you're getting murdered
I'm going to give you a loving but stern bullshit call here. The first 2 articles you listed cite a well known spoofing case on the part of JP Morgan traders. The last one is a blog on a gold bug site, so to be taken with a massive grain of salt, and even it seems to just be talking about the spoofing issue. Spoofing has nothing to do with "writing futures contracts", it involves spoofing, and I know that you know what that entails. As far as "just writing futures contracts", anyone can "just write a futures contract", that's how all futures have always worked!Silver (and to a great extent, gold) is heavily controlled by JP Morgan.
Any bet on silver really a bet on the agenda and interest of They, and how They will direct JPM to manipulate its price.
It's very simple. JPM just writes (or doesn't write) silver futures contracts, messing with supply and demand, ultimately moving the price.
