Which will be the best Cryptocurrency in the first 3 months of 2019
i'm sure ethereum will be the first growing cryptocurrencies in the first 3 months of 2019 my friend
then, Cardano and Waves will follow ethereum
based on what i see eth is still dumped at a verry low price in which i dont think that it can grow faster when compared to other coins that you stated above . but lets not foget the fact that those altcoins will still be dependent on the flow of bitcoin . therfor , bitcoin should be the one that we must prioritize because this is the only way to help out other coins to recover .
