If you can click twenty times a day, every day, at the end of two months you will have 0.000024
The base reward of free roll is not 2 sat for all users. Depending on your wagering amount and the number of lottery tickets you have purchased so far, the base reward can be up to 40 sat.
I think you haven't noticed the message above the prize table.
"

My base reward on every faucet I spin is 1 Satoshi, and I absolutely understand that this is because it's been a very long time since I last made any deposit, played the multiply btc or even bought a lottery ticket on the site, at some point early this year, my based reward turned to 2 Satoshi but after about 2 weeks, it turned back to 1 Satoshi again, but then, this is of no concern to me since I really don't regard freebitco anymore.
And let me also point out that it's practically impossible for a person to click the roll button for 20 times in a day when we have just 24 hours a day, I have tried something like this in the past years and didn't succeed, I slept off when I didn't even plan to sleep and lost over 9 hours 😁
