Cryptocurrency well known as a high risk investment it's written everywhere. So if people did not fully aware and learn more about this then it's their own fault.
Sure we can say that it's their own fault. But the thing is, they saw an opportunity to make money--or should I say easy money. But then again, last December 2017, the price of Bitcoin is very misleading, the fact that many people don't really know that much about Bitcoin, they thought it's the "real" price of Bitcoin. Little did they know it was a fluke--a bubble as we call it here. Due to unfamiliarity, many people jumped on the train and didn't actually know where it's heading. So when the price goes back to its "respectful" price, people panicked and get devastated in the end. That resulted in discouragement on using Bitcoin, and we thought that it was the start of Bitcoin to have its well-deserved recognition.
So my question is, who is to blame? The people who blindly invested in Bitcoin or the people (aka Whales) who pushed the Bitcoin's price to be a bubble?
That's not true. Some things are inevitable, even if you train so hard, learn so much, there are always things/events that you have no control over of.
