Luxembourg-based bitcoin exchange Bitstamp has initiated internal investigation amid suspicious large sell order of bitcoin (BTC) at $6,178, which lead to a short-term drop of bitcoin's price.
1/2: A large sell order was executed on our BTC/USD pair today, strongly impacting the order book. Our system behaved as designed, processing and fulfilling the client’s order as it was received.— Bitstamp (@Bitstamp) May 17, 2019
Even though the price rebounded, the exchange claims it closely examines "every event that causes large-scale movement" in its order book and has started an immediate case investigation.
Some people suggested that the suspicious large sell was nothing else but laundering of stolen bitcoins from cryptocurrency exchange Binance, that lost a week ago 7,000 bitcoins as a result of a hacker attack.
So 7000btc was stolen from Binance weeks ago, pretty sure we just found it— Freak Society (@freaksociety) May 17, 2019
