We are in speculative markets. Probably everything we see today is eventually doomed. That doesn't stop people from speculating.
I assume with that you are referring as well to the current stock market, housing prices in big cities, the value of the dollar, etc?
To be honest I wonder where the common man can currently safely store the proceeds of his work just keeping it's value?
That is a difficult one to answer. If you leave your money in the bank/savings account, you get zero return.
If you invest in stocks (buy the ATH!) then you could get some profit, but it has to be due a big fall.
Bonds pay very little for what I believe is a bigger than advertised risk.
So Bitcoin, the price is historically high at the moment, but could easily rise 100%, or fall 75% in the next year. That is worth a punt and should be part of your portfolio, but is dangerous.
I would say that the 'safe' bet is PMs. I would have said oil, but it really seems like the $100+ prices are gone now due to fracking, and global demand will fall in the future with lots of countries desperate to pump everything they have, as soon as possible, before it becomes worthless!
