is this normal?

see estimated win, is it even over 1? If not, keep on entering and hope for better luck.

i entered over 800 giveaways, before i won my first one.

Normal? Yes.

Should you keep entering? Maybe not, the time invested vs reward may not be suited to you.

Some people enter thousands without winning.

just keep trying, you are bound to win sooner or later.

of course you can improve your chances by giving a game away yourself. but i can totally understand, if you don't want to do this before you won something.

yes yes
