There's a big, smart short with pockets deeper than a whale puss that's gonna wreck any futile attempts at recovery.
It's just the way it is. Don't shoot the messenger.
The problem for the big pocketed folks is that unlike the gold futures market or the stock market you can't naked short BTC. You actually have to have some to sell or borrow.
This makes the market much harder to control hence the weekend attempts when people can't get fiat onto an exchange.
What does the weekend even do to keep people from "getting fiat onto an exchange"? I've never understood this. Any wire will have to be sent days in advance anyway.
You seem to be conflating a couple of concepts. ACH deposits take several days; however, there are a large number of wire services that can go through in less than an hour. I have done several wire transfers that cost me only $15 and the amount of the wire does not matter, and there are likely similar services for other people - possibly they charge more - but their speed can be quick for those paid-for services and well worth the amount of money, if the sender believes that s/he can profit grater than the amount of the fee.
I know this may be crazy to conceive but have you possibly thought that there are people who both own a lot of BTC and a lot of fiat? I know, crazy right? Who'd think that the two would be in any way correlated.
You are again engaging in distraction here. You certainly can have a lot of money and if your goal is to merely attempt to debilitate bitcoin, then you can spend a lot of money in such an attempt to buy and sell at a loss. However if you don't want to lose money, then your options are going to be more difficult because sooner or later you are going to run out of coins.. sure, you may be one of the richest folks in the world, but even rich folks do not like to throw away money if it does not serve any purpose for them.
So, sometimes a lot of small buyers can overwhelm a group of whales because they run out of coins (that is if they keep selling them, sooner or later they will run out).
