@rds I do not understand why I should have remorse, I have not recommended anyone to invest.
These systems have unfortunately always existed. I do not know the experiences of the others but an interest of 30% per month that I know you do not get it anywhere and if give it, you suspect.
I always recommend the same to everyone who asks me, if you have 10 BTC that you can afford to lose, how much you invest 10%, and the pain will be less.
In this case, I've been very lucky to gamble that 5% since at first I thought I lost because when I sent the bcc to hitbtc it had a value of 23, I think, but the next day it went up to 69 and I sold in 60 If I had not expected, I would have lost.
With these systems I have tripled the inverted, but I have also lost, but what I never do is recommend it to anyone and if I do it because they ask me, I am very clear about what this is
