Free lotteries
The easiest way to get money without investment is to participate in the free win-win lottery Social Chance. To participate, just register, select a sequence of numbers and press "play".
Verified - getting paid! I personally have withdrawn money several times, won small amounts (maximum 1 ruble), I saw winnings among my referrals 10 rubles. The site stays in the black even when it pays out, because he gets money from the sale of advertising spaces: большая посещаемость + ban on the use of AdBlock.
Revenues from this site are scanty, but without any investment you can get a small win. Pay from 50 rubles. Собственно это единственный способ точно получить выигрыш.
