are you making this up, it was never mentioned that it will ever be cancelled, also it need an hard fork, and it go against the fundamentals rules of bitcoin...aka it will never happen
I just asked. But never mind, there were a few threads as of recent questioning whether the coming halving should be canceled, so no smoke without fire?
No it will not cancel and it will make the price of bitcoins increase. But the supply of bitcoins will be limited into 21 million soon. Don't believe that rumors that bitcoin halving will be cancelled.
Bitcoin halving will be surely done in the month of July and its not gonna canceled, so investing in bitcoin at a moment is the best thing to do.
But No people can give guarantee bitcoin will be rise after/before blockhalving done
so better sell some of your bitcoin now and save some for future too.
