I am also doing same most of time using these RP for bonuses from time to time because no other use of these RP and 100K need nearly 9 to 10 years for redeem which is really hilarious for any single user without any referral and gambling habit on this faucet.
I'm sure this is intended to be like that, otherwise anyone would just bleed the faucet dry after few months.
This gives you incentive to play hi-lo and to bring in new people into the system.
Also, if you claim the faucet regularily, like 15+ times a day every day, you can buy RP bonus which increases your RP gain a lot.
