Ripple is a good choice. I think it's worth investing in it - just Ripple is a great long term investment. 
Riplle is one of my favorite coins, I think Riplle has great interest so it has good potential for a long time. Buying Riplle now is the right time because now the price is in the low category. but in these conditions do not panic easily when prices go down because the market is still in an unstable condition so stay patient and trust Riplle even though the price continues to fall.
