mastercoin, how will future people get mastercoin?

[stslimited]

Hello, lets say I want to speculate on gold in the blockchain

are you telling me first I would need to buy bitcoin, then buy mastercoin with some of my bitcoin (lowering my bitcoin balance), AND THEN buy an amount of gold with mastercoin, based on my remaining bitcoin

help me understand this, but for the record the way I interpret this seems prohibitive for adoption

You will have to have either user currencies or Bitcoin.

You can trade both for MSC
