We know as hard fork is due in next week.. that meets scalability issue ..
ether is fallling these days and so are altcoins maybe because bitcoins value is still rising higher and also due to the upcoming fork that been said will happen on mid october and november but after these upgrades has done for sure etherium and all altcoins will be back to their normal price and would start to pump high again and maybe the bitcoin would drop again back to 4000$.
