The first few days, any coins have good supply and demand & not exist good or bad news.
Increases or decreases OTHER COINS prices depends on what factors?
Why would a new coin has good supply and good demand?
Yeah indeed, that's just nonsense.
It
might have high supply because it was premined. Which is usually a bad sign.
It
might have high demand because it has new and unique features.
Probably no alt coin has high supply and high demand. It just makes no sense, as they would cancel eachother out and result in either low demand or low supply. I just assume "good" here means high.
No alt coin has a high demand or they would be valuable, lol.
