hi @msa117
I, too, like you do not understand all these declines and I would also like to answer people who understand a bit more than me but this whole thing is a game of money always the value goes up and down I pay attention every week stocks that the value rises and falls and there is not so much to do so that if You invest money can also lose it or part of it then in my opinion if you invest already do not invest all of these keep a bit on the side for a rainy day I'm not a gambler wife but there are those who do and have a good luck
