I really don't understand who invests in that shit anyway. How about give it a rest and see how the market evolves without it

How will you not know who invests into BCH? It is guaranteed that the same people bag holding BCH, whales manipulating it and their victims are the ones investing and keeping that shitcoin alive. Do not worry to much about it, it is just another alt and it is not affecting the crypto market but rather too much drama(FUDs) are the one responsible for keeping bitcoin and crypto market behind. IMO, we are already seeing their end because institutional money is starting to flow into crypto space.
