A 500% -1000% increase (based on current USD price of ~$0.50) by end of 2018 is realistic, that is if POWR manages to gain publicity as well as stick with their roadmap to deliver their products and application.

The problem at the moment is that most of us trade POWR in return for Bitcoin, and bitcoin just went up by 200% in the past 30 days. For as long as you trade POWR for BTC and BTC is going up by 25% per week, trader like us will have a hard time to justify investment into POWR.

• I invested 0.2 BTC into POWR ($1815 worth of the bitcoin at the time) in return for 2200 POWR. Now that POWR is worth 0.07 BTC ($1290). A loss of 30%.
• If I would have invested using US dollars for the same amount of $1815 instead, I would now have $1672, a loss of 8%.
• If I would not have invested into POWR, I would now have $3886.93. So I basically lost almost 70%, just because Bitcoin went up so crazy.

That's the downside when trading paired with bitcoin. Even though bitcoin is extremely volatile, going up and down 20% - 30% per day, at the end of the week, Bitcoin has been 20% - 30% higher than the previous week, and it has been doing so for the past 10 weeks.
