Of course it's possible to be an ungrateful investor. I'm not saying your are one Tonyk. Satisfaction is in the eye of the beholder and rather depends on your reasons for investing and a million other things.
Perhaps there will come a time when every holder of Bitshares will be very happy, I hope so. Will that invalidate all the criticism and accusations for anyone who has felt aggrieved along the way? Of course not. All the feedback has helped to articulate this communities expectations and guide the analysis of what has been accomplished so far. It is all a rich tapestry of our interactions as we learn and implement our way to success.
I feel bad for anyone who has put money into Bitshares, lost hope, sold and lost out. It would be great if they all come back and join in the success we all hope is around the corner.
We've probably all been through periods of time where we could classify ourselves as ungrateful investors...
