Ofcourse everyone knew and was aware that Constantinople is the only hardfork which involves corrections and solves scalability problems
But few people tried to gamble on those other tokens in the plan to hit and run
But they got phished
So unfortunately
No, there are about three Ethereum hard forks, but Constantinople is the major fork. I have been following up with it and I learnt that there are three which are Classic Vision hard fork, Ethereum Nowa hard fork and Constantinople hard fork which is the major thing. So you can see that there is not just only one, but three hard forks. The only thing you should focus on is the third which is Constantinople, forget about the other two.
