In every industry or market, there will always be people whom many loves and many hates. And in Bitcoin and cryptocurrency, there is no exemption here. While hating is not a good business, expressing some dislike can be a healthy one.
As far as being hated, I can think of at least two personalities, and we know why many don't like them: Roger Ver the man behind BitcoinCash and of course Craig Wright who earned the moniker as "faketoshi" as he is continually claiming to be the real guy and behind the Bitcoin SV (the original Bitcoin, according to its site).
Can you add more, please.
Gerald Cotten, the director and owner of the Quadriga CX exchange, took millions of dollars of other people's money with him to the grave. He turned out to be a fraudster and a deceiver whom deceived users hate even now a year after his death
