when i can reach $10?

It is a very individual thing. Some have more time and a better knowledge of English and will obviously reach payout before you. Your English is certainly much better than some users here so please do not let that stop you joining in. Try responding to other discussions until you have learnt your way around and feel more at home. Try to write quality responses of about 4 or 5 lines and gradually you will be earning too. Welcome and happy Lotting!
