Faucet ? Cloud Mining ? Mining ? HYIP ? Any more ?
trading is best way for me, because i can earn a lot money with it.
i earn arround 0.3 perweek and for me it's high salary,
if someone could earn 0.3 bitcoin per week then it is really a very hot vague for him. but making that possible need lots of work.
trading won't give anyone 0.3 bitcoin from first week. you need manage your work well, and adjust everything first. and make a reputation in trading world also. then you can earn that much.
