ETH is highly correlate with BTC trend, and now Btc is not doing quite well
I disagree. ETH is not much affected by BTC price but it sure does puts much impact on other alts.
Once BTC starts rising, all the cryptos will eventually rise in price too.
2020 is the year that can bring an upward trend in prices as BTC halving and ETH 2.0 Update are going to be a big factor.
Someone posted a chart a few days ago that shows the price history of Bitcoin over the years. Well, it turns out, the bull market comes right after the halving every single time. There's always been a slight bump in price before the halving, then shortly after the halving occurs, the price skyrockets. Between that, and Eth 2.0 like you stated, next year should be huge for crypto. Try to stock up while you can.
