Typical sick patens with sever dementia can live between 10 - 30 years.

As it is not easy to kill a typical patent (the global economy) when they have lots of nurses (economists) tending to every need, you will need to administer a Poison.

The "Rat Poison" Bitcoin if taken in the correct dose can be fatal to economies with sever dementia. However if a fatal dose is administered, its taste will be detected and the poison dealt with by the nurse's aide (the policy maker).    

For best results administer undetectable amounts Bitcoin, and wait for your inheritance.  Given the patent history, I'll give a total system collapse about 10 years provided a seedy dose of Bitcoin is ingested.  

Should all the nurses agree to take an early holiday and stop caring for the terminal patent, I'd agree with your 2 year prediction, otherwise just hang in there.  

It was rather meant as a joke. But ok why not. I offer you 0.1 BTC If the system does not collapse within two years. If it does you pay me 0.1 BTC. But how do we "measure" whether the system has collapsed or not? Majority vote from the forum users comes to my mind.

By collapse I mean the system has gone out of control by the FED. This would manifest either in Hyperinflation followed by a currency crisis where the dollar looses virtually all its value or a hyperdeflation where you see massive bankruptcies and the meltdown of our retirement savings (because it is lost). The only thing that would be going up are precious metals and ... of course Bitcoins  

We're still a ways from that. Japan will blow up before the US does, and most likely Europe.  Like it or not the USD is the prettiest horse in the glue factory or the least syphilitic hooker in the whorehouse for now, take your pick of analogies.

When the system collapses in two years (lol)  bitcoins will becomes worthless as there will still be nothing to buy with them. In the meantime buy some postage!

The banks are the ones benefiting, those too large to fail banks, while for the rest of us, we can only watch and wait for the ultimate collapse.

i would add to it investing in own water, power and food plants, it will always be handy

The market moving up and down is not always an indicator of economic health. The reasons for the move are what matters.

It seems backwards but it makes sense. Gold and commodities are not great right now, interest rates are almost 0. So stocks are seen as one of few places to put your money in order to get a meaningful return.

Once cheap money disappears and rates go up, then money will flow out of the stock market into other things. The market would then likely go down and the dollar go up.

When or if that happens no one knows for sure.

Only as long your pension fund is not wiped out. What do you think your pension fund manager does with the money? He invests it in assets like stocks and bonds. In a deflationary collapse those assets go down and if governments become insolvent bonds loose even their entire value. That is why your retirement saving isn't save even in a deflationary environment. It's called counter-party risk.
