You could invest on Ripple , I bet Ripple will rise a lot in the near future , the price of Ripple now is just 0.79$ in Coinmartketcap.com, you can invest into Ripple for long term. Some of other coins you can research such as : DASH, MONERO or litecoin, those are some coins of top 10 but have good growth in coinmarketcap.com , then I think its very potential for investment.
