20% cash (either USD or EUR, preferably USD) 20% short-term high-grade bonds 20% stable equities 20% gold 20% real estate/bitcoin/whatever you want
that'll do you well for the next few years. once central banks stop tightening credit and go back to printing money, then wind down your cash/gold for equities/bonds. we're close to another 2008 moment as the Fed, ECB, and JCB (three largest sources of global credit which the economy exists on) are tightening policy/rising rates from literally 0% over the past decade. Its gonna be rough. Cash is king during market corrections, not gold or bonds or anything else, but cash. Gold will hold value through the correction then explode when central banks inevitably have to monetize tens of trillions more in debt as they did in 08. Cash is best right now. At current trend gold markets will likely explode later 2019, 2020. Right now rising gold price is them pretty much calling central bank's bluff at being able to return to 2%+ rates on credit, from a decade of 0%. anyone with a brain for finance knows that's a joke.
Always use charts to plot your entries/exits, and don't buy all at once, rather slowly accumulate positions over time.
