Logic
we pick free domain so that we dont need to take 3% - 5% for the  domain fee and also hosting fee
if i buy my own domain do you know who will pay for that domain.. its all the investor
we dont buy domain so that we can give all the earning to all investor
thats why we dont have 3% - 5% fee from our site..
you know why other site become scam because they need to pay for hosting and they buy domain
and also referral program thats why there lifespan is not longer than 1 month and if they still pay for next month they will lose everything..
but our site dont have any plan to run your bitcoin (if you have bitcoin)
because we dont invest anything
So that we can give you everything..
