Maybe read the white paper for starters,
https://powtoken.com/POW_Whitepaper_19_09_2017.pdf Educate yourself a little on POWtoken & Pow ERC20 and what they are trying to achieve with the
231 BILLION POW tokens that are being issued.
Then have a look at the contract
https://etherscan.io/token/0xeb2da9fac54284cea731d1f10bb34eecb3c00c14, where you can see trades and holding accounts for POW, quite transparent, as with anything new on any market the issuer/owner/dev has an idea of the value, e.g. an IPO for stock or as we see now an ICO, you buy it for the issue price, then when it trades the market will tell you if it is actually worth that,right? Here the dev's are trying to form a market, for something that cost most nothing. For illiquid stocks etc, we have market makers who in many ways control the buy and sell price. But with etherdelta and some of the erc20 already in the market the devs can't do that to the same extent, I mean really? a scam that would make them what? sell 2219779.000 POW = ETH19.978 approximately $6,053,
Seriously have a look at the white paper, look into the back ground of who the dev's are, but also the fact that it cost nothing to get involved just enjoy the ride, quite easy for folks to throw the word scammer around these days without looking at the full facts!
