Silver and Bitcoins go hand in hand. I bet somebody could make a lot of money contracting a mint to make THE (it would be THE because it would have no predecessors) 1oz Silver Bitcoin round. I'm not talking about Casascius's 1oz, 10 BTC round. I'm talking like...the copper Bitcoin rounds that somebody had made. If I had the money to invest in the project I'd do it in a second. Its a significant venture-you have to come up with a design, have the die(s) made, and have the mint make at least the minimum quantity...something like 500 rounds on average I think.
But, with spot being so low, nows the time to do it. I can imagine most users on here would want one, so you could command a pretty good premium for them, make a lot of money.
Like these?
