That's not easy at all, that the person keeps on doing the free roll every hour for 18-24 hrs the day (Excluding) the sleeping time. There are other activities in life too and sometimes you may forget to do the freeroll for the hour or you might be busy in some other activities and not able online for this activity. Let's keep this to a realistic target.
I used to claim the faucet 15-17 times regularly when the reward points bonus system was available on Freebitco. We were able to buy 100 RP with per hourly faucet claim for 24 hours by spending 1200 RP from that option. A lot of users were using this method and claiming the faucets 14-17 times regularly. However, it is indeed difficult to claim the faucet 18-24 times everyday without using the bot.
I used to do the same from time to time. Activate the bonus and try to be as active as possible, I think I always got around 14-15 claims a day, more is quite difficult except if you want to sacrifice sleep to keep claiming lol.
