We have seen some people or groups, who claim they are hardforking ETH,.
The plan of the first, NOVA, whose intention was to scam others of their hard earned money, was foiled early enough, because it was using a fake.
ETCV on the other hand was not quickly detected, but its team was anonymous, which i feel is enough to suspect them of scam.
Right now, its telegram account has changed when i checked.
It's website is suspended and so on.
They are now asking people to buy their coin, which does not exist.
Therefore, the only genuine hardfork, is the constantinople.
It's sad that many hard fork events created under this event. NOVA and ETCV are officially scam projects after they require participants to use private keys to receive free tokens from them. So rely on official information and be supported by large exchanges to avoid risks.
