So 40% of BTC is owned by 0.1% of Bitcoiners:
https://bitcointalk.org/index.php?topic=316297.0 (1000 people own 5.8 million coins)
How will the market respond if someone decided to dump 30k or so coins? We will be back to single digits for the price on a single exchange. Could be done by someone who was in a bad mental state. A depressed guy.
So how long would it take for the market to recover?
That 1000 people own 5.8 million is falsified information I think.
Are you sure it's not 1000 wallets own 5.8 million? (exchanges have several 100,000 often)
