Why your title so freaking misleading. Ok that's not the point. But i agree with you. 2020 will be great year for altcoins.
2018 is the year of Altcoin but the worst one, not the good one. Thousands of investors lost their money in this year and they will remember this year till the end of their lives. Some people bought bitcoin for more than $18000 and in the start of this year the price collapsed and they lost almost $13000 in one bitcoin and also lost big money in Altcoin. Ethereum price also dropped about $500 which is also a big amount for small investors.
