I am making research about NEO and think that it is also quite stable. Because, NEO indeed is an upgraded version of ETH and more and more projects are being based on its platform. Athough it is new, many investors looked at it with a positive view.
If I think personally there does not seem to be any stable coins,
because every time the coin always moves for sure,
so even though it's neo or ethereum it seems like it's not a stable coin
