I would not power down now, i would gladly wait for wath the future could bring.Alot of good points @dantheman.
I also think many others here do the same. It is cheap power now, so for mee it is a buy stage in a bigg growth. I hope others do the same to get a bigger stack.
Steem dont have so much supply that i am scared for a crash. As long there is trust, there is value as you describe.
Keep up the good work :)
