Well, biggest hedge fund manager ex. Ray Dalio says keep 5-10% of gold in your portfolios, shares outlook for 2019 - and more at current - :-))
Eric Sprott keep all in gold mines and precious metals - like Kirkland Lake with high grade and low cost mines - I think B2 Gold is around the corner for breakout -
past week Gran Colombia made new yearly high but used to trade for >800/sh and has a long way back UP to FLY ^ as a very high grade Segovia Mines and low cost production - its like the fund managers move as a team to make it high :-)) God Bless
