I firmly believe, when the crisis / recession or market crash will come in 2018, investors will turn into Gold. And Golds price will storm all time highs!
Also Bitcoin will be "safe" investment too. Just for now, still gold has more capital invested than BTC. For a simple reason: Gold has been around for much much longer, and some people don't understand the concept of Bitcoin. "How intangible asset can be valued so high".
