i have heard about this project few weeks ago, i think it's getting more popular everyday. in crypto sometimes you can never know unless you take the risk.
Never heard of Kava cryptocurrency. But the OP seems to have no knowledge about what stable coins are. Litecoin is not stabe coin. Stable coin is a digital currency that has a fixed value
I have not heard about this coin. However, I tried to search for it and it seems that it gained a lot of value in the past one year period. What's quite fascinating about it is that the recent crash never had any effect on this coin! However, its value depreciated in the 24 hour period as of writing this.
