Mat5X - Thank you for your comprehensive answer! :-)
PS. I think that the most important problem to resolve now is to find an idea how to create a market where new altcoin can be exchanged for services and other benefits. It is possible - on forum there are a lot of announcements like 'looking for programmer' or 'need help for create an new service' etc., but the market needs a little bit less anonymity and more trust. But how to fulfil these expectations in cryptocoins world?
Why not FRC?
Production of coins should take place on the verge of profitability, where the most important factor should be the price of energy. In the case of FRC appeared ASICs, the price is more dependent on the scale of investment than used energy. There is a risk that someone who has extensive resources will invest in mining farm and issue empty coins.
Buying currency at the exchange should be as profitable as its production.
