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 Ethereum is better than ADA, because ethereum is very popular and many people invest in Ethereum. So i prefer in ethereum, i think ethereum will grow 2-4x in 2020. So be petient for it, if you want to make more profit.
