I read the article and seems not so detailed.
But here's what I can say; Bitcoin is not safe haven for my money.
Because I do believe the risk when I started to buy Bitcoins and store it for long term.
Although I already know the risks, I am still supporting Bitcoin, why? Because I am not just totally into the money will return of Bitcoin, but it's also for innovation or technology behind Bitcoin.
The article is linked to a video, you should watch the video first. Yeah but true that any cryptocurrency is never safe to store and for life savings. only people who have strong balls who dare to invest all of their money to cryptocurrency. But in the end if it's running well, they will have a lot of profits compared to any safer investment
