Numpang tanya bagi yang tahu, mana yang lebih besar marketnya crude oil atau nickel dan tins? Mana yang lebih vital kebutuhannya minyak mentah dengan kedua logam berat tersebut? Kalau dalam waktu singkat minyak mentah bisa turun dari $ 80an sempat kembali ke $ 50an, apakah hal tersebut tidak bisa terjadi pada harga tins dan nickel di LME?
