Central and Eastern European Countries have faced many challenges on their way to well functional market economies and to their European integration path. After their EU accession, next challenge was to fulfill Maastricht criteria for adopting euro and entering the euro-zone. There is no easy way in achieving both nominal and real convergence with the most developed European countries. The nominal and real convergence criteria are rather contradictory. That's why the Central and Eastern European Countries must find the best solution for them. Are they prepared for European Monetary Union? How soon will they fulfill the convergence criteria and will adopt euro? What are their perspectives in the actual crisis context? These are the main questions we tried to answer in this work.
