Hi,
Thanks for your response.
I did invest a small amount into Drip, simply because I believed the timing of the investment was good (in hindsight, it wasn't that great ;-)). Drip obviously is an extremely risky investment and therefore I would not recommend anyone to invest into it, unless they accept the possibility of losing all their money.
Because I wouldn't recommend anyone to invest in Drip, I also didn't include my referral link in the post. And the referral link that I used was the one of the development team, not one of any shiller.
As you state: this has been a small calculated risk for me. Nothing more, nothing less.
