As I see, some systems gives even more than 30% a month.
Nonetheless, I dont know, how this systems were performing a week ago. Maybe all profits are from recent bull run.
Also, I can mantion, that not all published systmes brings profit, some have zero profits for two month.
Estimating approximetally, if I will invest in all listed systems equally, I will earn something about 10%-30% a month.
Off course if cryptoworld will not collapse
