.

For example, your fix phone, or some old computer.

Or inside free holes in objects that can't be esily stolen, like your bed or Cupboards, but of course the place you will pick must be hard to others guess.

Armory does not belong in the same category as Coinbase.

Coinbase is a Bitcoin bank that takes your actual coins and gives you bitcoin IOUs for them.

Armory is the best cold storage solution for holding your own coins, better than brainwallets or paper wallets by far.

You do not really gain any diversification by not splitting up coins
