, because mainstream and a lot of people make bitcoin only ' cryptocurrency ' . so the main attention will be in bitcoin Cardano, ADA is going to be a huge coin in 2018. I can see it over taking ETH. But never BTC.
I don't see that being the case, Cardano is a newcomer to the scene whereas ETH has been around a while. I think 2018 can be the year that ETH can pull itself close to bitcoin in terms of market cap and challenge for no 1 spot. I agree ADA will do well but not as well as you are predicting.
