Plus yours is the same argument that I've been hearing for years as a justification for why PM prices should be skyrocketing (!!!). The fact, I think, is that 1) hucksters will lie, and 2) the market is glutted. And gold and silver prices, well, they're falling.
There will always be terrible versions of PMs available, and it just so happens that thanks to cheaper labor we are able to have an abundance of pieces of shit floating throughout the market.
However as bitcoins supply keeps decreasing and the demand and difficulty increasing, the price has nowhere else to go but up.
