According Samson Mow; Some people hate Bitcoin with an intensity that doesn’t make sense. You need to ask yourself why, and what exactly Bitcoin threatens for them to behave in this manner.
I think some people needs to understand that bitcoin is no man's business concerns. After all nobody is using another man's money to invest. Bitcoin could be greater with time, let's leave the hates about bitcoin.
I came across something similar.Most likely, hatred comes more from a misunderstanding of the principle of operation and its main function. when I asked why exactly I didn’t like Bitcoin,they answered that it was a currency for the dark Internet and that various kinds of scammers actively use it, and all this was created only for them. After that, I did not even try to convince the opposite person.
