Thank you!
It's true that no currency, despite all the security measures taken are safe from counterfeits and frauds. I have always felt that certain people are always reluctant to accept the advantages of a new technology, especially something that can become very important sooner or later. Such people tend to focus on the negatives, as if the existing methods have zero negatives. May be bitcoin and other cryptocurrencies like ethereum are going through that kind of a stage and which is why many countries are still reluctant to accept its validity.
I am sure it's not going to be easy for people to protect themselves against ransomware. I agree with you as threats like ransomware are caused by people and their lack of proper knowledge and awareness.
With my little knowledge, I think cryptocurrencies should be more popular than they are today. I hope it will be, sooner or later.
