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?
