It's really hard to earn more than 10BTC now especially the price of the bitcoin is sky high, many people are struggling like me to even earn 1 BTC and that's no surprise because many people have started earning bitcoin when it got popular or when the price went high. There are many ways to earn bitcoin faster than signature campaigns and faucets but you need skills like coding, developing, designing and etc. so that you will be able to really earn high amount of bitcoins but its really hard to get those skills if you don't have any background of those or if you did not go to school for those specific areas. For me I'm still studying to learn to code and hopefully I'll learn and be successful in the future.
