yes the amount is huge but it will only have an impact once they sell this amount of btc to an exchanger and will surely cause the price to dump hard .
i find this amazing because btc is also being auctioned , what i thought is that physical stuffs are mainly being auctioned . they are smart because they want to earn more other than selling this directly on an exchange . also , the winner of the bidding can also loose because the value of btc can still dump
Hmm,
Good Question,
Just added up all of Bitcoin Liquidity according to CMK , Total is $122,684,676
So if all 4000 Bitcoins were dumped on all 400 exchanges at once with no regard .
4000 x $10000= $ 40,000,000
So $122,684,676 - $40,000,000 = $82,684,676
Price of BTC would plummet, how far depending on how they spread it out ,
as they could wipe out the entire liquidity of many exchanges , if they so choose too.
But doubtful they do the above. (The Price they paid for Bitcoin in the auction will be their price floor for selling.)
Odds are they hold and sell slowly near the $10K peak, so be ready for an $ ceiling to be set that won't be broken for some while.
Danger occurs if they drive the price below the operational cost of the miners and hold it there, until they bankrupt a large portion.
Miner Operation Costs should be close to $10K per bitcoin once the halving occurs.
FYI:
No single exchange had over $5 million dollars Liquidity for a single market.
