Bitcoin silver... Another FORK

Hey! How are you all?

I have been reading about bitcoin and got the news that another bitcoin fork is going to happen. Guys, I mean what is going on? How many bitcoin forks is gonna happen, and  I don't understand this, they say only 21 million bitcoins are supposed to be made. and they keep on making new ones out of it. What is the point here?

If you could say anything about this then, please share your knowledge. The price is going high and what is your prediction of the price after the fork? Is Bitcoin Silver is necessary?
