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.
I don't think bullish has happened yet and there is no fundamental reason that could trigger bullish to come. But I agree with you that Bitcoin halving and Ethereum 2.0 later is a fundamental reason that will bring bullish and I am sure it will have a good effect for many alts or often called the altcoin season.
