This site freebitco.in offers Satoshi which is very smaller unit if bitcoin everytime you check in to the website. The time limit is there to claim free Satoshis which is not even equal to a paisa. If you claim every hour means 24 times in a day ( which seems impossible) , you earn as little as a few paisas not even a rupee a day for all your mind, your phone and internet.
Then the minimum payout is in dollars. Making a dollar can takes 2-3 months and even you are not sure if you get money or not. This is what happened with me.
So it’s total wastage of time, internet data, mobile battery and mind as well.
