The real question is why does the stock market crash like this? Bitcoin is hyper-liquid and has no barrier to quick sales. It is a small, and has relatively shallow depth and is unregulated. The stock market of the 19th.century was similar and went through comparable boom and bust cycles. I think bitcoin is responding logically to the present market forces.

Risk / benefit trade-off.  Just as you might have $10k in your bank account and $100 in your wallet, I would keep the bulk of my bitwealth in a wallet stored offline and some spending money at an exchange like MtGox. That way you can spend from your smartphone without exposing yourself to much risk.
How much is a tricky question, but I try to keep less available online than the value of the phone. 

It's always a good time to panic.

By all means sell me your coins. This guy says it will crash... So, this may be your last chance before bitcoin falls to negative values.

They are coming for my bitcoins!

How many do I have? 

Oh right, no one knows. 

welcome new peers! 

I don't see where to submit a bitcoin address? How do you get paid?

I know some female bitcoiners, but they would not come here. It's not bitcoin, it's us. 

I don't know? But maybe it is a display of ATMs at a trade show or something?

I wonder what will happen when they figure out that while you may choose to use bitcoin with paypal, almost all the services they offer are made obsolete by bitcoin.

I mean the financial services industry more broadly. I think they simply do not understand bitcoin... yet.

This from the "experts" who said bitcoin would never reach parity with the dollar. 

Your going to bit-heaven for this project. 

Me also. I hope they do embrace bitcoin. I will use the money in my account to buy bitcoin then close it. 

It depends on what they are going after. If it's money laundering and tax evasion then more power to them.

If it is like here I recommend that you learn how to make gunpowder. lol
Last night at the range I could only buy ammo to use there. No ammo could leave the store. Reloading supplies were almost non-existent.

Frontline on PBS is truly one of the best at investigative journalism shows ever. Last night they aired an episode titled "The retirement gamble". It was about what a bad deal the 401k system is. Very eye opening. If you thought you were retiring before 80, then I hope you have your money in an index fund and not a 401k. America is about to retire into poverty.
If you like conspiracies then here is a chance to see a real one. You can stream it below.

NEWSFLASH: Bitcoin not interested in PayPal.

All these seem to imply that nothing happened at the Boston marathon. Is that right? All of the tens of thousands of witnesses are in on this? All the thousands of pictures and hours of video from that day are "Hollywood fakes"? This conspiracy must be so big that only a few people were NOT in on it. I don't know what to say, we are in batshit crazy territory.

I'm going to go talk to the grown-ups now.

If only it were that easy. lol
The best evidence for the weakness of TA is it's existence. If the analyst actually knew where the price was going then why would he/she share it with you? Wouldn't it be more logical for them to keep the secret and invest for themselves?
