Who did an exit strategy before the worst dip?
Those that saw the signs were the luckiest, First it was Elon tweeting negatively towards the market then the Chinese government saw it as an opportunity to carry on with their usual seasonal fud of them banning bitcoin related transaction so as to create fear in the market, cause a dump in the process and proceed to buy as much bag as their pocket can achieve.
The they proceed to clear the air on what their latest ban is all about and when you look closer it doesn't have any or that much effect on bitcoin operation in that region. But since the news came in a time of fear it'll definitely be viewed negatively and causes panic in the community.
This steps were chosen with intentions to manipulate the market, this isn't the first and obviously won't be the last therefore we should be familiar with this fud by now and use it to our advantage instead iofbeen at lose each time it does occur.
