Most Czechs believe that keeping the Czech crown is better for the country than adopting the euro, according to a survey by the Ipsos Tambor polling agency released on Thursday. Some 88 percent of those polled said that having the koruna is an advantage, which represents an increase of 25 percentage points since the previous poll in November 2008; only four percent believe the crown can bring the country economic problems. Some 88 percent of Czechs who took part in the poll also trust banks, an increase of 6 percentage points.
