Very easy. You don't need to scam others or any crazy luck. Just get yourself a full time job and another part-time job, and you can easily make 10 bitcoin in 2 months.
wow 10 btc on 2 month
how can do it??

Have you really read my post? As I said, get yourself a full time job and another part time job.
10 btc sounds a lot, but it is just $3200 at current market price. You can earn that easily with 2 low-paying jobs in most places.
Depends where you live.
3k dollar is more than enough for a whole family in certain parts of the world.
