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.
From my personal experience, I would say that to claim the FreeBitco faucet for 14 to 17 times on daily basis is totally unrealistic, except the person have more than 24 hours a day or he or she does not sleep.
Each claim takes one hour, and to claim 14 times means 14 hours, while 17 times means 17 hours, minus 14 hours from 24 hours, we have 8 hours left - (this is still a bit realistic though).
Now minus 17 hours from 24 hours, and we have 6 hours left, and to me, it's unrealistic to claim the faucet for a whole 17 hours in a day without missing a single turn, this is if we even disregard the fact that sometimes, one may not even be able to claim due to ip address issue.
I myself used to be very committed in claiming the faucet, but in all my seriousness, I think the highest I used to claim it in a day was 6 to 7 to 8 times, but this days, I usually only use the faucet ones every 24 hours, lol.
