In general, 2018 is a bad time for making such calculations. However, XRP showed good result. I have noticed that Ripple is not very subjected to the behavior of bitcoin. It can grow while other cryptocurrencies fall, but unfortunately, it can act controversy during the bullish market. Anyway, in November I got pretty good returns when XRP pumped and sold it for bitcoin on CEX. Maybe it's not the wisest choice, but bitcoin is number one for me, and I believe in its potential in the future. Apart from successful stories, it is a good time for investment due to the extremely low price which we may never see again.
