It took 10 seconds for the brainwallet "password1" to be taken

There are safer ways to hold into btc's ,it's clear that some people generated thousands if not millions of wallets and are using bots with bruteforce to break any weak passwords. To have a somehow moderate wallet you might need to enter a semi-impossible to imagine word with letters/number/signs etc... making it hard for you to remember. Paper wallets might be more useful.

Perhaps not using words would be prudent as lists exist which have fancy titles like DICTIONARY etc

Skynet's new 12nm ASIC chip is able to learn at a geometric rate and can crack passwords at 500T/flop/s whilemining / coordinating missile strikes under WIN7/Ubuntu. Also it is self-conscious.

Fancy computers can quite easily hack passwords so beware!

So if my coinbase has an easy pw, when I do a transaction someone may use the public key to track me and try to crack my pw?  

Is that the way it works?

New to this but want to be secure.

No.  They know your e-mail address and they guess your password and transfer the coins.  That's why you should set up the Authy authentication so they can't do that.

Also, you should only keep spending money in there, not $10,000.
