The BᵢₜCₒᵢₙ Cₒₗₗₐₚₛₑ of March 13, 2020 reminded us of the one caused by 𝕄𝕥.𝔾𝕠𝕩 in 2013.
Bitcoin dropped to USD 3700 in a matter of hours.
What will we see?
✅Market movements
✅BitMEX case
✅PlusToken case

𝟙) Seeing some movements you can see that in those hours there were several million dollar transactions (1000, 2000, 3000 BTC moved to OKEx)
47,000 Ether (single transaction) and 89 million XRP ($ 7 million) have also been moved to Bithumb.
BitMEX has recorded ALWAYS SINGLE record transactions: 3000 BTC (16 million dollars) and almost 89000 Ether (10 million dollars).

𝟚) To be criticized was the controversial BitMEX exchange that in the hours of maximum decline went temporarily offline with their liquidation engine which went deadlock.
The other reason regards the liquidations which at a certain point would have exceeded the liquidity available on the order book causing the collapse.
BITMex then went into maintenance, perhaps voluntarily (otherwise Bitcoin could have gone down to 0 dollars).
On Twitter, BitMEX revealed that the services had been disabled for about 25 minutes due to a technical problem, resolved at 3:00 UTC.
Some members of the community advanced the hypothesis that the exchange initially contributed personally to the collapse of BTC
The next day the platform went offline again following 2 DDoS attacks.

𝟛) In June 2019, some of the operators of the Ponzi PlusToken scheme ($ 2.9 billion) were arrested.
A researcher who tracks PlusToken's activities had reported that the criminals recently liquidated 13000 BTC: the price of the cryptocurrency quickly plummeted in the following days.
Up to March 9, approximately 13,000 BTC had been sold, equivalent to $ 210 million.
To make tracing stolen funds more difficult, criminals use mixing services. Two wallets have been identified that have suddenly liquidated large quantities of BTC.
The big problem is that there would be undistributed 61229 BTC (USD 369 million) that could cause the market to collapse.
