fastest growing peach tree

I have a peach tree growing out of the ground in the spring, oh boy, it grows so fast that in the first year it reached beyond my height at about 6'.

That's a speed I have never seen in my whole life.

Could anyone give me some explanation? How doI enter the competition at the Guinness world records?

The seed must be from a foreign variety of peach, as I almost always shop for fruit from the Asian markets in the area,and the peaches are ususally of Asian origin.

What do I expect from this tree? Should i let it grow to bear fruit and see what kind of peach it is?

What if it's the best fruit I like? Can I legally sell branches for grafting?
