Every 5 minutes you can get 0,00001 ltc. The payout is 0.02. Some calculations:
You'll need 2000*5 minutes to reach the limit without sleeping. That is 166 hours, about a week. After that you'll get 0.02 ltc worth ~ 1.2$. Seems not good enough. Except if you got a lot of referrals, then you won't have to do anything. monjam made a lot of giveaways so I used the given referral code, and done a round, but after calculated the stuff above deleted the app.
