I dont think investing here is a very good idea. Not much money is raised or will be and with many other good projects like Let it ride or chesscoin I dont see why anyone would want to invest in this.
I was going to invest here because placebo seems like a good guy but like you pointed out, only 6 btc invested so far its not looking too good.
I think even placebo knows his investment in LIR is a much safer investment then dlisk right now. I could be wrong but I believe that in 3 months LIR will be outperforming dlisk by a mile.
Sorry placebo but at least you invest in LIR so you'll make some good money with that one.
