They prolly started with much less, but have easily doubled up or more during every raid making them ~16X more powerful than when they started- 32X if you count this last one. These are technically skilled traders to begin with who would be profitable traders even if they weren't market movers and market makers. When you have skill to begin with, it takes much less ammo to push the market in the direction it wants to go anyway. Even I could walk it up and walk it back on a slow day with very low volume and--as has been pointed out several times--am just a hick fireman.
Surely they don't risk all of their capital every time. One miscalculation or piece of bad luck and you get wiped out.
They don't have to risk all of it because they are so powerful, they only risk what they need to risk. They were going to push the market down until there was a long squeeze. I have no idea how much of their capital it took but surely not all of it. The problem is there has been no real bounce yet like the other four raids. This is new. They may have been too successful in accumulating coins and now they have (like me ironically) too many coins that aren't worth anything. Yes, we can leverage them up to push the market higher, but not sustainably without a fresh infusion of fiat.
This may be an unrecoverable stall without Big Money coming to the rescue and who knows how long we're going to bleed before the vultures come in and pick over our carcasses. I am not selling, but I have to prepare for an indefinite period without additional income.
