I have used this site of 2 captcha and according to my personal experiences I want to share this review to all of you.
Actually if you work on this site daily 7 to 8 hours after words you can withdraw only 500 to 600 it is my personal experience and it is not a legal site this site misses to give money several times but sometimes it pays. Why this site gives us captcha to solve? We can see everywhere in applying ticket of airways or railways it has to check you are a robot or human so in this case whenever a robot make a ticket they send their captcha site of to captcha and to captcha force us to solve this captcha and when we press send option after entering the captcha it automatically sends to this robot.
So according to me it is not a good site that pay every little amount and force us to do illegal work. So I hardly request you to dont sign on 2captcha.
