Why use copper instead of copper carbonate to prepare copper sulphate using sulfuric acid

I want to prepare copper sulphate using sulfuric acid. I have a sample of copper metal and a sample of copper carbonate. If I'm to use one of the materials which should it be and why

Copper metal will not react with sulfuric acid . ( Copper metal is too unreactive / it is " below hydrogen in the reactivity series " ). So use copper carbonate, it reacts easily to give copper sulfate ( and carbon dioxide and water ) .
