I think hardfork is not a scam or legit problem, but it's a matter of whether or not an exchange support the hardfork. Not all exchange support hardfork, some exchange considering in terms of security and hardfork wallet resistance to minimize risk and loss.

I mean it's nothing new in the cryptocurrency market. Forks, like new altcoins, can happen at every time due to the doing of some developers, maybe to serve their very own purposes or with the consideration of the many cryptocurrency users around the market, who knows. I think it holds the same water with B2X, it's something new that may not be impacting in the market, but you can't blame those who introduced it because maybe, they just want to make something for profit. Every coin in the market, including bitcoin, started from humble beginnings, so I don't think it's a scam, it's just a small-time player that has to apparent and major impact.
