ADA is worth 1/10th of ETH in terms of market cap, but has so much more potential. Completely lost my confidence in ETH as new ICO's on decline, unknown inflation etc etc.
I think that is the right choice if you think selling all ETH and Bought ADA will give you greater benefits. But, don't forget to keep an eye on market developments and do an analysis to develop a better strategy because according to some people ETH is a big potential coin.
