altcoin goes green if you see market conditions return to green, but now the market conditions have not stabilized so I think this affects the current price increases and market conditions.
A major factor or event is affecting altcoins turning to green and turning it to red again these days and one reason of that is the fact that bitcoin is down again for a couple of times this year. Let's not trust right away what we see because as cryptocurrencies are volatile, a sudden change of cryptomarket cap and color is inevitable.
Today the market is bleeding, again its because of the ETH news which people believe not a positive news about bitcoin.
I don't know if this will continue to dump, but if I am right, we are here before the ETF speculation and it's the lowest, so I don't expect it will dump more.
