ive lost $30 and somehow i got it back but not from gambling
i did some tasks for btc like captchas etc
Its probably next to impossible to make $30 with captcha solving. Unless you maybe were solving captcha's 8 hours a day everyday for a month. They pay like $0.50/hr.
yup, there must be other stuff he has to be doing to gain $30. captcha and freebies and faucet is gaining too little. Maybe signature is a more feasible choices.
I agree, signature is the best way to earn and it is not boring by doing this, you earn money while commenting of the topic is the best idea cause you also educated yourself on the bitcoin and altcoins community.
