Took what I "could lose" and invested in nxt. I voted with my money because I really believe nxt has a chance to be something great. A new language, a great group of people trying to develop it. As time goes by, I have half what I put in. It hurts. But I wasn't ever intending to day trade nxt. I am in it for the long haul and continue to say good things about it! I think I am not the only one like me and hope nxt will bring about great changes.
I think your strategy as an investor is the right one - don't invest more than you are prepared to lose and don't expect to "get rich quick" from that investment.
Hopefully your investment will have turned out to be a good one down the track!
