In a country like Colombia, what would be the advantage (or disadvantage) of changing their currency to dollar

Question

Do common people obtain any advantage? In Ecuador, they have already done it and people complain that everything is too expensive. In Italy they have the same complaint about the Euro.

Answer 1

The advantage is more on the international scale.
is equal to
0.743 European Union- Euro
1 euro is equal to $1.34 dollars

0.53 Britain- pound
one British pound is internally equal to $1.98 dollars

10.77 Mexico- peso
1 peso is equal to about $0.09 or 9 cents
2320.00 Colombia- Pecos

these are what each counties money is worth when they wish to purchase items out of the country. This is how you incur an international dept

If some one in the u.s buy something from Europe at say Macy's for a $1000.00
the amount of money that goes back to that country is $1340.00 dollars. This is how counties pay for good made out side of the country.
