Both Ripple and Litecoin has been doing greatly in the market of late with litecoin even outperforming other digital currencies at some point.
between the two, which one would you invest in and why?
You should invest in Litecoin.
Bitcoin and Litecoin are similar in many ways, but they are also very different.
There is a fixed amount of Litecoin in the world - the volume of Litecoin never exceeds $ 84 million. Once we reach that point, the Litecoin coin is likely to be broken down into payments over time.
Ripple is a highly speculative asset, not too much value in the long run. The recent price rises were mainly due to FOMO related rumors such as listing on Coinbase, partners will use XRP. So the ripple will be the right currency for the speculation.
