What happened on the previous years is that, whenever the market value of Bitcoin is pumping, same thing happens to the market price of altcoins. I am not saying that altcoins are dependent to the market value of Bitcoin, what i am trying to say is that, both are dependent to the market movement in general, there is a parallelism most of the time. My expectations regarding this is that, things could either go the other ways or the same as before. Bottomline is that, it is hard to predict what could happen after halving due to the situation right now wherein some people are having low hopes of recovery even if halving take place.
