Its some great wins you have got there , really appreciate it . But I want to know whether you had the knowledge about the sports and hence you placed bet on them , or followed some tipster? Or is it just pure luck ? because this is some great amount, you can start your own professional tipster service . Since you have mentioned that you will be happy if it becomes your job.
woa, 15btc is a lot to me. it will takes ages for me to get to that amount. if you can earn 15btc in a month, that can be a full time job for you. hope you continue to win more and more.
Some times , its not that tuff , you just need pure luck . See this
