Hey there.
I really do not know. Its not a real site in the sense its hosted on a free host site. These things are never worth much.
But you said you have made 2600 in such a short time.. maybe someone will see value in it…
Personally if i made 2600 from it i would continue since your going to making way more money then you could selling it.
Kind of like why sell if its a cash cow?
Good Luck
