Take A Gander... If you will open this link https://finance.yahoo.com/quote/CBTC and this one at the same time https://finance.yahoo.com/quote/BTC-USD/history/ Move the line on the Xtra Bitcoin to see the dates when it dips and when it rises.. Then compare that date to the Bitcoin Price History.. What more proof do you need? As Bitcoin goes higher so does Xtra Bitcoin shares. When it dips, so do they. IMO It would be foolish for us to sell all our shares at this point in time.. Bitcoin may increase to $250,000 or more.
