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.
If according to the analysis you sell all ETH and bought ADA will give you profit then do it. But I think ETH is not bad, I think ETH can recover and potentially or have a big chance for your investment. Everyone has their own strategies, so do what you think can provide satisfactory results.
