I have been trading on Bitrue for awhile now, I enjoy Bitrue because there fees for trading a very low and if you purchase just a little of their BTR coin you can set it to use the BTR for fees instead of the currency your trading. This is a plus in my book.

     A few months ago I happened upon the XDC/XRP pair on Bitrue and began noticing that everytime XRP rose or dropped in value XDC would do the exact opposite, so I began trading the pair when I felt the market was changing on XRP price, I traded all my XRP for XDC when the price of XRP begun dropping and held it untill I felt it hit support, I then traded back for XRP, And like I thought XDC's price went up in correlation with XRP's price going down so I ended up with more XRP then I started with.

  As the price of XRP started rising significantly toward the end of last year, I watched XDC tank in price, I knew XRP couldn't go to the moon without slight Pullbacks so when the price reached around $.67 ea. I traded for XDC, I lucked out because XRP ended up dropping back to around $.47 and XDC Price went up significantly during that time, so basically I kept the same amount of "dollars" instead of losing dollars if I just held XRP, only difference was I had almost twice the amount of XRP when I was done!!!

  So I have kept doing this since and have accumulated around 8x the amount of XRP that I had originally. If your interested in doubling your investment during fluctuation then I would recommend trying this out. Good luck!!
