I just started the investing game so i'm a bit late and I bought last week when it was at its highest so I did take an L, but the maker of those above videos really did sell me on their points. Despite whatever noise on market manipulation the market always wins and the factors behind a silver rise are so strong in the general supply and demand area and macroeconomic factors.
Since I posted the video, I must say that the pumpers videos must be taken with a pinch of salt. So far, I've not seen any channel that managed to accurately predict the bottom out of gold in Oct-Nov last year and silver in Feb-May. Most are just bullish all the way.
