At present, I'm not interested in selling, as I'm building. After my initial investment, I had and emergency and sold well over half at relatively low price, and have since been rebuilding. I'm above where I was, but I'm not where I need to be.
Once I hit the range I'm aiming for, I'll be selling approximately 25% of my stake income for the sake of moving the chain, and profit taking of course, but I'm not in a hurry to hype HYP. It's been growing at a fantastic, and frankly, frightening way so far. Given it's open ended nature and very high rate of POS, I would have been quite happy for it to stabilize in the 1K satoshi range. 6 times that scares me, given how much more there's going to be.
That being said, this seems to be one of maybe three High POS coin communities that understands that the POS function is the same as mining, and that more staking coins equals a hedge against rising difficulty or lowering price. This is cool! I doubt that the price can sustain, but then again, I never thought it would get this high.
All of the above militates towards ALL HYP stakeholders holding far more than they sell. Make the price of entry a bit high, even with the high rate of coin generation. This will tend to preserve the value over time even as the supply expands.
Well done, so far, people! This experiment has gone rather amazingly well
