SFbay,
I'm not on one side of the fence or the other; i'm on the fence and riding the uptrend as it continues. It's like with anything else, what you hold is only as good as what someone will pay for it. I don't foresee it going to $20 either; but to make a buck you have to sell.
You got all these folks jumping on and saying I'm going to wait until $50. I'm sure there are folks that have been doing this well longer than I have and too me these prices are higher than I would have even liked to sell at / even dreamed. I started when silver was 11 an oz in the fall of 2008, and now it's 33. I remember picking 20 at the time as my sell point. I've sold at 23 an oz and 27 an oz and don't regret it at all.
When I was a kid I used to collect baseball cards and used to look up the prices in beckett's. I was always like this card is this much, this card is that much, and never sold any. Now they are worthless other than the few rookie cards I have scattered across a decade.
I guess I urge all on here to sell at some point, now, or at $50, or at $75. Because if ya don't I'll be the first to say... TOLD YA SO, when it comes back down to earth. All good things come to end sometime...right?
