Ripple's value has been going down ever since it's meteoric rise. In the future it will be up from here, but in the shorter term I am not confident we have reached the bottom yet. The BTC/XRP chart gives a different outlook than the USDT/XRP chart.
All in all, investing in Ripple doesn't seem as attractive as investing in other coins.
Interesting. Thanks for the comment - my feeling was that it had hit the bottom but I also wasn't looking at BTC/XRP chart either - will do so now. Cheers
