Of course there needs to be a correlation.
Are you absolutely brain dead?
Bitcoin amounts are the only thing that is relevant.
The depth of the cluelessness here is astounding.
Ask yourself, "Why do you think the correlation is unnecessary?"
Imagine for a moment that you are trying to move 100lbs of gold across a river. Youd need a ferry. As long as its large enough to make it to the other side of the river, itll carry your 100lbs of gold to the other side. Or 10lbs of gold. Or 1oz. Or a speck. To simply move it, the size of the ferry really doesnt matter, nor does it matter how much that ferry is worth.
Bitcoin is the ferry. Mastercoin is the gold.
