Concerning the price and concentration: there are a few owners who have millions and the rest who can mine hundreds PRT per day.
Until the ownership spreads, I would not count on massive increase in price. Personally I would not invest much money in a coin with low trading volume and a risk of early adopters dumping all they have.
I am going to start selling at 500 and keep only 50% of what I have. For the good of the coin, so my remaining 50% is worth more:)
Yes. The current technical structure of the CoinedUP exchange is not helping with liquidity. I personally have exchanged PM's with potential traders who
are hesitant to signup/use CoinedUP's service due to the latency issues experinced with them.
This I am sure will be resolved with relentless pressure towards more established and technically stable exchanges.
