Every time I invite someone to join I don’t get my 100 coins. I have lost 800 coins so far

I did lost them every time I invited someone I don’t get it if you backtrack all the people I invite you will see that I didn’t get them. I invited two people today and they got there coins I didn’t get mine

you haven't lost anything because you never had them to start with
800? so you didn't get anything the 1st, 2nd, and 3rd, time and keep going?
