What Happen when Binance will list a new cryoto currency

 What Happen when Binance will list a new cryoto currency?? 

I am new in trade. But I always analysis market with coin price from Binance or others

>>

We know Binance always list new coin day by day. New coin means a new tread. There are many website for trading.  And all of the coin is not available to all web site or market. So day by day, much of the site will list new coin.  When a site list a new coin, then there will be happened a great trade. 

So, What Will happened? 

There happen two things. 

1. The price of this new coin is going high in a moment.

2. The price of the new coin is dropped in low price in a moment.

I Don't know why this happen. But My small knowledge things two things.

 (a) Supposed,  Binance will list a new coin. Most of the user of Binance will starting bought this coin by interest.  So this, within a few moments,  the price of this coin is going to sky.

(a) Second things that will happen,  when binance will list new coin, they will make scam. I Don't know why this happen! When people starting bought new coin, suddenly the coin is dropped in low price. That's means market crash. 

So, We have to take tread with a new coin, very carefully.  It’s so risky.  I think without information, or without signal, we Don't need to take trade.  

Thank you...
