freebitcoin is a scam, load the site and open the statistics, then turn off the internet and you will see that the statistics are in progress, registration continues, how is this possible???
That's just an animation. The statistics displayed on freebitco isn't updated that fast. It's updated once per hour and if you refresh the page, you will see that the numbers change to the same amounts as they were after the latest update.
You can read TheQuin's post below for more information.
The stats page is cached on Cloudflare and it updates hourly. The counter just runs at the current rate of increase so when you refresh the page you go back to when the page was last updated.
