Because you read the whitepaper you realized that it is a good competitor with ethereum? You are a clown.
I will never get tired of see this kind of feedback from all the newbies that are around here posting crap with no reason.
Cardano is a serious coin, they have a very strong team and great potential. I read their white paper and realized that this is indeed a good competitor to ETH and NEO.
Cardano is a good coin, but ethereum will always be better in every aspect, and it has been on the market for a long time, everybody is going to prefer buying eth instead of ada.
Stellar is a solid project too, but it needs more marketing to be a bigger one.
