With the current economy, the fears about the Brexit, Italy, the Sino-American problems and the general pessimism among investors; It looks like Gold is coming back the past months. At the same time, countries like the EU, Japan & China are reducing their investments in the economy,
(it should also reduce demand for the USD?)
Even the Central banks are buying more Gold (+13% from the previous year). Economists predict a dark year for 2019 and it seems a lot of large funds are now buying Gold massively. Especially from Asia and Soviets.
I think people use a lot of money to buy gold to preserve their money. It is not a new trend. When the economy stabilizes, they will definitely invest in crypto and the stock market. Do not worry, everything will be fine.
But most investors are choosing the investment opportunities based on how quickly they could get more returns for their investments. When the economy stabilizes, the returns from normal stocks and shares will be very less then there will be plenty of chances for more investors get into crypto currencies. But, gold will always having stable running still people prefer to invest on it just for the reason of having it as a store of value.
