Been watching the trading on Bittrex - is there any reason why the whales keep dumping through buy walls? Saw 8 BTC worth of the stuff dumped instead of allowing it to retest the 0.005 high? Seems like there's heavy unloading going on for one reason or another. If you hold 1000+ of these things why in God's name would you dump it?
to rebuy it later, like I did twice already this month

It's a dangerous game to play
Threads are full of disappointed traders, be careful

from my experience best is to hold and wait.

Are there any plans to eventually move to proof of stake algorithms?
Not for now but in the future everything is possible.
