Some people want to be locked in a 2 year contract!
You can do that with the new changes too, even 5 or 10 years if you want.
Let me ask you one question
How much of your personal hard earned money did you invest in steem power? ( and if you have proof for it even better)
The reason I ask is because the perception of people who invest their money VS people who invest their time is very different.
People who invest their money want a return, people who invest their time are more likely to want power than money.
The problem is that this platform can't survive based on only people investing their time alone, to support the rewards you need investors that don't necessarily want to participate but want a ROI.
