I see that 777bitco.in is using new captchas You have to spend 30 seconds waiting for ads to run before the captchas appear, and sometimes the timer stalls and you have to start again. In 30 seconds, I can do 3 captchas on another site, so its goodbye to 777 for me.
Although it takes times, I always got 99xx over there, with 2xxx every 15 mins.
IF I really say goodbye to 777, the main reason must be their payout times (within 7 days), so 30 seconds is nth to me
