I recently discovered an easy way to get between 0.03 and 0.06 BTC every day without any risks.
So basically you have a method which is at least 4x forkable (you + 3 buyers) which would earn a cumulative 0.18-0.24
BTC each day.
Which is 5,4-7,5 a month... enough to make a decent living.
Do not sell it, spoil it.
