And I think the faucet always pay you around 2 RP or may be on weekends it can bit 5 RP
Wrong. On a 5x reward point weekend 2*5=10
There are the reward poins bonuses also.
I sometimes pay my 1200 rp on a day where I know I'm not doing very much and claim about 16 times so I get my +400 points for not so much work.
and they do not limit on how much you can claim each day, as long as you do not using any third party bot then it is fine. So it is still possible to have all those RP claimed. Just need more time to do it
You can't use a bot to claim the faucet but there is no restriction on using dice bots eg.
https://bot.seuntjie.com/I get too carried away with bots and end up losing quite a bit. My strategy works so I stick with it until it doesn't and it's too late

Edit: How about this. The guy that has wagered 94.00074000
BTC in the last day to challenge for the wagering competition has just won third place in the lottery with the 18,560,901 free tickets they got.

He's not got much back though in comparison to the 94
BTC.
Just ~0.36
BTCAlthough he might have kept some of that 94
BTC (hopefully).
I think we should have a biggest loser competition at some point and see who wins/loses that one?
Surely the 94 bitcoins are not the amount that he lost, but rather the amount that was wagered.
He might have won a large percentage of that and used his winnings to finance his bets. I think the fact that he changed tactics, by dumping coins into Lottery tickets, is an indication that he figured out that he is losing more than what he is gaining.
It would be great if this guy could do a little AMA here, so that we can talk about his strategy and if he/she can tell us if it was worth it.
