1 billion dollar of BTC has been moved from a old "sleeping" account to many exchanges.
We recognize the drop of 200 points every 2 days, from MT Gox last year, if this repeats every time BTC returns to the old value $7350, we know what will happen. Yep deep down.
The user account original wallet contained 111,114.62 Bitcoins and Bitcoin Cash. This could be worth at least $844 million now. The wallet owner divided his share of coins into chunks 5,000. Now there are wallets of 500 coins and 100 coins. The coins stored in the 111,114 wallet have been moved to Binance and Bitfinex.
So, there will be a continues drop of the Bitcoin after it goes up again over a long time
