I discovered GramFree two weeks ago and I like it.
At first, you get 10 Gram, a cryptocurrency that is 20 $ worth, as a sign up bonus.
Then, you can watch videos, 10 per day for a total of 1 Gram.
Every hour there is a free lottery, you play for free and you can win from 0.1 to 1000 Gram. There is also a lottery, but you have to pay the ticket, 1.5 Gram.
If you find referrals, for every referral who signs up you get 5 Gram.
All these things, videos, lotteries, referrals, and not only, give you some points. If you reach 100 points, you pass level and you get 5 Gram.
Withdrawals are with PayPal, Visa, MasterCard, Payeer, Payoneer, Bitcoin...
