To be honest, my expectations are not that high regarding the Bitcoin halving. Maybe that is because of the situation we are currently seeing in the market and also to the fact that there's no consistency when it comes to the market itself. Not because the market prices increase after the previous halving, same thing would automatically happen on the anticipated one. There are other factors to consider, the economy outside I think is one thing.
Halving is simply cutting the supply of Bitcoin into half, correct me if I am wrong. It won't make much of changes unless the supply would be limited which would cause an increase to the demand as well as to its market value, followed by the increase of other crypto's price (more likely to happen).
