My history with thisBought 28K worth back in 2013ish. sold 2/3 in 2020 after the panndemic bounceback and reduced to my original stake. Took out about 69K. So even if it goes to 0 So I will leave my 2K shares. When I first bought it it dropped a good 35% but I held and it worked out. May buy more but no hurry. Still holding the bag of 2K shares now. When rates drop they will be more profitable
