Store it on reputable exchange if it is small amount.

Mtgox was the biggest and oldest bitcoin exchange.
Mtgox was a bitcoin foundation gold member with Mark Karpeles as a board member.
In the end, hundreds of thousands of bitcoin were lost.

Tradefortress was highly trusted, and was a great scam-buster.
In the end, inputs.io was "hacked" and over 4000 bitcoin were lost.

Crypto Swap Exchange

I have some coins in coinbase. I am a complete newbie, Can any one tell me a method to get my bitcoins offline. After i saw what happened to "klee" I dont want to take any risk. I searched on google and found some posts about "cold storage". can any body tell me the method on how to do that

1) install a fresh copy of Linux and disconnect your computer from the internet.
2) Put bitaddress.org offline version into it
3) run it and scroll your mouse around with randomness
4) print it out
In order for your wallet to qualify to be a cold storage, it must be created in a computer that is Linux and didn't connect to the internet before. Do test the wallet by sending small amounts into it and sending it to your coinbase wallet, just to ensure it works. Do enable two factor authentication on coinbase and keep small amounts of Bitcoins in the exchange.

Just download bitcoin core and send BTC to this address. Also don't forget to save wallet.dat.

That's not really a cold storage / offline wallet.

For offline wallets, you need to create the wallet offline and never connect that machine to the internet.

How would you rate the security of a QT wallet installed on a brand new hard drive, I just installed windows on, sent BTC to it than disconnected it from the computer..? Also backed up on multiple USB's and encrypted with 40 char pass.

As long as your computer stays offline for the rest of the time its fine. Should'n't have any holes except you might not be able to remember such a long pass and that this option doesn't allow you to sign transactions offline and bring them online to be broadcast - meaning that if you ever need to spend the cache you need to bring the whole thing online.

Teach yourself how to use Armory and take advantage of the offline wallet feature (cold storage). It might seem like a lot of information at first, but once you get the hang of it, it's relatively simple (and much, much better than losing bitcoins).

I'd suggest using Armory (more secure, but requires storing blockchain and DBs; requires ~46GB of hard drive space on your online computer) or Electrum (no local blockchain needed, so minimal local storage). They each have instructions for setting up an offline wallet.

klee put his password online.. thats how he got screwed..

but anyways. www.bitcoin.org is the main reference point for the proper wallets and information
i prefer the full proper program bitcoin-core. but others prefer light weight clients like multibit, armory, electrum
