Bitcoins and cryptocurrency cannot and should not be considered dangerous. Anything in life can be dangerous depending upon what you do and how you do. And anything can be considered safe. The problem with bitcoin being shunned by some people and even few countries is that they are not able to hold total control of the bitcoin network or that they have not been able to clearly understand the system or it could be both of the aforementioned reasons.
Why Bitcoins have come into existence? Well it was the result or consequence of a genius mind. Having come into existence, we realized that Bitcoins can ease the transaction throughout the world as an alternative form of currency. Total Privacy, Ease of transaction, Security, Digital economics, Transparency, Accountability, Investment, Universality are all some of the advantages of Bitcoins and cryptocurrency.
It is true that some unpleasant works keep getting reported associated with Bitcoins, but tell me which currency has not been associated with crime etc?
Trying to project bitcoin as dangerous is simply finding reason to avoid evolving. The major drawback from a broad perspective with bitcoins is that there is a need for some basic establishment in place before it could be utilized.
There is a fundamental need for Internet connection. Further, people need to operate on computers. Further, they need to understand and comprehend a little more of the subject of cryptocurrency for which a basic understanding of the economy is needed. Every individual should be able to afford a computer, electricity, internet connection, time and other basic requirements to be a part of the cryptocurrency ecosystem.
Many of us do not realize that major part of the world is fighting it out for survival and sustenance. Hence, becoming part of the cryptocurrency ecosystem is considered a sophistry. But now that there is a dramatic shift in education system and especially computer education, I think bringing Bitcoins into high school syllabus will help our community the best. We need to work our best to overcome these drawbacks and shortcomings. And yes, we are all working.
If we talk about being dangerous then, there are lots of reasons and each of us have different versions about it, and since so many people disliked bitcoin, they said its dangerous so stay out of it. Well in my own point of view there is nothing to be scared of, and besides it just depends on the certain person how is he/she gonna use his/her bitcoin. There is nothing wrong in using bitcoin, and i agree with your point when it comes to the price, that's also one of the reasons why it is risky.
