what kind of a move, percentage wise, is needed to trigger margin call assuming you are fully leveraged?
Depends on tolerance of the trader.
But say u have 10K, and u leverage 2.5:1, you can then trade with 25K worth of BTC. This means that a $10 in the wrong direction can end hitting you around $500, and then there also seems to be more ass-fucking on top of that with Bitfinex, such as sell - orders going well beyond the price that you had set to sell at etc....
So from the exchanges point of view, it is probably a very lucrative business to have a bot that sweeps up all those mis-placed bets during low volume stagnant periods. If you know where the weight of the bets are placed, it is easy to instigate a little trading action that will squeeze leverage users out of short and long positions. If the majority are short (cos that it what TA 101 tells them to do, then drive the market up, if they are long, then smack it down a bit).
I was personally challenged on this forum by one of the Bitfinex exchange team/owners for stating these suspicions previously. But I don't give a fuk. I think they are corrupt. We now know for sure that Karpeles was at it and it and in all likelihood, they are at it on all exchanges to some extent. No regulation, no oversight, daily temptation to make serious sums of money by rigging the game, just a little, and then perhaps a little bit more. They have access to privileged market knowledge, they know to what extent they can use their fractional reserve Bitcoin systems to push real Bitcoin's into their koffers without risking market movements leaving them 'negative Bitcoin'. Not so obvious when market is moving. When market is stagnant it is downright blatant what is going on.
This is why I generally don't trade with Stop Losses. Too many times have I come to my PC and seen my stop loss triggered right at the very tip of an erratic spike and then the market progress to put my trade well into the green, if I hadn't been cheated out of it already. This will likely explain why BTC-e and Bitfinex are generally more volatile or noisy than Bitstamp. The 'noise' is all the leveraged stop losses getting wiped out.
Just SECONDS before BTCChina announced adding litecoin, a whale put in a massive buy order for litecoin at 14.5 and sold around 19 on BTC-e.
Everyone saying that bitcoin is revolutionary because it is controlled ''by us'' is a fool. It is controlled, but not by the federal reserves, just some other dudes who entered early and now have some sort of a monopoly on bitcoin.
Probably. Anyone involved in the operating and running of an exchange, is more likely than not a crypto-currency whale.....Painting the tape? Front-running? Price fixing with fake volume? Oh no, these guys would never do that. It is only nasty bankers in the dirty fiat financial world that get up to such underhand dirty tricks. Bitcoin is the money of liberty and freedom.
