1. Most journalists can't read and write stupid articles just to get paid. The Wall Street Journal article literally said that SpaceX has not reported to own bitcoin anymore, which means they sold before the WSJ came to know about it, right? This means that they sold last week, or the week before, or at some other, earlier date.
There's not a single proof that could confirm that the recent slide was caused by Musk!
2. The market lacks liquidity and is prone to manipulation. You could see it as some exchanges were crashing to 25k while others reported 26k. This means the price is not the value and there can be a temporary trading price and a real price derived from the weekly or monthly averages. If you see the price much lower than a 30 day MA, it shows the asset is undervalued at the moment and you shouldn't sell.
3. Someone is manipulating the markets by spreading fake news, just like they were doing in 2014 when China was banning bitcoin every single month... People never learn.
4. Bitcoin Magazine sucks.
If you have some money it's a good idea to get more BTC. You'll thank me in a few months
