It's hard to see all top 100 coins be in green at any point,I've been trading for quite some time, and I don't really remember anything like it. So, my point of view right now it could swing either way, but hard. Anyone got any info on it?
When Bitcoin spikes in price people sell their altcoins to buy BTC. This drives the price down. Over the past couple months a lot of the new money coming into Crypto started looking at altcoins and started buying into them, this is why the alts have generally done well lately.
